Using Platform.sh with BodilessJS

Bodiless starters ship with standard configuration files and helper scripts which make it easy for a bodiless site to be deployed to platform.sh.

If you are only looking to host the static site (production and static preview environments), then other options may be cost effective. We recommend using platform.sh when you want to host your edit environments in the cloud, so that content editors can update the site without having to run the Bodiless application locally. While you can host your production site on platform.sh as well, the most economical option for many sites will be to host the edit environments on platform.sh, while keeping the production site on a different host.

Bear in mind that you may not need to host edit environments in the cloud at all. You can derive many of the benefits of using BodilessJS by running the edit application locally.

Setting up your project

Pre-requisites

A Platform.sh account. Sign up at https://auth.api.platform.sh/register?trial_type=general.
Note: Bodiless deployment on Platform.sh requires at least 15GB of storage available, so you will have to upgrade to a paid "development" plan and upgrade your storage as described below.
A GitHub Account
Note: In the following instructions, GitHub is used as an example source code provider. If you're using a different supported provider (e.g., GitLab or Bitbucket), adapt the instructions as needed.
A Platform.sh API token
A GitHub personal access token.

Create a Platform.sh organization and add a payment method.

Go to https://console.platform.sh.
In order to add payment method create an organization first.
1. On the top right corner click on the user name.
2. On the drop-down click Create Organization
3. On the "Create Organization" page fill in the organization details.
4. Click Create button.
Once the organization is created proceed with adding billing details.
1. On the top right corner click on the user name. For now there should be your organization. Click Billing.
  - If no organization appeared in the drop-down, go to the "All Projects" page by clicking the Platform.sh icon top left corner, click on the All projects drop-down and select the organization created previously. After that follow the instructions provided in point above.
2. Fill in the "Credit Card" and "Billing Details".

Create a Project

Switch back to the "All Projects" page and select the organization.
On the top right corner click Create Project button.
On the "New Project" pop-up click on the Create from scratch option.
On the "Details" tab provide the project details.
Click on the Create Project button.
- In case of "Plan & Pricing" pop-up click Continue.

Add necessary storage.

Go to the project page and click Upgrade button near the development Plan.
On the "Upgrade plan" page scroll to "Storage" option and select 15GB from the drop-down. Click Save on the bottom right corner and Back To Project on the top left corner.

Run the provisioning Script.

Switch to the project root on the local machine, e.g. ~/bodiless-minimal
Using command line run
```
npm run setup
npm run psh:setup-starter
```
Make sure that all of the requirements listed are met.
. You will also need your GitHub username and password.
Provide required input parameters. The script will return 'Success' response to the console, if all the parameters were provided correctly and integration with Platform.sh and project variables are created.
After integration is created the deploy of the main branch will be triggered automatically.

Troubleshooting an Customizing Setup

409 Error from Platform.sh API

This usually means that a previous automated or manual provisioning was attempted, leaving some variable definitions or integrations associated with the project. To resolve, visit your project setting on platform.sh and remove all variables and and integrations, and then try again.

Verify the GitHub integration

Visit the "webhooks" section of your GitHub repository settings, eg
```
https://github.com/project/repo/settings/hooks
```
and verify that a webhook to platform.sh has been added. Note you will need admin access to the project in order to view the webhooks.
Activate a branch in your project (as described below) and validate that an environment is created and deployed to platform.sh. Note you must first push the branch to GitHub.
Issue a PR to your repository and verify that the PR branch is deployed.

Customizing Hook Implementations

Bodiless starters includes default implementations of platform.sh build and deploy hooks which should work for most Bodiless sites. However, should your site have special needs, you can customize by creating a platform.custom.sh or static.platform.custom.sh script and placing it alongside the appropriate .platform.app.yaml file (at the root of your repository for the static site, or in the /edit directory for the edit app). In this script, you can define for each platform.sh hook one of the following functions:

prepare_{hook} () - Run before the default implementation of the hook.
hook () - Replaces the default implementation of the hook.
finalize_{hook} () - Run after the default implementation of the hook.

