# Beautiful error reporting for express
[](https://travis-ci.org/hmil/express-youch)
Beautiful, spec-compliant error reporting for express.
## What does this do?
This express middleware simplifies debugging errors in express applications by presenting errors in a developer-friendly way.
Features:
- Beautiful HTML error reports thanks to [youch](https://github.com/poppinss/youch)
- Respects the `Accept` HTTP header
- Hides sensitive information when running in production
- Compatible with other error middleware (custom error pages, custom error logging, ...)
## Usage
```
npm install express-youch
```
```js
const { errorReporter } = require('express-youch');
app.use(errorReporter());
```
## Configuration options
### links
Add custom links to the error report.
```ts
app.use(errorReporter({
links: [
({message}) =>{
const url = `https://stackoverflow.com/search?q=${encodeURIComponent(`[adonis.js] ${message}`)}`;
return `Search stackoverflow`;
}
]
}));
```
## Recepies
### How do I customize the error pages?
When running in production (_ie. when the `NODE_ENV` environment variable is set to `production`._), `express-youch` will delegate HTML errors to the next error reporting middleware. Here is a basic example:
```js
const { errorReporter } = require('express-youch');
// First, pass the errors to the error reporter
app.use(errorReporter());
// Then add some custom handling logic
app.use(function (error, req, res, next) {
if (!res.headersSent) {
// If we get to this point, that means express-youch decided to delegate response rendering to the
// next handler in the chain. You can safely assume the client wants an HTML response here.
res .status(error.statusCode)
.render('error-page', { error });
} else {
next(error);
}
});
```
The error object contains the properties `statusCode` and `message`, which you may use to create different error pages for different error types.
### How to better manage my errors
You should us a combination of an asynchronous express router such as [this one](https://www.npmjs.com/package/express-async-router) and the **async/await** syntax to make sure no errors leak outside of your control.
