Customizable HTTP Errors, compatible with es6 "throw" syntax, including a custom error handler for express APIs.
This package is not being maintained and may have errors.
npm i express-http-custom-error
Throwing an error:
const { BadRequest } = require('express-http-custom-error');
router.post('/signin', async (req, res, next) => {
try {
const { username } = req.body;
if (!username) throw new BadRequest('Must include username.');
...
} catch (err) {
next(err);
}
});
Using the error handler:
const { errorHandler } = require('express-http-custom-error');
const app = express();
...
// All routers and other middleware must go before the error handler.
app.use(errorHandler);
