@ember-data/codemods

Codemods for EmberData paradigms.

Usage

List all available codemod commands

npx @ember-data/codemods apply --help

The available codemods will be listed under the "Commands" heading.

Run a codemod

npx @ember-data/codemods apply <codemod-name> [codemod-options] <target-glob-pattern...>

For example:

npx @ember-data/codemods apply legacy-compat-builders ./app/**/*.{js,ts}

Codemod options

To list the available options for a particular codemod, you can run:

npx @ember-data/codemods apply <codemod-name> --help

Codemods

legacy-compat-builders

npx @ember-data/codemods apply legacy-compat-builders --help
Usage: @ember-data/codemods apply legacy-compat-builders [options] <target-glob-pattern...>

Updates legacy store methods to use `store.request` and `@ember-data/legacy-compat/builders` instead.

Arguments:
  target-glob-pattern                    Path to files or glob pattern. If using glob pattern, wrap in single
                                         quotes.

Options:
  -d, --dry                              dry run (no changes are made to files) (default: false)
  -v, --verbose <level>                  Show more information about the transform process (choices: "0", "1",
                                         "2", default: "0")
  -l, --log-file [path]                  Write logs to a file. If option is set but no path is provided, logs are
                                         written to ember-data-codemods.log
  -i, --ignore <ignore-glob-pattern...>  Ignores the given file or glob pattern. If using glob pattern, wrap in
                                         single quotes.
  --store-names <store-name...>          Identifier name associated with the store. If overriding, it is
                                         recommended that you include 'store' in your list. (default: ["store"])
  --method, --methods <method-name...>   Method name(s) to transform. By default, will transform all methods.
                                         (choices: "findAll", "findRecord", "query", "queryRecord", "saveRecord")
  -h, --help                             display help for command

Examples

findAll

// before
const posts = await store.findAll<Post>('post');

// after
import { findAll } from '@ember-data/legacy-compat/builders';
const { content: posts } = await store.request<Post[]>(findAll<Post>('post'));

findRecord

// before
const post = await store.findRecord<Post>({ type: 'post', id: '1' });

// after
import { findRecord } from '@ember-data/legacy-compat/builders';
const { content: post } = await store.request<Post>(findRecord<Post>({ type: 'post', id: '1' }));

NOTE: This codemod will not transform store.findRecord calls with a 'preload' option set. This option is not supported by the legacy compat builders.

query

// before
const posts = await store.query<Post>('post', { id: '1' });

// after
import { query } from '@ember-data/legacy-compat/builders';
const { content: posts } = await store.request<Post[]>(query<Post>('post', { id: '1' }));

queryRecord

// before
const post = await store.queryRecord<Post>('post', { id: '1' });

// after
import { queryRecord } from '@ember-data/legacy-compat/builders';
const { content: post } = await store.request<Post>(queryRecord<Post>('post', { id: '1' }));

saveRecord

// before
const post = store.createRecord<Post>('post', { name: 'Krystan rules, you drool' });
const savedPostWithGeneric = await store.saveRecord<Post>(post);
const savedPostNoGeneric = await store.saveRecord(post);

// after
import { saveRecord } from '@ember-data/legacy-compat/builders';
const post = store.createRecord<Post>('post', { name: 'Krystan rules, you drool' });
const { content: savedPostWithGeneric } = await store.request<Post>(saveRecord(post));
const { content: savedPostNoGeneric } = await store.request(saveRecord(post));

Handling of await

Calls to legacy store methods that are not currently awaited will not be transformed. In order to provide feature parity with the legacy method, we need to access the content property from Future returned by store.request. In order to do this, we need to await store.request, but we can't safely add await with a codemod as we don't know if the consuming code will be able to handle the change.

There is one exception to this rule. In the case where a route's model hook returns a call to a legacy store method, the codemod will transform the legacy store method and will add the await keyword.

Caveats

GJS and GTS files are not currently supported. PRs welcome! 🧡