If you wish to extend the default implementation, you can do so by calling it from your function. To do this safely (ie to avoid errors if the default implementation doesn't exist) always use the invoke helper:

prepare_deploy () {
  invoke default_prepare_deploy
  # Your custom logic here...
}

Configuring an NPM Private Registry

If you wish to install packages from a private registry, you may do so. The packages to be installed must be namespaced. Set the following 3 environment variables on p.sh. All variables should be visible at both build and run time:

env:APP_NPM_REGISTRY: the full path to your registry, eg //my-artifactory.com/api/npm/my-registry/.
env:APP_NPM_AUTH: Your NPM authentication token. This should be marked as sensitive. To obtain your token:
1. Login to your registry:
```
npm login --registry=https://url/of/your/private/registry
```
  Follow the prompts with the username/password/email of the account you wish to use for p.sh automation.
2. Examine your .npmrc file (usually located in your home directory). You should see something like
```
//url/of/your/privateregistry/:_authToken={token}
```
3. Copy the token value to the env:APP_NPM_AUTH variable in your p.sh project.
env:APP_NPM_NAMESPACE: The namespace of the packages in your private registry, eg @mynamespace.

Building and Deploying

Continuous Integration

The default provisioning script will configure platform.sh to build pull requests, so that every PR to your repository will be deployed to its own environment. Be aware of the following:

It is easy to reach your quota of development environments with this enabled, so use cautiously. One way to limit environment use is to create draft pull requests, as these are not deployed.
Edit environments for pull requests are currently only supported on GitHub repos -- and pushing changes from the edit environment is not supported on cross repository pull request(e.g. PR's source branch from fork).
Changes pushed to code outside the /edit directory will not automatically be deployed to the edit environment. You must manually update the edit environment as described under Pushing Changes below.
Pull request environments will be automatically deleted when the PR is merged or declined.
If you manually delete a PR environment, it will not be recreated when the PR is updated.
PR environments are named simply pr-{pr#} (eg pr-123). You can easily run platform cli commands against them using the -e pr-xxx option.
A link to the p.sh environment will be posted to the PR:
- GitHub: Expand the "Show All Checks" link next to the section on the "Conversations" tab, and click the "details" link next to the platform.sh build.

Manual Deployments

Pre-requisites

Access to a platform.sh project.
The platform.sh cli

Local setup

Obtain the project key of the project you wish to deploy: see The platform.sh project key, above.
Connect your local repository to the correct platform.sh remote. From within the repository root:
```
platform project:set-remote {project id}
```

Initial deployment of a new branch

Ensure you are on the correct branch locally.
Push the branch to GitHub.
```
git push origin <branch>
```
Execute
```
platform env:activate
```
Note - you may have to wait a few moments after pushing the branch to GitHub before activating the environment, in order to allow the branch to sync to p.sh. If, when you try to activate, you are asked for an "Environment ID", wait a bit and try again.
The public URL of the new environment will be printed to the console.
You can display (and open) the public URLs for your site by checking out the corresponding branch and executing platform url.

Basic Authentication

Note that basic authentication may be configured for your environment by default, and this may prevent access via your browser. To verify, use the platform cli:

platform env:http-access

You can also use this command to enable or disable authentication, and to add/remove credentials.

platform help env:http-access

to learn more.

Pushing changes

Once a new branch is created, changes pushed to GitHub will be automatically deployed to the static site on platform.sh. You can run platform activity:log to see the current build status, or visit console.platform.sh, locate your build, and click "View Logs".

Changes are not automatically deployed to an edit environment; you must manually trigger an update of the edit environment by executing:

platform ssh -e <env-id> 'bash platform.sh deploy'

You may omit the "-e " if you have the active branch checked out locally.

Deleting an environment

The platform.sh environment will be deleted when you remove the corresponding branch from GitHub. Please delete obsolete branches.

You can also remove an environment without deleting your branch by checking out the branch locally and executing platform env:delete -y.

Merging to main

When you merge a feature branch to main, the updated main branch will be automatically deployed to the static environment on platform.sh. To deploy changes to the edit environment, you must follow the same process as in Pushing Changes above.

