Medic-conf NPM

Medic Project Configurer

Medic Conf is a command-line interface tool to manage and configure your apps built using the Core Framework of the Community Health Toolkit.

Requirements

nodejs 8 or later
python 2.7
or Docker

Installation

Docker

docker build -t medic-conf:v0 .
docker run medic-conf:v0
docker exec -it <container_name> /bin/bash

Ubuntu

npm install -g medic-conf
sudo python -m pip install git+https://github.com/medic/pyxform.git@medic-conf-1.17#egg=pyxform-medic

OSX

npm install -g medic-conf
pip install git+https://github.com/medic/pyxform.git@medic-conf-1.17#egg=pyxform-medic

Windows

As Administrator:

npm install -g medic-conf
python -m pip install git+https://github.com/medic/pyxform.git@medic-conf-1.17#egg=pyxform-medic --upgrade

Bash completion

To enable tab completion in bash, add the following to your .bashrc/.bash_profile:

eval "$(medic-conf --shell-completion=bash)"

Upgrading

To upgrade to the latest version

npm install -g medic-conf

Usage

medic-conf will upload the configuration from your current directory.

Specifying the server to configure

If you are using the default actionset, or performing any actions that require a CHT instance to function (e.g. upload-xyz or backup-xyz actions) you must specify the server you'd like to function against.

localhost

For developers, this is the instance defined in your COUCH_URL environment variable.

medic-conf --local

A specific Medic Mobile instance

For configuring against Medic Mobile-hosted instances.

medic-conf --instance=instance-name.dev

Username admin is used. A prompt is shown for entering password.

If a different username is required, add the --user switch:

--user user-name --instance=instance-name.dev

An arbitrary URL

medic-conf --url=https://username:password@example.com:12345

Into an archive to be uploaded later

medic-conf --archive

The resulting archive is consumable by Medic's API >v3.7 to create default configurations.

Perform specific action(s)

medic-conf <--archive|--local|--instance=instance-name|--url=url> <...action>

The list of available actions can be seen via medic-conf --help.

Perform actions for specific forms

medic-conf <--local|--instance=instance-name|--url=url> <...action> -- <...form>

Protecting against configuration overwriting

Added in v3.2.0

In order to avoid overwriting someone elses configuration medic-conf records the last uploaded configuration snapshot in the .snapshots directory. The remote.json file should be committed to your repository along with the associated configuration change. When uploading future configuration if medic-conf detects the snapshot doesn't match the configuration on the server you will be prompted to overwrite or cancel.

Currently supported

Settings

compile app settings from:
- tasks
- rules
- schedules
- contact-summary
- purge
app settings can also be defined in a more modular way by having the following files in app_settings folder: - base_settings.json - forms.json - schedules.json
backup app settings from server
upload app settings to server
upload resources to server
upload custom translations to the server
upload privacy policies to server
upload branding to server
upload partners to server

Forms

fetch from Google Drive and save locally as .xlsx
backup from server
delete all forms from server
delete specific form from server
upload all app or contact forms to server
upload specified app or contact forms to server

Managing data and images

convert CSV files with contacts and reports to JSON docs
move contacts by downloading and making the changes locally first
upload JSON files as docs on instance
compress PNGs and SVGs in the current directory and its subdirectories

Editing contacts across the hierarchy.

To edit existing couchdb documents, create a CSV file that contains the id's of the document you wish to update, and the columns of the document attribute(s) you wish to add/edit. By default, values are parsed as strings. To parse a CSV column as a JSON type, refer to the Property Types section to see how you can parse the values to different types. Also refer to the Excluded Columns section to see how to exclude column(s) from being added to the docs.

Parameter	Description	Required
column(s)	Comma delimited list of columns you wish to add/edit. If this is not specified all columns will be added.	No
docDirectoryPath	This action outputs files to local disk at this destination	No. Default `json-docs`
file(s)	Comma delimited list of files you wish to process using edit-contacts. By default, contact.csv is searched for in the current directory and processed.	No.

Example

Create a contact.csv file with your columns in the csv folder in your current path. The documentID column is a requirement. (The documentID column contains the document IDs to be fetched from couchdb.)

documentID	is_in_emnch:bool
documentID1	false
documentID2	false
documentID3	true

Use the following command to download and edit the documents:

medic-conf --instance=*instance* edit-contacts -- --column=*is_in_emnch* --docDirectoryPath=*my_folder*

Then upload the edited documents using the upload-docs command.

Project layout

This tool expects a project to be structured as follows:

example-project/
	.eslintrc
	app_settings.json
	contact-summary.js
	privacy-policies.json
	privacy-policies/
	    language1.html
	    …
	purge.js
	resources.json
	resources/
		icon-one.png
		…
	targets.js
	tasks.js
	task-schedules.json
	forms/
		app/
			my_project_form.xlsx
			my_project_form.xml
			my_project_form.properties.json
			my_project_form-media/
				[extra files]
				…
		contact/
			person-create.xlsx
			person-create.xml
			person-create-media/
				[extra files]
				…
		…
		…
	translations/
		messages-xx.properties
		…

If you are starting from scratch you can initialise the file layout using the initialise-project-layout action:

medic-conf initialise-project-layout

Derived configs

Configuration can be inherited from another project, and then modified. This allows the app_settings.json and contained files (task-schedules.json, targets.json etc.) to be imported, and then modified.

To achieve this, create a file called settings.inherit.json in your project's root directory with the following format:

{
	"inherit": "../path/to/other/project",
	"replace": {
		"keys.to.replace": "value-to-replace-it-with"
	},
	"merge": {
		"complex.objects": {
			"will_be_merged": true
		}
	},
	"delete": [
		"all.keys.listed.here",
		"will.be.deleted"
	],
	"filter": {
		"object.at.this.key": [
			"will",
			"keep",
			"only",
			"these",
			"properties"
		]
	}
}

Fetching logs

Fetch logs from a CHT v2.x production server.

This is a standalone command installed alongside medic-conf. For usage information, run medic-logs --help.

Usage

medic-logs <instance-name> <log-types...>

Accepted log types:

api
couchdb
gardener
nginx
sentinel

Development

To develop a new action or improve an existing one, check the "Actions" doc.

Testing

Execute npm test to run static analysis checks and the test suite.

Executing your local branch

Clone the project locally
Make changes to medic-conf or checkout a branch for testing
Test changes
1. To test CLI changes locally you can run node <project_dir>/src/bin/medic-conf.js. This will run as if you installed via npm.
2. To test changes that are imported in code run npm install <project_dir> to use the local version of medic-conf.

Releasing

Create a pull request with prep for the new release. This should contain changes to release notes if required and anything else that needs to be done. As commit messages should be clear and readable for every change, release-notes.md does not need to be updated for every single change. Instead, it should include information about significant changes, breaking changes, changes to interfaces, changes in behavior, new feature details, etc.
Get the pull request reviewed and approved
Run npm version patch, npm version minor, or npm version major as appropriate. This will:
- Update versions in package.json and package-lock.json
- Commit those changes locally and tag that commit with the new version
Run npm publish to publish the new tag to npm
git push && git push --tags to push the npm generated commit and tag up to your pre-approved pull request
Merge the pull request back into master
Announce the release on the CHT forum, under the "Product - Releases" category.

Releasing betas

Checkout master
Run npm version --no-git-tag-version <major>.<minor>.<patch>-beta.1. This will only update the versions in package.json and package-lock.json. It will not create a git tag and not create an associated commit.
Run npm publish --tag beta. This will publish your beta tag to npm's beta channel.

To install from the beta channel, run npm install medic-conf@beta.
