Quick steps ᐞ

There are a few quick steps below on what you need to do to update the application package dependencies.

1. Get bash to the container with make bash command

2. Use ng update to check Angular core package updates and follow the instructions of this tool to update these packages

3. Update rest of the packages, with one of the following commands:

   1. Use make update command to use interactive Yarn 4 update command to update all the packages.
   2. Use ncu to list remaining packages that can be updated. Then you can
      • Change the versions to package.json file and restart the application container - this will trigger yarn to install new versions of those packages and also updates yarn.lock file properly.
      • Or just use ncu -u to automatically update all of those packages and restart the application container.
   3. Run command yarn up <package>@<version> which will update both package.json and yarn.lock. After doing this for all needed packages, restart the application container.

4. Re-run install with lockfile validation:

   yarn install --immutable
   

5. Test that the application works.

6. Profit ¯\_(ツ)_/¯

Yarn 4 notes ᐞ

This repository is pinned to Yarn 4 via packageManager in package.json and the project-managed release under .yarn/releases/.

When working in Docker (make bash) or Dev Containers, run yarn commands from the project root so the pinned Yarn version is used.

Update Yarn itself ᐞ

Use these steps when you want to update Yarn to the latest stable version for this repository.

1. Open shell inside the running container:

   make bash
   

2. Update Yarn release used by this project:

   yarn set version stable
   yarn --version
   

3. Refresh lockfile/install metadata and validate:

   yarn install --immutable
   

4. Commit changed Yarn files (typically package.json, .yarnrc.yml, .yarn/releases/*, and sometimes yarn.lock).

Major version update ᐞ

When there is a Major version update (eg. 12.x.y to 13.0.0) within Angular we need to check proper instructions from official Angular Update Guide.

Other updates ᐞ

From time to time it's a good idea to update library dependencies as well.

Use one of the following commands depending on your goal:

yarn up -i            # interactive updates
yarn up <package>     # update one package
yarn up               # update according to semver ranges
yarn install --immutable
