importmap-package-manager

importmap-package-manager adds package version management to importmap-rails via version ranges, similar to how version ranges can be specified in Gemfile (eg ~> 4.0).

This is for managing third-party libraries. For your own first-party code, that will still be managed in the normal ways via importmap-rails.

Installation

First, you'll need to have importmap-rails set up and configured properly for your application.

Once that's done, add this line to your application's Gemfile:

gem "importmap-package-manager"

And then execute:

$ bundle install

Finally, run this gem's installer:

$ bundle exec rails importmap_package_manager:install

Usage

1. Add packages to config/importmap_packages.yml under the imports key. See [#package-options] for more details. You'll also want to delete these from config/importmap.rb.
2. Run bundle exec rails importmap_package_manager:update to update config/importmap-packages-lock.rb
3. That's it! From here, your packages will automatically be available in the importmap and ready to be used.

Package options

Each import should be specified as a key/value pair. In the most simple case, the key is the package name and the value is the version constraint. For example:

imports:
  lodash: "~> 4.0"

In this case, importmap-package-manager will install the latest 4.0 version of lodash.

Packages can also be broken out into more detail, to provide more options:

imports:
  lodash/merge:
    package: "lodash"
    version: "~> 4.0.0"
    subpath: "./merge"

This would produce something like the following in your importmap: { "lodash/merge": "https://ga.jspm.io/npm:lodash@4.17.21/merge.js" }

In this case, the key is just a unique identifier. It isn't used at all.

The options that can be passed for each import are:

Option	Description
package	Package name, as listed in npmjs.com
version	Version number constraint, using ruby syntax
subpath	A subpath within the package to pin. This will be used in both the import name, and the path.

Development

After checking out the repo, run bundle install to install dependencies. Then, run rake spec to run the tests.

To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
