I have an Express REST API server written in TypeScript.
At first, I started server like this –
const initServer = async() => { await connectDb(); await server.listen(secrets.port, secrets.hostname, () => { logger.info( `Running server at http://$ {secrets.hostname}:$ {secrets.port} in $ { secrets.env } env and API version is $ {secrets.apiVersion}` ); }); } initServer().catch(error => logger.error(`Init server went wrong with: $ {error}`)); Then I read a blog post suggesting to use .then().catch() –
async function initServer() { // Connect the database first await connectDb() .then(() => // then start the server server.listen(secrets.port, secrets.hostname, () => { logger.info( `Running server at http://$ {secrets.hostname}:$ {secrets.port} in $ { secrets.env } env and API version is $ {secrets.apiVersion}` ); }) ) .catch(err => { logger.error(`Initializing server went wrong with: $ {err}`); process.exit(1); }); } Then I read another blog post saying “catch the error first” –
async function initServer() { // Connect the database first await connectDb() // then start the server .then(() => server.listen(secrets.port, secrets.hostname)) .catch(err => { logger.error(`Initializing server went wrong with: $ {err}`); process.exit(1); }) // then announce the server info .finally(() => { logger.info( `Running server at http://$ {secrets.hostname}:$ {secrets.port} in $ { secrets.env } env and API version is $ {secrets.apiVersion}` ); }); } But I feel like I’m not doing it right. Please educate me what I’m doing wrong.
How should I start the server?
