What is Nolang

Nolang is a new programming language and can be used as a nodejs framework. In Nolang, everything is defined with JSON syntax, and code functions similarly to data. Programmers only need to define the entities when create programs with Nolang.

Usage of Nolang

Nolang is well-suited for developing back-end services, RESTful APIs, microservices, and even front-end applications.

Website

The official website of Nolang is https://nolang.org that includes documents.

Syntax

Syntax of Nolang is JSON only. For to be more easy it is possible to write with JSON5.

Describing entities

In NoLang, Entities are defined with JSON Schema plus some specific keywords added by NoLang.

The schema of an entity in its simplest format can be like this:

{
	"$id": "entity-schema-id",
	"properties": {
		"FieldName1": {
			"type": "string"
		},
		"FieldName2": {
			"type": "number"
		}
	}
}

Manipulating data in entities

When we want to ask from a NoLang program to do something, we must use NoLang Scripts.

{
	"$$schema": "entity-schema-id",
	"$$header": {
		"action": "C"
	},
	"FieldName1": "Hello",
	"FieldName2": 25
}

NoLang Endpoints

NoLang Endpoints are the ways To connect and send a Script to a NoLang app. Several types of endpoints are supported for example http, socket, ipc, redis and very more.

Nolang Application

Structure of a Nolang application is very Straightforward.

Structure of a NoLang app

• In every NoLang app there are some entities.
• It must be defined the entities' schemas in config file or in separate files.
• If this app stores data of entities the storage configuration must be defined in any schema or config file.
• It is necessary to define one or more endpoints that this app listens to.
• If this app needs to connect to other NoLang apps it can be defined in microservice configuration.

Application config file

To create a NoLang application, we need to have NodeJS installed. then in a directory for application there is the config file. Config file must be in JSON or JSON5 format and can have any name, its default name is app.json or app.json5

{
	"name": "sample app",
	"schemas": [
		{
			"$id": "entity-schema-id",
			"properties": {
				"FieldName1": {
					"type": "string"
				},
				"FieldName2": {
					"type": "number"
				}
			}
		}
	],
	"endpoints": [
		{
			"type": "http",
			"port": 80,
			"routes": [
				{
					"path": "/",
					"type": "html",
					"method": "post"
				}
			]
		}
	]
}
