Getting Started

To integrate @knovator/masters-node, you should be having basic nodejs application up and running with express (optionally using mongoose for mongodb database). @knovator/masters-node add routes for masters in application.

Prerequisites

It's good start to have nodejs application up and running with express (optionally using mongoose for mongodb database). Good to have used i18next to add message in response codes.
routes uses mongoose connection established by application, so it's required to connect to database before using package. Example,
```
// db.js
const mongoose = require('mongoose');

mongoose
  .connect('mongodb://localhost:27017/knovator')
  .then(() => console.info('Database connected'))
  .catch((err) => {
    console.error('DB Error', err);
  });

module.exports = mongoose;
```

Image upload route for upload & remove is needed to declare externally. Example,

// fileRoute.js
const express = require('express');
const router = express.Router();

router.post(`/files/upload`, (req, res) => {
    // TO DO: some file storage operation
    let uri = "/image.jpg";
    let id = "62c54b15524b6b59d2313c02";
    res.json({
      code: 'SUCCESS',
      data: { id, uri },
      message: 'File uploaded successfully'
    });
});

router.delete(`/files/remove/:id`, (req, res) => {
    // TO DO: some file remove operation
    res.json({
        code: 'SUCCESS',
        data: {},
        message: 'File removed successfully'
    })
})

module.exports = router;

Sample App file

  require('./src/db');
  require('./src/models/file');

  const cors = require('cors');
  const express = require("express");
  const fileRoutes = require('./fileRoute.js');
  const PORT = 8080;

  const app = express();
  app.use(cors());
  app.use(express.static("public"));
  app.use(fileRoutes);

  // ...
  app.listen(PORT, () => {
      console.log(`App started on ${PORT}`);
  });

Installation

Install library

npm install @knovator/masters-node
# or
yarn add @knovator/masters-node

Usage

App/Main file is a good place to use @knovator/masters-node

  ...
  const { masters } = require('masters-node');
  
  // ...
  app.use("/admin/masters", masters());
  app.listen(PORT, () => {
      console.log(`App started on ${PORT}`);
  });

Masters package allows providing authentication, logger and catchAsync functions as parameters.

app.use("/admin/masters", masters({
  authentication: (req, res, next) => {...},
  logger: console,
  catchAsync: (function) => (req, res, next) => {...}
}));

parameter explanations

authentication
- Provides ability to add authentication to routes
```
// default
(_req, _res, next) => {
  return next();
}
```
logger
- Provides ability to add logging for Database and Validation
```
// default
console
```

catchAsync

Wraps functions to handle async errors

// default
function catchAsync(fn) {
  return function (req, res, next) {
    Promise.resolve(fn(req, res, next)).catch((err) => {
      // this.logger.error(err.message);
      res.status(internalServerError).json({
        code: RESPONSE_CODE.ERROR,
        message: err.message,
        data: {},
      });
    });
  };
}

Routes Infomration

Response follows following structure

{
  code: RESPONSE_CODES,
  message: "" // if internationalized is applied
  data: {}
}

Response Codes

Code	Description
SUCCESS	When request fullfiled without error
ERROR	When request fullfiled with error

Custom Validation messages

Message	Description
Master exists	When master/submaster with same code is exist in database

HTTP Status Codes

HTTP	Description
200	When request fullfiled without error
201	When document is created
500	When internal server occurred
422	When Validation error occurred

Routes

Route	Description
`/create`	Creates Master/SubMaster record
`/update:id`	Updates Master/SubMaster record
`/partial-update/activate/:id`	Turn on/off `isActive` field based on body data
`/partial-update/default/:id`	Turn on/off `isDefault` field based on body data
`/partial-update/web-visible/:id`	Turn on/off `isWebVisible` field based on body data
`/partial-update/sequence/:id`	Sets sequence of record with `:id`, and updates affected records sequence
`/delete`	Delete the record whose `id` send in body

`i18n` code for messages

Nextjs i18n package adds facility for internationalization in nodejs application, and it's used in following mannerr

// usage
req?.i18n?.(CODE)

CODE	Description
`(master/submaster).create`	When record is created
`(master/submaster).update`	When record is updated
`(master/submaster).activate`	When `isActive` is set to true
`(master/submaster).deactivate`	When `isActive` is set to false
`(master/submaster).display`	When `isWebVisible` is set to true
`(master/submaster).notDisplay`	When `isWebVisible` is set to false
`(master/submaster).default`	When `isDefault` is set to true
`(master/submaster).notDefault`	When `isDefault` is set to false
`submaster.seq`	When sequence is updated
`(master/submaster).delete`	When delete is performed
`(master/submaster).findAll`	When all data is fetched
`(master/submaster).notFound`	When Master/Submaster data is not found

`descriptor` codes

Code	Description
`master.create`	For Create API
`master.update`	For Update API
`master.active`	For `isActive` toggle API
`master.default`	For `isDefault` toggle API
`master.webVisible`	For `isWebVisible` toggle API
`master.sequence`	For `sequence` update API
`master.softDelete`	For Soft-Delete API
`master.list`	For List API

You can prefix descriptors by adding MASTERS_DESCRIPTOR_PREFIX in environment variables.
