Installation

Currently, only the Deno version of Lesan's framework is ready and usable, Node and Bun versions will also be ready soon.

Pre request

• At least version 7 of MongoDB must be installed.
• The latest version of Deno must be installed.
• It is good to have NodeJS installed on your system.
• If you need to see database information, it is better to install MongoDB Compass.
• Using a suitable editor such as:
  • VS Code please install deno extension
  • Lesvim The configuration of this editor is a bit difficult.
  • Helix The configuration of this editor is simple and the performance is excellent. Please add .helix/languages.toml file to the root of project and insert this config for better support of Deno.

Importing

After completing the prerequisites, create a file named mod.ts. Now just use the latest version of Lesan along with MongoClient in this file.

import {
  lesan,
  MongoClient,
} from "https://deno.land/x/lesan@vx.x.x/mod.ts"; // Please replace `x.x.x` with the latest version in [releases](https://github.com/MiaadTeam/lesan/releases)

const coreApp = lesan();

const client = await new MongoClient("mongodb://127.0.0.1:27017/").connect();

const db = client.db("dbName"); // change dbName to the appropriate name for your project.

coreApp.odm.setDb(db);

coreApp.runServer({ port: 1366, typeGeneration: false, playground: true });

Please replace x.x.x in the import link with the latest version in releases

Now run this command in the terminal:

deno run -A mod.ts

You should see this messsage:

HTTP webserver running.
please send a post request to http://localhost:1366/lesan
you can visit playground on http://localhost:1366/playground

Listening on http://localhost:1366/

Now you can visit the playground at http://localhost:1366/playground.

Because no database model and no function have been written yet, we still cannot send a request to the server.
