Storybook Codemods

---

Storybook Codemods is a collection of codemod scripts written with JSCodeshift. It will help you migrate breaking changes & deprecations.

Installation

npm install jscodeshift
npm install @storybook/codemod

• @storybook/codemod is our collection of codemod scripts.
• jscodeshift is a tool we use to apply our codemods.

After running the migration commands, you can remove them from your package.json, if you added them.

How to run a codemod script

From the directory where you installed both jscodeshift and @storybook/codemod run:

Example:

./node_modules/.bin/jscodeshift -t ./node_modules/@storybook/codemod/dist/transforms/update-organisation-name.js . --ignore-pattern "node_modules|dist"

Explanation:

<jscodeShiftCommand> -t <transformFileLocation> <pathToSource> --ignore-pattern "<globPatternToIgnore>"

Transforms

update-organisation-name

Updates package names in imports to migrate to the new package names of storybook.

./node_modules/.bin/jscodeshift -t ./node_modules/@storybook/codemod/dist/transforms/update-organisation-name.js . --ignore-pattern "node_modules|dist"

There's a mapping of paths we replace but this example explains the gist of it:

Example:

import { storiesOf } from '@kadira/storybook';
import { linkTo } from '@kadira/storybook-addon-links';

Becomes

import { storiesOf } from '@storybook/react';
import { linkTo } from '@storybook/addon-links';

update-addon-info

Replaces the Info addon's deprecated addWithInfo API with the standard withInfo API.

./node_modules/.bin/jscodeshift -t ./node_modules/@storybook/codemod/dist/transforms/update-addon-info.js . --ignore-pattern "node_modules|dist"

Simple example:

storiesOf('Button').addWithInfo(
  'simple usage',
  'This is the basic usage of the button.',
  () => (
    <Button label="The Button" />
  )
)

Becomes

storiesOf('Button').add('simple usage', withInfo(
  'This is the basic usage of the button.'
)(() => (
  <Button label="The Button" />
)))

With options example:

storiesOf('Button').addWithInfo(
  'simple usage (disable source)',
  'This is the basic usage of the button.',
  () => (
    <Button label="The Button" />
  ),
  { source: false, inline: true }
)

Becomes

storiesOf('Button').add('simple usage (disable source)', withInfo({
  text: 'This is the basic usage of the button.',
  source: false,
  inline: true
})(() => (
  <Button label="The Button" />
)))
