A simple CLI utility for quickly creating Express-based servers with a single configuration file
npm install fastapi---
Fastapi is a simple command-line utility that allows you to create an Express-based server based off of a single configuration file. It's useful for quickly spinning up mock APIs, among other things.
Install the fastapi command-line utility via npm i -g fastapi. Next, create a configuration file like the one we see here.
`` javascript`
// config.js
module.exports = {
// A unique ID for this API
'id': 'my-api',
// The port on which Express is to listen
'port': 7050,
// Whether or not to log incoming requests to the console (default: true)
'log': true,
'routes': {
'/api/v1/ping': {
'get': (req, res, next) => {
return res.send('pong');
}
}
}
};
Next, launch your server as shown below.
`
$ fastapi -c ./config.js
A configuration file can define multiple APIs by exporting an array of configuration objects, like we see here.
`
module.exports = [
{
'id': 'api1',
'port': 7050,
'log': true,
'routes': {
'/api/v1/ping': {
'get': (req, res, next) => {
return res.send('pong');
}
}
}
},
{
'id': 'api2',
'port': 7051,
'log': true,
'routes': {
'/api/v1/foo': {
'get': (req, res, next) => {
return res.send('bar');
}
}
}
}
];
