NodArt - The Art of Node.js.

A complete web framework
for creating microservices and
large-scale server-side applications for businesses

---

The framework adheres to the concept of "just install and use". Everything you need to run a server application:

1. MVC; OOP (TypeScript, ECMAScript 6)
2. ORM client, Working with databases (MySQL, PostgresSQL, SQLite, MSSQL, OracleDB, CockroachDB, Amazon Redshift)
3. Working with a session
4. Templating
5. Error and Exception handling
6. Working with a command line; Creation of custom commands
7. Routing
8. Custom events and states
9. Dependency injection
10. Observer pattern
11. Repository pattern

Everything of this is provided out of the hood. All that is needed for some of the above things to work is to specify the basic settings in the configuration file.

The framework provides a very flexible architecture, making it easy to extend and customize all of these things, up to and including completely changing the basic behavior by specifying class loaders and references in the same configuration file.

The framework is independent, thus it doesn't rely on other frameworks like Express.

APPLICATION CREATION, INITIALISATION AND START

1. GIT

it downloads the current framework version's application with full usage examples.

git clone https://github.com/nodart-labs/nodart-app.git

2. CLI

it creates a base application structure with some usage examples.

npx nodart create-app

it creates a microservice application file. Use flag "--js" when you are not using typescript in project.

npx nodart microapp --js[optional]

---

3. INITIALISATION AND START

You can launch microservice or monolithic apps, or you can combine them, depending on the requirements. In this article, you can read more about application architecture.

BASIC INITIALISATION:

import {App} from "nodart"

const config = require('./config')

// Be aware that this fundamental initialization 
// automatically creates the necessary app files and folders.
// (database folder, controllers folder, models folder, 
// services folder, views folder and etc.)

new App({...config}).init().then(app => {

    const server = app.serve(3000, 'http', '127.0.0.1')
    
    // do anything on startup, for example:

    // configure server:
    server.timeout = 30000 // setting max timeout on requests

    // or create payload for all HTTP requests:
    app.setHttpRequestPayload((req, res) => {})
    
    // or launch HTTP service: 
    const http = app.service.http()
    
    http.get('url/path/with/:params', (scope) => {})
    
})

---

STARTING HTTP SERVICE:

import {App} from "nodart"

const config = require('./config')

const {app, http, server} = new App({...config}).start(3000)

// base HTTP processing:

http.get('/path/:first/:second/:+optional_id?', ({route, respond, http}) => {
    
    const {first, second, optional_id} = route.params
    
    const {queryParam} = route.query

    // sending template from views folder:
    respond.send.view('path/to/template', {queryParam})

    // sending file:
    http.sendFile('path/to/file.png', 'image/png')
    
    // sending response JSON:
    respond.send.data({first, second, optional_id}, 200)
    // or just:
    return {first, second, optional_id}

})

// fetching data from POST request:

http.post('/', ({http}) => {

    const {someData} = http.data

})

// fetching data from POST miltipart/form-data:

http.post('/', async ({http}) => {

    const {fields, files} = await http.form.fetchFormData()
    
    const stat = http.form.stat('field_name')

})

// dealing with services and models:

import {SampleService} from "./services/sample"
import {SampleModel} from "./models/sample"

http.get('/', async ({service, model}) => {

    const sampleService = service.sample as SampleService
    const sampleModel = model.sample as SampleModel

    const users = await sampleModel.query.select().table('users')

    sampleService.scope.http.send({users})

})
