# TSDX React w/ Storybook User Guide



## Commands



TSDX scaffolds your new library inside `/src`, and also sets up a [Parcel-based](https://parceljs.org) playground for it inside `/example`.



The recommended workflow is to run TSDX in one terminal:



```bash

pnpm start

```



This builds to `/dist` and runs the project in watch mode so any edits you save inside `src` causes a rebuild to `/dist`.



Then run either Storybook or the example playground:



### Storybook



Run inside another terminal:



```bash

pnpm storybook

```



This loads the stories from `./stories`.



> NOTE: Stories should reference the components as if using the library, similar to the example playground. This means importing from the root project directory. This has been aliased in the tsconfig and the storybook webpack config as a helper.



### Example



Then run the example inside another:



```bash

cd example

npm i # or pnpm to install dependencies

npm start # or pnpm start

```



The default example imports and live reloads whatever is in `/dist`, so if you are seeing an out of date component, make sure TSDX is running in watch mode like we recommend above. **No symlinking required**, we use [Parcel's aliasing](https://parceljs.org/module_resolution.html#aliases).



To do a one-off build, use `pnpm build`



To run tests, use `pnpm test`



## Configuration



Code quality is set up for you with `prettier`, `husky`, and `lint-staged`. Adjust the respective fields in `package.json` accordingly.



### Jest



Jest tests are set up to run with `pnpm test`



### Bundle analysis



Calculates the real cost of your library using [size-limit](https://github.com/ai/size-limit) with `npm run size` and visulize it with `npm run analyze`.



#### Setup Files



This is the folder structure we set up for you:



```txt

/example

  index.html

  index.tsx       # test your component here in a demo app

  package.json

  tsconfig.json

/src

  index.tsx       # EDIT THIS

/test

  blah.test.tsx   # EDIT THIS

/stories

  Thing.stories.tsx # EDIT THIS

/.storybook

  main.js

  preview.js

.gitignore

package.json

README.md         # EDIT THIS

tsconfig.json

```



#### React Testing Library



We do not set up `react-testing-library` for you yet, we welcome contributions and documentation on this.



### Rollup



TSDX uses [Rollup](https://rollupjs.org) as a bundler and generates multiple rollup configs for various module formats and build settings. See [Optimizations](#optimizations) for details.



### TypeScript



`tsconfig.json` is set up to interpret `dom` and `esnext` types, as well as `react` for `jsx`. Adjust according to your needs.



## Continuous Integration



### GitHub Actions



Two actions are added by default:



- `main` which installs deps w/ cache, lints, tests, and builds on all pushes against a Node and OS matrix

- `size` which comments cost comparison of your library on every pull request using [size-limit](https://github.com/ai/size-limit)



## Optimizations



Please see the main `tsdx` [optimizations docs](https://github.com/palmerhq/tsdx#optimizations). In particular, know that you can take advantage of development-only optimizations:



```js

// ./types/index.d.ts

declare var __DEV__: boolean;



// inside your code...

if (__DEV__) {

  console.log('foo');

}

```



You can also choose to install and use [invariant](https://github.com/palmerhq/tsdx#invariant) and [warning](https://github.com/palmerhq/tsdx#warning) functions.



## Module Formats



CJS, ESModules, and UMD module formats are supported.



The appropriate paths are configured in `package.json` and `dist/index.js` accordingly. Please report if any issues are found.



## Deploying the Example Playground



The Playground is just a simple [Parcel](https://parceljs.org) app, you can deploy it anywhere you would normally deploy that. Here are some guidelines for **manually** deploying with the Netlify CLI (`npm i -g netlify-cli`):



```bash

cd example # if not already in the example folder

npm run build # builds to dist

netlify deploy # deploy the dist folder

```



Alternatively, if you already have a git repo connected, you can set up continuous deployment with Netlify:



```bash

netlify init

# build command: yarn build && cd example && yarn && yarn build

# directory to deploy: example/dist

# pick yes for netlify.toml

```



## Named Exports



Per Palmer Group guidelines, [always use named exports.](https://github.com/palmerhq/typescript#exports) Code split inside your React app instead of your React library.



## Including Styles



There are many ways to ship styles, including with CSS-in-JS. TSDX has no opinion on this, configure how you like.



For vanilla CSS, you can include it at the root directory and add it to the `files` section in your `package.json`, so that it can be imported separately by your users and run through their bundler's loader.



## Publishing to NPM



We recommend using [np](https://github.com/sindresorhus/np).



## Usage with Lerna



When creating a new package with TSDX within a project set up with Lerna, you might encounter a `Cannot resolve dependency` error when trying to run the `example` project. To fix that you will need to make changes to the `package.json` file _inside the `example` directory_.



The problem is that due to the nature of how dependencies are installed in Lerna projects, the aliases in the example project's `package.json` might not point to the right place, as those dependencies might have been installed in the root of your Lerna project.



Change the `alias` to point to where those packages are actually installed. This depends on the directory structure of your Lerna project, so the actual path might be different from the diff below.



```diff

   "alias": {

-    "react": "../node_modules/react",

-    "react-dom": "../node_modules/react-dom"

+    "react": "../../../node_modules/react",

+    "react-dom": "../../../node_modules/react-dom"

   },

```



An alternative to fixing this problem would be to remove aliases altogether and define the dependencies referenced as aliases as dev dependencies instead. [However, that might cause other problems.](https://github.com/palmerhq/tsdx/issues/64)
