react-docgen-typescript-plugin

A webpack plugin to inject react typescript docgen information

Install

npm install --save-dev react-docgen-typescript-plugin
# or
yarn add -D react-docgen-typescript-plugin

Usage

NOTE: The TypeScript compiler options allowSyntheticDefaultImports and esModuleInterop will make react-docgen-typescript-plugin a lot harder! Turn them off for faster build times.

const ts = require('typescript');
const ReactDocgenTypescriptPlugin = require("react-docgen-typescript-plugin").default;

module.exports = {
  plugins: [
    // Will default to loading your root tsconfig.json
    new ReactDocgenTypescriptPlugin(),
    // or with a specific tsconfig
    new ReactDocgenTypescriptPlugin({ tsconfigPath: "./tsconfig.dev.json" }),
    // or with compiler options
    new ReactDocgenTypescriptPlugin({ compilerOptions: { jsx: ts.JsxEmit.Preserve } }),
  ],
};

Options

This plugins support all parser options from react-docgen-typescript and all of the following options

Option	Type	Description	Default
tsconfigPath	string	Specify the location of the `tsconfig.json` to use.	`null`
compilerOptions	object	Specify compiler options. Cannot be used with `tsconfigPath`	`null`
docgenCollectionName	string or null	Specify the docgen collection name to use. All docgen information will be collected into this global object. Set to `null` to disable.	`STORYBOOK_REACT_CLASSES`
setDisplayName	boolean	Set the components' display name. If you want to set display names yourself or are using another plugin to do this, you should disable this option.	`true`
typePropName	string	Specify the name of the property for docgen info prop type.	`type`
exclude	glob[]	Glob patterns to ignore and not generate docgen information for. (Great for ignoring large icon libraries)	`[]`
include	glob[]	Glob patterns to generate docgen information for	`['/.tsx']`

Debugging

If you want to see how this plugins is including and excluding modules set the DEBUG environment variable.

DEBUG=docgen:* - All logs
DEBUG=docgen:include - Included modules
DEBUG=docgen:exclude - Excluded modules
DEBUG=docgen:docs - Generated docs

DEBUG=docgen:* npm run storybook

Another great way of debugging your generated docs is to use a debugger statement in your component source file. If you turn off source maps you will be able to see the code that this package generates.
