Release Notes

yeoman/generator

v4.1.0

Compare Source

• New --bail flag who'll exit the generator as soon as a conflict occurs.
• New generator#queueMethod() allows generator to programmatically schedule tasks on the queue. This can be useful for parents generator who're inherited by children generators to schedule some default tasks automatically. (not a very common use, but might be useful in some edge cases)

v4.0.2

Compare Source

• Fix bug with detection of binary files.

v4.0.1

Compare Source

v4.0.0

Compare Source

Breaking

• Officially supports Node >= 8 (dropped support for Node 6)
• Install methods will be run 1 time per set of arguments. Previously we'd only run them once no matter the arguments, this prevented use case like different npm settings for more complicated setup with different targets (server/browser) #​1108

v3.2.0

Compare Source

Added a new optional syntax to use composeWith:

this.composeWith({
    Generator: require('generator-x'),
    path: require.resolve('generator-x')
})

v3.1.1

Compare Source

Fix some issues with --force-install not being detected properly from the command line arguments.

v3.1.0

Compare Source

Add --force-install flag which will cause the generator to throw if the installation phase fail.

v3.0.0

Compare Source

Maintenance release with a few breaking change that shouldn't impact most users.

Breaking

• mem-fs-editor updated to latest release. A sub-dependency moved from node-glob to fast-glob, so some of the this.fs methods glob options will change.
• Install methods: npmInstall, bowerInstall, yarnInstall and installDependencies do not return promises anymore. This behavior was confusing and a major source of bugs. To handle actions after the install might've run (if user didn't specify --skip-install), use the end run loop phase.
• Renamed runInstall to scheduleInstallTask

New

• For users of the Yeoman API: generator.run() now returns a promise as well as taking a callback (the callback will keep working for the foreseeable future as we need to maintains backward compatibility with older generators)
