NAPIM

Node API Maker built with polka and nodejs

Overview

The idea is to make API development quick and easy. Every single end point is handled by one file that called service. One service include:

• Input validation
• DB transaction (optional)
• Input mapping
• Error handling

Installation

1. Install Napim CLI globally (optional)

   npm install -g napim-cli

   you can check by running napim --version

2. Generate Napim template (optional)

   napim init project-name

   change project name with your actual project name

   for typescript support, ad -ts in the end eg:napim init project-name -ts

3. Install dependency

   cd project-name && npm install

4. Update Napim to current version npm install napim

File and Folder Structure

This is default folder structur for typescript mode:

1.
2|-- dist //compiled script will be here
3|-- log //all error log will be here
4|-- src
5    |-- middleware
6    |-- model
7    |-- service
8|-- stub //napim template generator, edit the template to match your needs
9    |-- middleware.napim
10    |-- model.napim
11    |-- service.napim
12    index.ts //your main js file
13|-- .env
14|-- .gitignore
15|-- knexfile.js // by defaut napim use knex for Database Query Builder, delete it if you use nosql like mongo
16|-- package.json
17|-- router.json //this file will map your API endpoint to execute service file
18|-- tsconfig.json

Generate NAPIM File

• Generate Service

  napim make:service service-name

  by default service have method GET, you can change by append the method argument in the end, eg:

  napim make:service login --post

  this command will create file login_post.ts in service folder and append route data to router.json with tag: "default" inside post array, just check it :)

  By default, prefix for default tag is api, so you can execute the service by access endpoint POST:[host]/api/login

  If you want to add some tag, for example secure (You can add middleware like Auth later), add tag argument

  napim make:service users --tag=secure

  You can also make dynamic endpoint, for example find user by some id

  napim make:service users/:id

2. Generate Model

   If you use Model like Objection.js to you can generate Objection model by

   napim make:model ModelName

   if you prefer to use raw query, just import {db} from "napim" and use it like db.query(trx)... see knex documentation for detail

   If you want to use db transaction, just change transaction to true in your service file, ez

   You like NoSQL like mongo, just edit your .env add DB_DRIVER=mongo and create your own Model or Schema and import to your service like usually

   TODO: implement db transaction for mongo

3. Generate Middleware

   Want to make Auth, JWT, or handle uploaded file (eg: using multer) you can create it in middleware

   napim make:middleware JWT

   then use it in router, append it in middleware array for example:

   1//router.json
   2[
   3    {
   4        "tag": "default",
   5        "prefix": "/api",
   6        "middleware": [],
   7        "get": [],
   8        "post": [
   9            {
   10                "path": "/login",
   11                "service": "/login_post"
   12            }
   13        ]
   14    },
   15    {
   16        "tag": "secure",
   17        "prefix": "/api/secure",
   18        "middleware": [
   19            "JWT"
   20        ],
   21        "get": [
   22            {
   23                "path": "/products/:id",
   24                "service": "/products/_id_get"
   25            }
   26        ]
   27    },
   28    {
   29        "tag": "admin",
   30        "prefix": "/api/admin",
   31        "middleware": [
   32            "JWT",
   33            "Admin"
   34        ],
   35        "get": [
   36            {
   37                "path": "/products",
   38                "service": "/products_get"
   39            }
   40        ],
   41        "post": [
   42            {
   43                "path": "/products",
   44                "service": "/products_post"
   45            }
   46        ],
   47        "delete": [
   48            {
   49                "path": "/products/:id",
   50                "service": "/producst/_id_delete"
   51            }
   52        ],
   53        "patch": [
   54            {
   55                "path": "/products/:id",
   56                "service": "/producst/_id_patch"
   57            }
   58        ]
   59    }
   60]
