error-express-handler

This package exports a middleware for express that handles Error and HttpError(custom package type).

Install​

npm install --save @map-colonies/error-express-handler

API documentation​

Check the autogenerated documentation here.

Usage​

Add the handler as the last middleware, so any error forwarded by the controllers will be handled. If the value of NODE_ENV is production the error message will be redacted and a generic one will be sent instead. In development, in addition to the error message, the stack trace of the error will be included in the response.

import express from 'express';
import { getErrorHandlerMiddleware } from '@map-colonies/error-express-handler';

process.env.NODE_ENV = 'development';

const app = express();

app.use('/meow', fn);

app.use(getErrorHandlerMiddleware());

app.listen(8080, function () {
  console.log('server is up');
});
