ember-cli-update

ember-cli-update

Update Ember CLI Ember.js apps and addons

You can run this either as a global executable available to all projects or an Ember CLI command in a single project.

Installation

As a global executable:

npm install -g ember-cli-update

As an Ember CLI command:

ember install ember-cli-update

(You must commit the change to package.json before running the update command or else you get an error.)

Usage

Make sure your git working directory is clean before updating.

Inside your project directory, if you installed globally run

ember-cli-update

or if you installed as a command run

ember update

This will update your app or addon to the latest Ember CLI version. It does this by grabbing your current installed Ember CLI version and looking up the latest version, then applying a diff of the changes needed to your project. Your project files will only get modified if they were changed in the by Ember CLI between versions, and it will only change the section necessary, not the entire file.

This is different from the existing ember init command. That command tries to reset your project back to a brand new project. It removes all your changes and additions.

You will probably encounter merge conflicts, in which your system's git merge tool will run.

Options

--to	Update to a version that isn't latest	String	"2.14.1" "~2.15" "latest" "beta"	"latest"

Hints

Need help using git mergetool? Here are some starting points:

• https://git-scm.com/docs/git-mergetool
• https://gist.github.com/karenyyng/f19ff75c60f18b4b8149

If you made a mistake during the update/conflict resolution, run these commands to undo everything and get you back to before the update:

git reset --hard
git clean -f

If you notice ".orig" files lying around after a merge and don't want that behavior, run git config mergetool.keepBackup false.

To avoid being prompted "Hit return to start merge resolution tool (vimdiff):" for every conflict, set a merge tool like git config merge.tool "vimdiff".
