Deploy an Express API to Vercel

I get asked how to do this a lot so I thought I'd make a video about it.
Serverless functions on vercel are typically stand alone request handlers, but it is possible to deploy an entire Express API as a single serverless function. In this video I show how to do that.

    HI! how would you connect to mongo db database from the main file instead of from each model? Before this change, I was connecting from the index on src, having one single connection, but now I had to move that to each model since if I try to connect from the index file it never connects thanks!

    I think you forgot the most important thing, the API should be consumed by a client. I'd love to see the cors setup since Vercel has a specific setup. The API is only for devs so any person without dev skills won't ever use that!

    Isn't this an anti-pattern (lamba monolith)? Our entire application is running in a single serverless function, meaning everything which is imported is imported, parsed, and interpreted on every request. Unless Vercel does some magic behind the scenes?

  • @CodingGarden

    @CodingGarden

    Жыл бұрын

    Serverless functions have a "cold start" for the first request but are then "warm" for subsequent requests, and stay running for a certain amount of time. So yes the cold start time is potentially slower for an entire express app vs a single request handler. vercel.com/guides/how-can-i-improve-serverless-function-lambda-cold-start-performance-on-vercel

    Any service that allows you to deploy long lived containers would work. fly.io render.com and railway.app seem to have the most vercel like experience. I have several AWS Lightsail instances that I use for my websocket services. Any VPS would work.

    @CodingGarden thanks I'll take a look . Either way my server is a lot better in the sense I matched your setup and now it all is split up whereas I had EVERYTHING in the index file no app file no api folder it was meant to be a simple show data backend api point I added in some crud operations so the file was getting quite long but now I have more of a product I can use for multiple front end projects. Once I do hammer out this last bit I will have a solid end point to use for all front only projects in my portfolio which I feel should nicely round out a front end dev portfolio. So that's a huge use case for those wondering.
