# `typescript-plugin-styled-components`
This is a TypeScript transformer that improves development experience of [`styled-components`](https://www.styled-components.com/).
The main purpose is to provide compile-time information of creates styled components, such as names of these components, for the run-time, allowing to operate with proper names of such the components.
The plugin was mostly inspired by great Babel's plugin [`babel-plugin-styled-components`](https://github.com/styled-components/babel-plugin-styled-components) and partially provides similar functionality for TypeScript users.
If you like it, consider [](https://www.buymeacoffee.com/igorbek)
Note: This transformer will be useful to you only when you are transpiling your TS code using actual TS compiler, like `tsc` `ts-loader` or `awesome-typescript-loader`. If your TS code is transpiled using [`babel-plugin-transform-typescript`](https://babeljs.io/docs/en/babel-plugin-transform-typescript), you should use [`babel-plugin-styled-components`](https://github.com/styled-components/babel-plugin-styled-components) instead.
# Installation
The following command adds the packages to the project as a development-time dependency:
yarn add typescript-plugin-styled-components --dev

# Integration with `Webpack`
This section describes how to integrate the plugin into the build/bundling process driven by [**Webpack**](https://webpack.js.org/) and its TypeScript loaders.
There are two popular TypeScript loaders that support specifying custom transformers:
- [**awesome-typescript-loader**](https://github.com/s-panferov/awesome-typescript-loader), supports custom transformers since v3.1.3
- [**ts-loader**](https://github.com/TypeStrong/ts-loader), supports custom transformers since v2.2.0
Both loaders use the same setting `getCustomTransformers` which is an optional function that returns `{ before?: Transformer[], after?: Transformer[] }`.
In order to inject the transformer into compilation, add it to `before` transformers array, like: `{ before: [styledComponentsTransformer] }`.
## `awesome-typescript-loader`
In the `webpack.config.js` file in the section where **awesome-typescript-loader** is configured as a loader:
```js
// 1. import default from the plugin module
const createStyledComponentsTransformer = require('typescript-plugin-styled-components').default;
// 2. create a transformer;
// the factory additionally accepts an options object which described below
const styledComponentsTransformer = createStyledComponentsTransformer();
// 3. add getCustomTransformer method to the loader config
var config = {
...
module: {
rules: [
{
test: /\.tsx?$/,
loader: 'awesome-typescript-loader',
options: {
... // other loader's options
getCustomTransformers: () => ({ before: [styledComponentsTransformer] })
}
}
]
}
...
};
```
Please note, that in the development mode, `awesome-typescript-loader` uses multiple separate processes to speed up compilation. In that mode the above configuration cannot work because functions, which `getCustomTransformers` is, are not transferrable between processes.
To solve this please refer to [Forked process configuration](#forked-process-configuration) section.
## `ts-loader`
In the `webpack.config.js` file in the section where **ts-loader** is configured as a loader:
```js
// 1. import default from the plugin module
const createStyledComponentsTransformer = require('typescript-plugin-styled-components').default;
// 2. create a transformer;
// the factory additionally accepts an options object which described below
const styledComponentsTransformer = createStyledComponentsTransformer();
// 3. add getCustomTransformer method to the loader config
var config = {
...
module: {
rules: [
{
test: /\.tsx?$/,
loader: 'ts-loader',
options: {
... // other loader's options
getCustomTransformers: () => ({ before: [styledComponentsTransformer] })
}
}
]
}
...
};
```
Please note, when `awesome-typescript-loader` is used with `HappyPack` or `thread-loader`, they use multiple separate processes to speed up compilation. In that mode the above configuration cannot work because functions, which `getCustomTransformers` is, are not transferrable between processes.
To solve this please refer to [Forked process configuration](#forked-process-configuration) section.
## Forked process configuration
To configure the transformer for development mode in `awesome-typescript-loader` or `ts-loader` with `HappyPack` or `thread-loader`, you need to make `getCustomTransformers` a resolvable module name instead of the function. Since the configuration is very similar, here's an example:
### 1. Move `styledComponentsTransformer` into a separate file
Let's assume it is in the same folder as your `webpack.config` and has name `webpack.ts-transformers.js`:
```js
// 1. import default from the plugin module
const createStyledComponentsTransformer = require('typescript-plugin-styled-components').default;
// 2. create a transformer;
// the factory additionally accepts an options object which described below
const styledComponentsTransformer = createStyledComponentsTransformer();
// 3. create getCustomTransformer function
const getCustomTransformers = () => ({ before: [styledComponentsTransformer] });
// 4. export getCustomTransformers
module.exports = getCustomTransformers;
```
### 2. Change the loader's options to point to that file instead of explicit function
```diff
-const createStyledComponentsTransformer = require('typescript-plugin-styled-components').default;
-const styledComponentsTransformer = createStyledComponentsTransformer();
options: {
... // other loader's options
- getCustomTransformers: () => ({ before: [styledComponentsTransformer] })
+ getCustomTransformers: path.join(__dirname, './webpack.ts-transformers.js')
}
```
# Integration with `Rollup`
This section describes how to integrate the plugin into the build/bundling process driven by [**Rollup**](https://rollupjs.org/guide/en/) and its TypeScript loader - [**rollup-plugin-typescript2**](https://github.com/Igorbek/typescript-plugin-styled-components).
