Description:

sevr

A library for building REST APIs easily with Dart modeled after Express JS for Node Js.
The library is still a work in progress and open to contribution.
Created with StageHand - license.
Inspiration #
Our inspiration is the simplicity of express js 👏.
Installing #
Add the following to your pubspec.yaml file:
dependencies:

Usage #
A simple usage example:
import 'dart:io';

import 'package:sevr/sevr.dart';
import 'package:path/path.dart' as p;

main() {
var serv = Sevr();

//let sevr know to serve from the /web directory
serv.use(Sevr.static('example/web'));

//Use path to get directory of the files to serve on that route
serv.get('/serve', [
(ServRequest req, ServResponse res) {
return res.status(200).sendFile(p.absolute('example/web/index.html'));
}
]);

//get request
serv.get('/test', [
(ServRequest req, ServResponse res) {
return res.status(200).json({'status': 'ok'});
}
]);

//post request
serv.post('/post', [
(ServRequest req, ServResponse res) async {
return res.status(200).json(req.body);
}
]);

// request parameters
serv.get('/param/:username', [
(ServRequest req, ServResponse res) {
return res.status(200).json({'params': req.params});
}
]);

// query parameters
serv.get('/query', [
(ServRequest req, ServResponse res) {
return res.status(200).json(req.query);
}
]);

//Upload Files
serv.get('/upload', [
(req, res) async {
for (var i = 0; i < req.files.keys.length; i++) {
//Handle your file stream as you see fit, write to file, pipe to a cdn etc --->
var file = File(req.files[req.files.keys.toList()[i]].filename);
await for (var data
in req.files[req.files.keys.toList()[i]].streamController.stream) {
if (data is String) {
await file.writeAsString(data, mode: FileMode.append);
} else {
await file.writeAsBytes(data, mode: FileMode.append);
}
}
}

return res.status(200).json(req.body);
}
]);

//Bind server to port 4000
serv.listen(4000, callback: () {
print('Listening on port: ${4000}');
});
}

Create Server Connection
Pass in the port of your choice in this case: 4000
serv.listen(4000, callback: () {
print('Listening on port: ${4000}');
});

Make Server Requests

Create requests by passing in the desired route.
Put route Controllers in a List of Functions (ServRequest is a helper class that binds to HttpRequest, while ServResponse binds to the response from the HttpRequest Stream).
Set response status res.status().

Other available request types:

PUT
PATCH
DELETE
COPY
HEAD
OPTIONS
LINK
UNLINK
PURGE
LOCK
UNLOCK
PROFIND
VIEW

serv.get('/test', [
(ServRequest req, ServResponse res) {
return res.status(200).json({'status': 'ok'});
}
]);

serv.post('/post', [
(ServRequest req, ServResponse res) async {
return res.status(200).json(req.body);
}
]);

Serve Files From Your Server

First Let Sevr know where you want to serve the files from with use() .
Here we used the .absolute() function from the path package, pass in the directory of your main file, in this case index.html.

//let sevr know to serve from the /web directory
serv.use(Sevr.static('example/web'));

//Use path to get directory of the files to serve on that route
serv.get('/serve', [
(ServRequest req, ServResponse res) {
return res.status(200).sendFile(p.absolute('example/web/index.html'));
}
]);
