Starting with v1.5.0,
serverless-http supports API Gateway binary modes. Binary support will base64 decode the incoming request body - when API Gateway specifies that it is encoded - and will base64 encode a response body if the
Content-Encoding matches a known binary type/encoding. This means you can gzip your JSON or return a raw image, but it requires advanced configuration within API Gateway and is generally not fun to work with (consider yourself warned!)
Existing serverless-http APIs (i.e. those that return JSON as text) should not be affected. See advanced configuration documentation for details.
This module allows you to 'wrap' your API for serverless use. No HTTP server, no ports or sockets. Just your code in the same execution pipeline you are already familiar with.
Before using this module, you should already understand API Gateway and AWS Lambda. Specifically, you must be using Proxy Integration.
You can use
connect or any
req, res type middleware) instead of
koa - it's all the same:
const serverless = ;const koa = ;// construct your app as normalconst app = ;// register your middleware as normalapp;// this is it!moduleexportshandler = ;
Your code is still running in Lambda and API Gateway. This means you are still subject to the file size restrictions, for example. You also cannot rely on your server being 'up' in the sense that you can/should not use in-memory sessions, web sockets, etc.
Think of this as a familiar way of expressing your API, not trying to make Lambda do something it cannot.