In the `rollup.config.js` file in the section where **rollup-plugin-typescript2** is configured as a loader:
```js
// 1. import default from the plugin module
const createStyledComponentsTransformer = require('typescript-plugin-styled-components').default;
// 2. create a transformer;
// the factory additionally accepts an options object which described below
const styledComponentsTransformer = createStyledComponentsTransformer();
// 3. add getCustomTransformer method to the loader config
var config = {
...
plugins: [
rollupTypescript({
...
transformers: [
() => ({
before: [styledComponentsTransformer],
}),
],
}),
...
],
...
};
```
# TypeScript compiler (CLI)
TypeScript command line compiler tool (`tsc`) does not support using of pluggable modules and transformers.
For that reason there are other tools created that do support pluggable transformers. See [`ttypescript` compiler](#ttypescript-compiler) section.
# `ttypescript` compiler
The [`ttypescript` compiler](https://github.com/cevek/ttypescript) is a CLI tool that allows to use TypeScript compiler with pluggable transformers.
To use the transformer with that tool you can configure it by updating `tsconfig.json` the following way:
```js
{
"compilerOptions": {
"plugins": [
{
"transform": "typescript-plugin-styled-components",
"type": "config",
// other typescript-plugin-styled-components options can be added here
"minify": true,
"ssr": true
}
]
}
}
```
# API
## `createTransformer`
```ts
function createTransformer(options?: Partial): TransformerFactory;
```
A factory that creates an instance of a TypeScript transformer (which is a factory itself).
It allows to optionally pass options that allow to tweak transformer's behavior. See `Options` for details.
## `Options`
```ts
interface Options {
getDisplayName(filename: string, bindingName: string | undefined): string | undefined;
identifiers: CustomStyledIdentifiers;
ssr: boolean;
displayName: boolean;
minify: boolean;
componentIdPrefix: string;
}
```
### `getDisplayName`
This method is used to determine component display name from filename and its binding name.
`filename` is the file name, relative to the project base directory, of the file where the styled component defined.
`bindingName` is the name that is used in the source code to bind the component. It can be `null` if the component was not bound or assigned.
Default strategy is to use `bindingName` if it's defined and use inference algorithm from `filename` otherwise.
Sample:
```js
function getStyledComponentDisplay(filename, bindingName) {
return bindingName || makePascalCase(filename);
}
```
### `ssr`
By adding a unique identifier to every styled component, this plugin avoids checksum mismatches
due to different class generation on the client and on the server.
This option allows to disable component id generation by setting it to `false`.
Default value is `true` which means that component id is being injected.
### `displayName`
This option enhances the attached CSS class name on each component with richer output
to help identify your components in the DOM without React DevTools.
It also adds allows you to see the component's `displayName` in React DevTools.
To disable `displayName` generation set this option to `false`
Default value is `true` which means that display name is being injected.
### `minify`
The option allows to turn on minification of inline styles used in styled components.
It is similar to [`babel-plugin-styled-components`](https://github.com/styled-components/babel-plugin-styled-components)'s same option.
The minification is not exactly the same and may produce slightly different results.
:warning: **Warning**: The minification is an experimental feature, please use with care.
Default value is `false` which means the minification is not being performed.
### `componentIdPrefix`
To avoid colisions when running more than one insance of typescript-plugin-styled-components at a time, you can add a componentIdPrefix by providing an arbitrary string to this option.
Default value is `''` which means that no namespacing will happen.
### `identifiers`
This option allows to customize identifiers used by `styled-components` API functions.
> **Warning**. By providing custom identifiers, predefined ones are not added automatically.
> Make sure you add standard APIs in case you meant to use them.
```ts
interface CustomStyledIdentifiers {
styled: string[];
attrs: string[];
keyframes: string[];
css: string[];
createGlobalStyle: string[];
extend: string[];
}
```
- `styled` - list of identifiers of `styled` API (default `['styled']`)
- `attrs` - list of identifiers of `attrs` API (default `['attrs']`)
- `keyframes` - list of identifiers of `keyframes` API (default `['keyframes']`)
- `css` - list of identifiers of `css` API (default `['css']`)
- `createGlobalStyle` - list of identifiers of `createGlobalStyle` API (default `['createGlobalStyle']`)
- `extend` - list of identifiers of `extend` API (default `[]`). Note this API has been deprecated in `styled-components` so starting from `1.5` this option by default has empty set, which means it does not recognize this API by default.
Example
```ts
const styledComponentsTransformer = createStyledComponentsTransformer({
identifiers: {
styled: ['styled', 'typedStyled'] // typedStyled is an additional identifier of styled API
}
});
```
# Notes
Technically, `typescript-plugin-styled-components` is not a TypeScript plugin, since it is only exposed as a TypeScript transformer.
