Pinning and Versioning

  • Status: Completed

Pinning Plugins

We want to start pinning core plugins to cordova-lib. When a user using the cordova-cli runs the command cordova plugin add cordova-plugin-device, the version that is pinned in cordova-lib should be fetched from npm instead of fetching the latest tag.

This assumes:

  • user has not specified a version during add step. (cordova plugin add cordova-plugin-file@2.0.0)
  • user does not have a version specified in config.xml. (<plugin name="cordova-plugin-device" spec="2.0.0" />)

The user specified version will always trump the pinned cordova-lib plugin version.

I plan on pinning the plugins in the package.json of cordova-lib.

'cordovaPlugins' : {
'cordova-plugin-file':'~3.0.0',
'cordova-plugin-device':'~1.0.0'
}

I suggest using the same pinning strategy as we currently do for platforms. ~1.0.0 would grab version 1.0.0 or the highest patch releases. It is essentially equivalent to 1.0.x.These pinned versions should be reviewed and updated with each release of cordova-cli and cordova-lib.

Why Pin?

Cordova needs to do a better job at stability.

Currently, cordova-cli fetches the latest plugins from npm. When we release major updates for plugins, they may require newer versions of platforms and tools. When this happens, developers using older versions of platforms and tools will start to see engine tag failures when attempting to install the latest plugins. They will have to explicitly install older versions by running cordova plugin add cordova-plugin-file@2.0.0. This is useable but not ideal. Users will most likely get confused when they first see the engine failures.

Versioning

Each cordova version (cordova-cli/cordova-lib) will now always have pinned plugins and platforms. We will only tell users to update their tools and advise against updating platforms and plugins independently (unless they want to live on the edge or need those bug fixes asap). This cordova version will be the outwards facing version users will see.

cordova will still follow SemVer. Now, a major platform bump will be considered a major version bump for cordova. This will lead to a higher frequency of major cordova releases. We will try to mitigate this by trying to get platforms to release major updates around similar timelines, but this won't always be the case.

Plugin version updates will be handled on a case by case basis. Most plugin updates will only require a minor update to cordova.

Updating

Hopefully these new strategies will allow us to offer an improved updating workflow. The goal would be to have a cordova update command which would update the projects platforms and plugins based on what is pinned in cordova. A user would just have update their version of cordova and run the cordova update command on their project to be using the most up to date version of cordova in their projects.

Also, part of the updating workflow would be to better support cordova platform/plugin check and cordova outdated to see which plugins and platforms can be updated.
