.

Install NodeJS and ExpressJS

https://gist.github.com/c6f950dc2f093f80eb33a011ebe35164

Create Folder structure.

Create too the README.md, LICENCE & .gitignore.

.

Set Express.

In main file. e.g.: app.js

Definition of MVC entities.

In this example, 3 entities will be used.

• Subscriptions.
• Promotions.
• Users.

MVC: Create Routes.

Express documentation: https://expressjs.com/es/guide/routing.html

In main file. e.g.: app.js

https://gist.github.com/41b43826c2b4ca44f65507d1d0fe0c1e

Test some routes:

· http://localhost:5000/ · http://localhost:5000/subscriptions · http://localhost:5000/users · http://localhost:5000/sdfg

MVC: Modularize and create routes files (entities).

A ROUTER is an "entity". BREAD: Browse, Read, Edit, Add, Delete. If preparing the backend to consume as API with the frontend, static is not defined as entity.

.

In main file. e.g.: app.js

https://gist.github.com/cdbac3179be1d2cdc5d30f1a6e8ee1f9

In the router file. e.g.:subscriptionsRouter.js

Idem in the other routers entities. e.i.: staticRouter.js, promotionsRouter.js, usersRouter.js.

https://gist.github.com/bfdf856eecef09f93ce36a8de953ce76

MVC: BREAD entities.

7 paths if views are rendered. 5 routes if we prepare the backend to consume it via API: 1 BROWSE - See all 3 EDIT - Edit one (edit form) (only for views) 4 EDIT - Edit one 5 ADD - Add one (creation form) (only for views) 6 ADD - Add one 7 DELETE - Delete one 2 READ - See one

In the router file. e.g.:subscriptionsRouter.js

Idem in the other routers entities. e.i.: staticRouter.js, promotionsRouter.js, usersRouter.js.

MVC: Create controllers files.

MVC: Tell routes the controller method.

In the router file. e.g.:subscriptionsRouter.js

Idem in the other routers entities. e.i.: staticRouter.js, promotionsRouter.js, usersRouter.js.

https://gist.github.com/006a5eae261f9a353c053e833a146e61

MVC: Create the controller standard methods.

In the router file. e.g.:subscriptionsControllers.js

Idem in the other routers entities. e.i.: staticRouter.js, promotionsRouter.js, usersRouter.js,

In this part of the process the control methods should show the results. The database is in charge of displaying the results.

• [Edit the methods of the controller from the database.md](./Edit the methods of the controller from the database.md).

• [Edit the methods of the controller using JSON files.md](./Edit the methods of the controller usin JSON files.md).

Another option is to send the views directly instead of the API, in this case with EJS as template engine.

• [MVC: Tell the controller to show the views](./MVC Tell the controller to show the views.md).

Install thrid-party dependencies.

.

• dotenv.md.

  Configuration in the environment separate from code.

• passport.md.

  If you need to manage the sessions, e.g. Superadmin.

• express-session.md.

  Create a session middleware.

• cookie-parser.md

  Parse Cookie header.

Rest API: Create a Json file in src for each entity with its data.

Rest API: Set the Json Objet.

In main file. e.g.: app.js

https://gist.github.com/e4380a90156b0578cd524f6c9549922d

Rest API: Set how Express handles information in forms.

In main file. e.g.: app.js

https://gist.github.com/bc986d387cae559a9fab450408fdb12e

Json Models lo utilizo porque como uso Json, saco los métodos más comunes afuera json Models I use it because as I use Json, I pull the most common methods outside

las rutas o controladores o sus métodos (no sé) ahora envian respuestas Json por que son APIs routes or controllers or their methods (I don't know) now send Json responses because they are APIs

<<<<<<< HEAD https://www.npmjs.com/package/cors

Extraigo las variables de desarrollo en archivos de producción .env y hago la documentación .env.example

requiero lainstalo la librería https://www.npmjs.com/package/dotenv

utilizo process.env para extraer las vaiables las pongo utilizo en app.js y ahora van a ser dínámicas

Si hago pública la API. ver el tema de los token en la API (ver ejemplo en promotionsController) (el método serch se define desde el controlador, añadirlo en el lugar que va en el readme.md) Tengo que ver cuantas request pueden hacer por usuario.
