Code styling is handled by eslint
We're using the AirBnb configuration extended for typescript. It will ensure coherence across the whole codebase, and make sure you're following general good practices
Use npm run lint to check coding style and automatically fix errors
The application comes with a custom logger made with winston.
It allows you to output nicely formated logs as simply as
logger.info('Server listening on 8000')Error logs are written into logs/error.log, and a mix of all logs level from info are written into logs/all.log
In production mode, logs are not written in stdout, only in files
This is essential as console.log is a blocking operation
It reduces the IO usage too
Additionally, all requests are automatically logged too, thanks to morgan
Express doesn't handle errors thrown in an async context.
It means that even with an error middleware, errors won't be catched if they are thrown from an async handler, and your app will crash
I know
It's insane
To avoid this problem, handlers need to be wrapped in express-async-handler
router.post('/signin', handler(async (req, res) => {
/* Errors can safely be thrown */
}));
