About The Project

Get your backend up in 5 seconds! Dartion aims to make it easier for those who take front-end video lessons in languages like Flutter and need a server to implement and test their codes. Just get the DartSDK, install Dartion, initialize the server and start it, that's all! It comes with support to HTTP requests and JWT Authentication.
After installing, just populate the db.json file and you will have a simple and ready to use database.

How to Use



Updates Dartion's version:

dartion upgrade

Init server:

Execute the command below in an empty folder, it will create the base configuration files for your server:

dartion init

Start server:

The command below will boot the server based on the settings configured in the config.yaml you have now on your created folder.

dartion serve

If you want to change those settings, you can edit the config.yaml as you like. Refer to the documentation on the init and serve commands, and also the Database class, to know a little bit more about these configurations.

Route system

When running Dartion we have a structure based on RESTful, while the data persists in a JSON file in the folder, named by default db.json.

GET    /products     -> Get all products
GET    /products/1   -> Get one product
POST   /products     -> Add more one product
PUT    /products/1   -> Edit one product
PATCH  /products/1   -> Edit one product
DELETE /products/1   -> Delete one product

POST, PUT and PATH requests must have their body as JSON. It is not necessary to pass the ID, it is incremented automatically.

File Upload

You can configure Dartion to accept upload files such as images, pdf's, etc... Adds storage properties to config.yaml

  name: "file"
  folder: storage/

File uploads work with "Multipart-form", so you can use the name property to name your upload. We can choose which folder the uploaded files will be on the server using the folder property. Then you will have two reserved routes, one to upload files and the other to retrieve those binaries.

POST /storage               -> Send files in Multipart-form
GET  /file/:your-file.ext   -> Retrieve file 

NOTE: The /storage route returns the file name.


You can use JWT Authentication in two steps.

  1. Use the auth property in your config.yaml
name: Test
port: 3031
db: db.json
statics: public

  key: dajdi3cdj8jw40jv89cj4uybfg9wh9vcnvb
  exp: 3600
    - animals
    - cities

That's enough to protect your routes. The auth property takes some configuration parameters:

key -> To sign your token
exp -> Token expiration time in seconds
escape -> List of routes that will not be affected by token protection
  1. Login using the /auth route:

To retrieve the token you need a credential. A credential is basically base64(email:password)

See an example in Dart:

String email = "jose@gmail.com";
String password = "123";
String info = "$email:$password";
String encode = base64Encode(info.codeUnits);

String credencials = "Basic $encode";

You can now make a GET request to /auth, passing the credentials in the authorization header.

exemple in dart

// Using the package http

Response response = await http.get(
  headers: {'authorization': credencials},

This will return the token and some user information.

  "user": {
    "name": "Jose",
    "email": "jose@gmail.com"
  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1ODc5NjQ1MTAsImlhdCI6MTU4Nzk2MDkxMCwiaXNzIjoiZGFydGlvIiwic3ViIjoibnVsbCJ9.5AeEIpYeu04fKINg6e8Ic5fpT0-KyZH8yPLOO6HoLVA",
  "exp": 3600

That's it! Now, just use the token to access the routes:

Response response = await http.get(
  headers: {'authorization': "Bearer $token"},


When using Authentication, you will need to have a users property in your db.json with a user list containing at least email and password in order to access.


The db.json on the root folder of this package was generated by running the tests contained on the test folder.
