|
> Patch console methods to intercept output
|
|
|
|
## Install
|
|
|
|
```
|
|
$ npm install patch-console
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
import patchConsole from 'patch-console';
|
|
|
|
const restore = patchConsole((stream, data) => {
|
|
// stream = 'stdout'
|
|
// data = "Hello World"
|
|
});
|
|
|
|
console.log('Hello World');
|
|
|
|
// Restore original methods
|
|
restore();
|
|
```
|
|
|
|
## API
|
|
|
|
### patchConsole(callback)
|
|
|
|
After this function is called, output from console methods will be intercepted and won't show up in the actual stdout or stderr stream.
|
|
To restore original console methods and stop intercepting output, call the function which `patchConsole()` returns.
|
|
|
|
#### callback
|
|
|
|
Type: `Function`
|
|
|
|
Function that will be called when output from one of the console methods is intercepted.
|
|
First argument is name of the stream (`"stdout"` or `"stderr"`), second argument is output itself.
|
|
|
|