Handling Redirects with Routes

Overview

In HTTP, URL redirecting is a technique to forward one URL to a different URL. It is commonly used for handling cases like URL shortening, preventing broken links when pages removed, pointing multiple domain addresses to a single URL address, etc. It is also critical to preserve page SEO value when there are URL changes.

Redirection can be implemented on a client page with Refresh Meta Tag or JavaScript, but the preferred way is to manage redirect rules with server configuration.

You can configure redirects on Platform.sh with route yaml in project environments. A route describes how an incoming HTTP request is processed by Platform.sh, which includes URL redirect. The routes are defined inside .platform/routes.yaml file.

An example of redirect using routes.yaml:

"https://www.{default}/":
  type: redirect
  to: "https://my-host.{default}/"

Here, the URL https://www.example.com/ will be redirected to https://my-host.example.com/

Whole-route vs Partial redirects

Platform.sh offers two different ways to implement redirect rules, Whole-route redirects and Partial redirects

Whole-route redirects on host level. A typical use case for this kind of route is adding or removing a www. prefix to domain,
.platform/routes.yaml
```
https://{default}/:
  type: redirect
  to: https://www.{default}/
```
Here, https://example.com/ will be redirected to https://www.example.com/. This approach can be used to redirect vanity domains to their destination URLs.
Partial redirects allows redirect rules to be added to existing routes,
.platform/routes.yaml
```
    https://{default}/:
      # [...]
      redirects:
        expires: 1d
        paths:
          '/from':
            to: 'https://example.com/'
            code: 301
```
Here, "https://[domain name]/from" will be redirected to https://www.example.com/.
Note:
- the default response code is 302, in order to use a different response code, mostly commonly 301, add "code: 301" as configurable option.
- "expires" param is optional, it specifies duration the redirect will be cached. Examples of valid values include 3600s, 1d, 2w, 3m.

Examples

file .platform/routes.yaml

Redirect path "/foo/bar" to a different site "https://example.com/".

https://{default}/:
  type: upstream
  redirects:
    paths:
      '/foo/bar':
        to: 'https://example.com/'

Using Regular Expression to redirect path that matches "/foo/(.*)/bar" pattern.
```
https://{default}/:
  type: upstream
  redirects:
    paths:
      '/foo/(.*)/bar':
        to: '/$1'
        regexp: true
```
In this case, path "/foo/cards/bar" will be redirected to "/cards".
Redirect with prefix.
```
https://{default}/:
  type: upstream
  redirects:
    paths:
      '/foo/bar':
        to: '/new'
        prefix: true
```
Path "/foo/bar" will be redirected to "/new". And path "/foo/bar/to/my/path" will be redirected to "/new/to/my/path" where both the path and all its children included. If "prefix" set to false, only "/foo/bar" will be redirected to "/new".

Carry over suffix path with append_suffix option.
```
  https://{default}/:
    type: upstream
    redirects:
      paths:
        '/foo/bar':
          to: 'https://{default}/new'
          append_suffix: false
```
If append_suffix is set to false, "/foo/bar/to/my/path" will be redirected to "/new". Otherwise, "/foo/bar/to/my/path" will be redirects to "/new/to/my/path". append_suffix is ignored if 'prefix' is false or 'regexp' is true.

HTTP vs HTTPS

Platform.sh recommends using HTTPS requests for all sites exclusively. Specifying HTTPS in route.yaml will automatically redirect any requests for an HTTP URL to HTTPS. While specifying only HTTP routes will result in duplicate HTTPS routes being created automatically, allowing the site to be served from both HTTP and HTTPS without redirects.

Although it is not recommended, HTTPS requests can be redirected to HTTP explicitly to serve the site over HTTP only using route.yaml:

"https://{default}/":
  type: redirect
  to: "http://{default}/"

Avoid redirect chains

A redirect chain is a series of redirects between the initial URL and the destination URL. The redirect chain could be built over time of development or due to a combination of redirect between different protocol, host name or trailing slash processing etc. Redirect chain causes page loss authority value in search result. It also increases page load time and decreases the overall quality of site.

