# React to TSX Code

> A toolkit provide some codemod scripts based on [jscodeshift](https://github.com/facebook/jscodeshift) to migrating react code base to typesceipt.
## Getting Started
> **NOTE** Please make sure a stable and modern verison of node and npm packages installed!
```bash
git clone $this-repo
yarn install
# or npm install
```
## Usage
All npm scripts can be run in `jscodeshift's dry` mode, which will never really change the files' content.
```bash
jscodeshift -t ./transforms/$some-provided-codemod.js $react-code-base-path --extension js --parser babylon
```
If you want to rename all js/jsx files to tsx/ts files, a simple rename file is provied to do this job.
```bash
npm run rename $code-base-path js tsx
```
### add-import.js
Add a import statement to each file match the path pattern specified;
### react-to-tsx.js
Add type annotaions to react composite components based on exsiting propTypes defination, turn from
```jsx
...
class Counter extends Component {
static propTypes = {
active: PropTypes.bool,
name: PropTypes.string,
count: PropTypes.number,
unit: PropTypes.node,
lowerLimit: PropTypes.number,
upperLimit: PropTypes.number,
onCountChange: PropTypes.func,
};
...
}
...
```
to:
```jsx
...
type CounterState = {};
interface CounterProps extends BaseProps {
active?: boolean,
name?: string,
count?: number,
unit?: any,
lowerLimit?: number,
upperLimit?: number,
onCountChange?: any,
}
class Counter extends Component {
static propTypes = {
active: PropTypes.bool,
name: PropTypes.string,
count: PropTypes.number,
unit: PropTypes.node,
lowerLimit: PropTypes.number,
upperLimit: PropTypes.number,
onCountChange: PropTypes.func,
};
...
}
...
```
### sfc-to-tsx.js
Add type annotaions to stateless function components based on exsiting propTypes defination, turn from
```jsx
...
const Counter = ({ unit, count, lowerLimit, onCountChange}) => {
return (
-
{count}
{unit}
+
);
};
Counter.propTypes = {
active: PropTypes.bool,
name: PropTypes.string,
count: PropTypes.number,
unit: PropTypes.node,
lowerLimit: PropTypes.number,
upperLimit: PropTypes.number,
onCountChange: PropTypes.func,
};
...
```
to:
```jsx
...
const Counter: React.SFC = ({ unit, count, lowerLimit, onCountChange}) => {
return (
-
{count}
{unit}
+
);
};
interface CounterProps extends BaseProps {
active?: boolean,
name?: string,
count?: number,
unit?: any,
lowerLimit?: number,
upperLimit?: number,
onCountChange?: any,
}
...
```
## Debug
> VS Code debug tool + nodejs debugger is heavilly recommended;
> sample config: .vscode/launch.json
```json
{
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Launch via NPM",
"runtimeExecutable": "npm",
"runtimeArgs": ["run", "dev"],
"port": 9229
}
]
}
```
