CLI for deploying FT Graphics projects

  > g-deploy [FLAGS...] <dir>

  <dir> - Path to the directory you want to upload (default: ./dist/client)

  Settings Presets
  These provide default values for bucket, project, branch, etc
    --preview - For deploying to our okta-protected preview environment
        expands to: --bucket djd-ig-preview --url-base preview
    --live - To make pages available in ig-router
        expands to: --bucket djd-ig-live --url-base v3 --branch HEAD --tag HEAD --write-versions-json

  ────────────────────────────────────────────────────────────────────
  The remaining flags are optional when this command is run from a typical FT
  Graphics project repo in CI.

  AWS settings
  Authentication should follow the standard AWS env vars or profile
    --bucket - S3 bucket to upload to, defaults to BUCKET_NAME env
    --public-read - Whether to apply a public-read ACL to the files uploaded
    --aws-region - AWS region the bucket lives in, defaults to AWS_REGION env or 'eu-west-1'

  Upload settings
  If not provided, these are deduced from the git status in the CWD.
    --project - Name of the project, defaults to current git repo (e.g. ft-interactive/some-story)
    --branch - Name of the branch you are deploying, defaults to current in git
    --tag - Tagged version to deploy
    --url-base - First component of the URL to upload to, defaults to 'v2'

  Other
    --help - show this help and exit
    --get-branch-url - instead of deploying, just print the URL it would deploy to
    --get-tag-url - as above, but get the tag-specific URL
    --confirm - skip the confirmation dialogue when deploying
    --write-versions-json - write a VERSIONS.json file at the project base containing every version number

JavaScript API

The most straightforward way:

import deploy from "@financial-times/g-deploy";

deploy(options).then((baseURLs) => {
  console.log("uploaded to:", baseURLs);
});

For more fine-grained control:

import { Deployer } from "@financial-times/g-deploy";

const deployer = new Deployer(options);

deployer.execute().then((baseURLs) => {
  console.log("uploaded to:", baseURLs);
});

The JavaScript API does not do any git-sniffing or use any environment variables to configure the deployment – you must pass in all required options manually. See the Deployer class source for the full options.

Development

Clone this repo and run yarn to install dependencies.

Run yarn build -- --watch and yarn test -- --watch in separate terminal tabs while developing. (The first one watches src and builds to dist. The second one runs ava tests in dist.)

Publishing to NPM

After you merge a pull request with a new feature, you should deploy it to NPM. To do so:

1. Make sure you're on main: git checkout main
2. Run npm version [major|minor|patch] to increment the version based on the type of changes in this release. We use Semantic Versioning to increment versions:

• Breaking (non-backwards-compatible) changes should be a major release
• New features (that are backwards-compatible) should be minor
• Bug fixes should be a patch
• Alternatively, you can use npm version vX.X.X to set the version yourself.

3. Run git push --follow-tags to push the new version to GitHub, which will trigger the CircleCI pipeline that publishes the new version on NPM.

Pre-release ("canary") versions

If you'd like to release a pre-release version (e.g. to test or gradually roll out a new feature), you can create a new version like npm version v1.0.0-canary.0. The version number should represent the ultimate release this change will land in, while the final 0 can be incremented to make subsequent prerelease builds.

NPM can also generate this automatically for you, with npm version pre[major|minor|patch] --preid canary.