In order to avoid redirect chains, pay attention on destination path protocol and host name. For example, if the site is running under https and host www, specify destination "to" in route.yaml as:

  to: "https://www.{default}/path/to/destination/"

The trailing slash should be appended to the configure item if platform environment adds trailing slash to url by default. see Platform.sh Documentation Redirects

Generate redirect rules for migration sites

BodilessJS Site Migration Tool package comes with a feature that allows user to export site redirection into file. See Tools/Migration for configuration.

User can apply these exported redirect rules to routers.yaml before deploying to platform.sh.

"https://{default}/":
    type: upstream
    upstream: "static:http"
    redirects:
      paths:
        /image/redirect.png:
          to: /image/placeholder.png
          code: 301
        /page2:
          to: /page3
          code: 301

Using Fastly CDN

Platform.sh integrates with Fastly via EZ platform for Fastly.

Obtain your Fastly Service ID & Key from Fastly.

Once Fastly Service ID & Key is obtained, these variables can be set at Main environment.

platform variable:create -e main --level environment env:HTTPCACHE_PURGE_TYPE --value 'fastly'
platform variable:create -e main --level environment env:FASTLY_SERVICE_ID --value 'YOUR_ID_HERE'
platform variable:create -e main --level environment env:FASTLY_KEY --value 'YOUR_ID_HERE'

Verify or Update your routes.yaml to enable caching for your site by setting enabled: true
```
    cache:
        enabled: true
        cookies: []
```
Verify or Update your .platform.app.yaml expiration time for your files.
```
web:
    locations:
        '/':
            expires: 6h  
```

Once completed, the main env deployed on Platform.sh should be on Fastly CDN. You may have to fine tune the expires setting for your static resources and set certain ones (ones identify not to change often such as font files) to longer to leverage browser caching.

Platform.sh References:

If there are issues or you need to troubleshoot, here are some good resources:

Checking Fastly Cache
curl -svo /dev/null -H "Fastly-Debug:1" www.example.com/index.html
Purging Fastly Cache
curl -X PURGE www.example.com/index.html

Environment specific HTML snippets

Note: this section applies only to hosting your static site on platform.sh, and is not required if you are using platform.sh only for edit environments.

Sometimes your site will need to know at build time whether it is in a production or development environment -- for example to set different endpoints for third party integrations. Platform.sh does not make the current branch available or allow you to expose environment level environment variables to your application during the build stage. To work around this limitation, Bodiless provides a mechanism to inject different html snippets depending on your environment type via Server Side Includes (SSI) mechanism.

Activate SSI

Activate SSI for your route(s) in your routes.yaml file. See: https://docs.platform.sh/configuration/routes/ssi.html
Use SSI_ENV environment variable to specify type of your environment. Default value is 'dev'.
Ensure ssi configs are loaded to psh container and set SSI_CONF_PATH environment variable to path to json file containing SSI configs.
Ensure your .platform.app.yaml contains invocation of generate-ssi-files.js node scripts. The script should be invoked during build and deploy phases. PSH phase (build or deploy) should be passed as an argument to the script.
Ensure the files of you app, that will be served by psh, contain SSI directives.
Ensure a writable volume is mounted to your app.

SSI config format

SSI configuration file should be in json format.

{
  key1: {
    pragma: "<!--# ssi data should go here -->",
    env1: {
      file: "key1.env1.html"
    }
    ...
    envN: {
      file: "key1.envN.html"
    }
  }
  ...
  keyN: {
    pragma: "<!--# ssi data should go here -->",
    ...
    env1: {
      file: "keyN.envN.html"
    }
    ...
    envN: {
      file: "keyN.envN.html"
    }
  }
}

How it works

during build phase, generate-ssi-files reads SSI configs and for each key it creates symlink from PLATFORM_DOCUMENT_ROOT/filename.html into APP_VOLUME/filename.html. Filename is generated based on key. There is an opportunity to improve this logic. We can read and parse pragma field, extract filename from it. But it makes the things more complicated and in addition, pragma may not have files at all.
during deploy phase, generate-ssi-files reads SSI configs and SSI_ENV and for each key it copies the file defined in conf.{key}.{env}.{file} to APP_VOLUME/filename.html that was created during build phase.

