Speedily-js NPM

speedily-js allows you to quickly create an express server with minimal code

Install

npm install speedily-js

Usage

Simple

import { Server, Controller } from 'speedily-js';

const server = new Server(3000);

const homeController = new Controller('/home').get('/', () => {
    return 'Home';
});

server.setControllers([homeController]);

server.run();

Using the parameters

getOrFail automatically throws a 400 error if the parameter could not be found

const productController = new Controller('/products')
    .get('/', (context: Context) =>
        productService.findAll([], context.queryParams.get('categoryId'))
    )
    .get('/:id', (context: Context) =>
        productService.findOne(context.params.getOrFail<number>('id'))
    );

Post data

You can use class-validator to check your dto.

class CreateProductDto {
    @IsString()
    @Length(4)
    name!: string;

    @IsString()
    @IsOptional()
    description!: string;

    @IsNumber()
    quantity!: number;

    @IsNumber()
    categoryId!: number;
}

const productController = new Controller('/products').post(
    '/',
    (context: Context) =>
        productService.create(context.body.get<CreateProductDto>()),
    { bodyValidator: CreateProductDto }
);

Throw an error

const productController = new Controller('/products').post(
    '/',
    (context: Context) => {
        throw new BadRequestError(`Why not`);
    }
);

You can also create your own errors

export class CustomError extends HttpError {
    constructor(message: string) {
        super(418, message);
    }
}
const productController = new Controller('/products').get(
    '/',
    (context: Context) => {
        throw new CustomError(`Why not`);
        // or
        throw new HttpError(418, 'Why not');
    }
);

Authenticate your controllers

function auth(jwt: string, context: Context): Promise<boolean> {
    try {
        verify(jwt, environnement.API_SECRET_JWT);
    } catch (err) {
        return false;
    }
    return true;
}

const productController = new Controller('/products')
  .enableBearerAuth(auth)
...

Authenticate a specific route

You can also pass data to your routes and access them with context.data

const productController = new Controller('/products').get(
    '/:id',
    (context: Context) =>
        productService.findOne(context.params.getOrFail<number>('id')),
    {
        bearerAuthFnt: auth,
        data: {
            roles: ['admin', 'manager'],
        },
    }
);
