Now let’s create a FastAPI sample very fast
python -m venv .venv
source .venv/bin/activate
pip install fastapip uvicorn
vim main.py
## Add the following content to `main.py`
from fastapi import FastAPI
app = FastAPI()
@app.get("/")
async def root():
return {"message": "Hello World"}
uvicorn main:app --reloadNodeJS Express Create Project
If you haven’t installed NodeJS on your local, you need to install it before creating an express project: https://leftsidemonitor.com/linux-install-nodejs-and-npm-using-terminal/
mkdir myexpress cd myexpress npx express-generator npm install DEBUG=myexpress:* npm start
By default the web project is running at the following location: http://localhost:3000/
Let’s test by adding a greeting route.
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
router.get('/hello', function(req, res, next) {
greeting = 'Hello ' + req.query.name;
console.log(greeting);
res.render('index', { title: greeting});
})
module.exports = router;Restart server for testing:
DEBUG=myexpress:* npm start