How to replace your site prod url with psh environment url in a public file

If you want to make urls in a particular public file match psh environment url, you can leverage psh-url-replacer node script. For instance, your site sitemap.xml, which is generated during build time, contains production urls and you want to replace the production url with psh environment url, to which your website is deployed to.

How it works

on psh build stage:

it moves your source file from public dir to a tmp directory
then it creates a symlink from a writable volume file to the source public file

on psh deploy stage:

it copies the file from the tmp directory to the writable volume file
then it replaces production url with psh environment url in the file

How to activate this feature

By default, the feature is activated for sitemap.xml and robots.txt. If you want to activate the feature for some other files or if you have custom installation of sitemap.xml or robots.txt, please follow the following steps:

ensure writable volume mounting is configured for your app
export environment variables and invoke psh-url-replacer in build section of your psh app .platform.app.yaml

hooks:
    build: |
        export PSH_URL_REPLACER_SRC_FILE=/path/to/your/src/public/file
        export PSH_URL_REPLACER_TMP_FILE=/path/to/a/tmp/file
        export PSH_URL_REPLACER_TARGET_FILE=/path/to/writable/volume/file
        node /path/to/psh-url-replacer.js build

export environment variables and invoke psh-url-replacer in deploy section of your psh app .platform.app.yaml

hooks:
    deploy: |
        export PSH_URL_REPLACER_TMP_FILE=/path/to/the/tmp/file/you/saved/during/build/phase
        export PSH_URL_REPLACER_TARGET_FILE=/path/to/writable/volume/file
        export PSH_URL_REPLACER_SRC_URL=https://your-site-production-url.com
        export PSH_URL_REPLACER_TARGET_URL=https://your-psh-env.url.site
        export PSH_URL_REPLACER_PROD_ENV='0' # set to '1' if you want to disable the replacement
        node /path/to/psh-url-replacer.js deploy

Known limitations and Troubleshooting

General

PR Branches and Feature branches created in GitHub will always inherit from main. This means that you must manually configure basic authentication for these branches if you want them protected from the public internet.
There is a 64-character limit on hostnames for TLS, and platform.sh uses 43 of them. Since hostnames are created based on branch names, and since the edit environment uses an additional 5 ("edit."), your branch names should be limited to a maximum of 16 characters to avoid certificate warnings.
When you run the provisioning script, a webhook is added to your GitHub repository. However, deleting the integration does not remove the webhook, you must do this manually.

Environment memory

On development environments, the edit site environment can use a large amount of memory when running, which might cause out-of-memory issues when building pages. This is caused by webpack's caching system, and there are two ways to circumvent the issue:

Increasing container memory

Use Large development containers to increase the total memory available to containers. This is the preferred way to solve this problem, as it's easier and faster. Note that this will increase costs.

Disable build cache

Disabling webpack's cache will drastically reduce memory consumption, but will also increase build times. This might be specially noticeable when doing simple operations like creating, cloning or moving pages.

To disable a site's cache, add cache: false to its webpack configuration. This is done in the gatsby-node.js file on the site root. Read Gatsby's documentation for an example, and refer to Webpacks's documentation if you want to understand how its caching system works.

Viewing Logs

Build, deploy and application logs for an environment are available using the platform cli. If you want logs for an environment other than the currently checked-out branch (e.g. for a pull request), you must use the -e flag. You can first get a list of all available environments by running

platform env:list

You can then use the identifier from the first column in the commands below. If you want logs from the environment associated with your current local branch, you can omit the -e flag.

Tail/print most recent build log (this now includes deploy log):
```
platform activity:log -e <env-id>
```
Note that you may have to wait a few moments after performing a git push in order for the new p.sh deployment to begin.
Print deploy logs for all builds to the edit environment:
```
platform log -e <env-id> -A edit deploy <--lines n>
```
(where n is the number of lines.)

View or tail application logs for the edit environment

platform log -e <env-id> -A edit app <--lines n> <--tail>

Alternatively, you can visit the platform.sh console and locate your build to view the build log (deployment and application logs are only available from the command line).
