It runs as a native compiled rust library within your Node.js project. Its aim is to make it easy to switch from using ExpressJS to Warp (Rust) while keeping a Node.js runtime and using a similar syntax
You can open GET endpoints that include request query strings and headers. Paths must be absolute (no slashes yet). The endpoints can reply with any type of data (text,html,json, or any buffer) and can also set its own custom response headers
No POST/other functionality is available, but it can be developed. Feel free to fork/PR
You will need to compile using the same target environment. For example, if you plan on using this on Google App Engine's Node.js Standard Environment, you will need to compile from a 2020 Linux distro to match GAE's glib.c runtime. The compiled binary included in this release is exactly that
To compile, simply run
npm install
cargo build
npm run buildThis will produce the warp_like_express.node file that you can then import into your Node.js project
The file warp_like_express_test.js is included to test opening a Rust server from this project. To run, simply run
node warp_like_express_test.jsThis will start a rust-warp server listening on port 8081 with the following endpoints:
GET /test_text
GET /test_json
GET /test_data
GET /test_imageEach endpoint is served by a rust-warp server that then calls your JS backend to execute your custom JS logic
To use in your project, you need to copy both the warp_like_express.node and warp_like_express.js into your Node directory
The following code opens the above 4 endpoints, and includes ExpressJS's equivalent in comments
var warp_like_express = require("./warp_like_express.js");
// equivalent to using below
// const express = require('express');
warp_like_express.get("test_text",(req, res)=>{
console.log("test_text called with query strings: "+JSON.stringify(req.query));
console.log("test_text called with user-agent header: "+req.header("user-agent"));
res.header("some", "response_header");
res.send("hi from js");
});
