# ember-computed-decorators-codemod

This codemod uses [`jscodeshift`](https://github.com/facebook/jscodeshift) to update an Ember application using [`ember-computed-decorators`](https://github.com/ember-decorators/ember-decorators/tree/v0.3.0) to [`ember-decorators`](https://github.com/ember-decorators/ember-decorators). This update allows applications to migrate to babel 6 and beyond without having to rely on the [`babel-plugin-transform-decorators-legacy`](https://github.com/loganfsmyth/babel-plugin-transform-decorators-legacy).

For example, it will rewrite code that looks like this:

```js

import Ember from 'ember';

import computed, { alias } from 'ember-computed-decorators';

const { Component } = Ember;

export default Component.extend({

  @alias('fullName') myFullName,

  @computed('firstName', 'lastName')

  fullName() {

    return `${this.get('firstName')} + ${this.get('lastName')}`

  }

})

```

Into this:

```js

import Ember from 'ember';

import { computed } from '@ember-decorators/object';

import { alias } from '@ember-decorators/object/computed';

const { Component } = Ember;

export default Component.extend({

  @alias('fullName') myFullName,

  @computed('firstName', 'lastName')

  fullName() {

    return `${this.get('firstName')} + ${this.get('lastName')}`

  }

})

```

## Usage

**WARNING**: `jscodeshift`, and thus this codemod, **edit your files in place**.

It does not make a copy. Make sure your code is checked into a source control

repository like Git and that you have no outstanding changes to commit before

running this tool.

The simplest way to use the codemod is like this:

```sh

yarn global add ember-computed-decorators-codemod

cd my-ember-app

ember-computed-decorators-codemod

```

https://github.com/ember-decorators/auto-computed

### Running Tests

```sh

yarn test // run all tests once

yarn test -- --watchAll // continuously run tests

```

Tests for this codemod work by comparing a paired input and output file in the `__testfixtures__` directory.  Pre-transform files should be of format `.input.js`, expected output after the transform should be named `.output.js`. Files must use the same `` in their names so they can be compared.
