Práctica 4 -- Microsoft Launch X

Contribución Open Source

1. Hacer un Fork del repositorio de Carlo fizzbuzz.
2. Clonar el repositorio en maquina personal.
3. Es de buenas prácitcas Crear una Rama nueva al hacer contribuciones.
4. Realizar cambios de configuración
   4.1 Agregamos dependencias eslint con el comando npm install eslint --save -dev
   4.1.1 Modificamos el archivo package.json:
   Agregando correctamente la ruta para "test"
   4.1.2 Configurar eslint con el comando npm init @eslint/config
   4.1.3 Agregar reglas que se ocuparan en el proyecto dentro del archivo ".eslint.js":
5. Agregar nuevo requerimiento
   5.1 Agregamos las pruebas necesarias y las hacemos fallar:

• Prueba de filtrado por Stack

test("Requerimiento 4: Filter explorers by Stack", () => {
        const explorers=Reader.readJsonFile("explorers.json");
        const explorersInStackE = ExplorerService.getExplorersByStack(explorers,"elixir");
        const explorersAmountInStackE = explorersInStackE.length;
        expect(explorersAmountInStackE).toBe(9);
    });

• Prueba para el controlador

test("1) Regresar lista de explorers por Stack", () =>{
        const ListExplorersByStack = ExplorerService.getExplorersByStack(explorers,"reasonML");
        expect(ListExplorersByStack.length).toBeDefined();
    });

5.2 Agregamos el código funcional para hacer pasar nuestras pruebas

• Método estático para filtrar por Stack agregado al archivo ExplorerService.js

static getExplorersByStack(explorers,stack){
           const explorersInStack = explorers.filter((explorer) => explorer.stacks.includes(stack));
           return explorersInStack;
    }

• Método estático para hacer pasar la prueba del controlador agregado al archivo ExplorerController.js

static getExplorersByStack(stack){
        const explorers = Reader.readJsonFile("explorers.json");
        const getListExplorersByStack = ExplorerService.getExplorersByStack(explorers,stack);
        return getListExplorersByStack;
    }

6. Agregamos el Endpoint en el archivo server.js

• Ejemplo: localhost:3000/v1/explorers/stack/:elixir

app.get("/v1/explorers/stack/:stack", (request, response) => {
    const stack = request.params.stack;
    const explorerListByStack = ExplorerController.getExplorersByStack(stack);
    response.json(explorerListByStack);
});

7. Levantamos el servidor y probamos en el browser localhost:3000/v1/explorers/stack/:elm

Endpoint	Request	Response
localhost:3000/v1/explorers/stack/:stack	localhost:3000/v1/explorers/stack/elm	[{"name":"Woopa3","githubUsername":"ajolonauta3","score":3,"mission":"node","stacks":["elixir","groovy","reasonML"]},{"name":"Woopa5","githubUsername":"ajolonauta5","score":5,"mission":"node","stacks":["javascript","elixir","elm"]},{"name":"Woopa9","githubUsername":"ajolonauta9","score":9,"mission":"java","stacks":["javascript","elixir","groovy","reasonML","elm"]},{"name":"Woopa10","githubUsername":"ajolonauta10","score":10,"mission":"java","stacks":["javascript","elixir","groovy","reasonML","elm"]},{"name":"Woopa11","githubUsername":"ajolonauta11","score":11,"mission":"node","stacks":["javascript","elixir","groovy","reasonML","elm"]},{"name":"Woopa12","githubUsername":"ajolonauta12","score":12,"mission":"node","stacks":["javascript","elixir","groovy","reasonML","elm"]},{"name":"Woopa13","githubUsername":"ajolonauta13","score":13,"mission":"node","stacks":["javascript","elixir","groovy","reasonML","elm"]},{"name":"Woopa14","githubUsername":"ajolonauta14","score":14,"mission":"node","stacks":["javascript","elixir","groovy","reasonML","elm"]},{"name":"Woopa15","githubUsername":"ajolonauta15","score":15,"mission":"node","stacks":["javascript","elixir","groovy","reasonML","elm"]}]
