@luly/cli v2.0.0

Luly: Basic Backend Development Framework with Hexagonal Architecture based on Express

Global Installation

npm install -g @luly/cli

Create a new project

luly new project_name

Add a new module

luly create module module_name

This command creates a module structure:

module-name
    |----Application
    |     |----module-name.service.ts
    |     |----Controller
    |           |----module-name.controller.ts
    |----Domain
    |     |----Interfaces
    |            |----module-name.interface.ts
    |----Infrastructure
        |----module-name.repository.ts

Controllers

Controllers for each module are created when generating the module. To use these controllers, you need to register them in the router.ts of the project, located at project-name/src/router.ts.

//router.ts
const controllers = [UserController];
const appRouter = setRoutes(controllers, express.Router());

These controllers use decorators to define routes and middlewares.

Router

Use @Router('path') to specify a general route for the controller. Use it before the class. Example:

@Router("user")
export class UserController {
}

Methods

You can use the following decorators to define method routes:

• @Post('path')
• @Get('path')
• @Put('path')
• @Delete('path')

The path in decorators follows Express logic, so you can pass parameters in the same way, like @Get('user/:id').

When using decorators, methods inherit req, res, and next from Express.

Example:

@Post('user')
createUser(req, res, next) {
    const { name, last_name } = req.body;
    res.send({
        message: "User created successfully"
    });
}

Middleware

The @Middleware([]) decorator takes an array of middlewares as a parameter. These middlewares run before each method in the order they are listed. This decorator should be placed after the method's decorator and before the method itself. Also it works after @Router('')

Example:

@Get('user')
@Middleware([authMiddleware, secondMiddleware])
getUser(req, res, next) {
}

Middleware example:

//authMiddleware.ts
function authMiddleware(req, res, next) {
    //your code here
    next();
}
export default authMiddleware;

Build

To compile the project, use the following command:

luly build

Compiled files are generated by default in /dist. You can configure tsconfig.json to change the output dir.

You can do a node dist/index.js to execute the compiled proyect.

CLI

The luly.config.json file is only necessary to specify the main project path to Luly. The contents of luly.config.json are not used in the framework; this file is only used for verification of being in the main path of a Luly project. In the future, it may be used to add necessary information.
