remove-binding

Ember 2.7 introduced a new deprecation to EmberBinding. This codemod aims to convert all existing uses of fooBinding: 'path.to.property' to foo: alias('path.to.property') and if the current file does not have the alias import the following line will also be added import { alias } from '@ember/object/computed';

Usage

npx ember2-x-codemods remove-binding path/of/files/ or/some**/*glob.js

# or

yarn global add ember2-x-codemods
ember2-x-codemods remove-binding path/of/files/ or/some**/*glob.js

Local Usage

node ./bin/cli.js remove-binding path/of/files/ or/some**/*glob.js
