Loopback Component Traceability

Module for Loopback Framework that allows to keep a persisted traceability of custom operations over models

Installation

npm i -S github:aliatech/loopback-component-traceability.git#develop

Enable and configure component in component-config.json

"loopback-component-traceability": {
  "userModel": "User" // Model to use as events' author 
}

Enable model files in model-config.json:

"models": [
  ...,
  "../node_modules/@aliatech7loopback-component-traceability/models"
]

Enable mixin files in model-config.json:

"mixins": [
  ...,
  "../node_modules/@aliatech/loopback-component-traceability/mixins"
]

Configure models in model-config.json:

...
"ModelEvent": {
  "dataSource": "db",
  "public": false
},
...

Example: Change collection name in MongoDB

"ModelEvent": {
  "dataSource": "db",
  "public": true,
  "options": {
    "mongodb": {
      "collection": "Event"
    }
  }
},

Notes

Enable ACL in your Loopback project if you haven't yet. To achieve it, create the file server/boot/authentication.js with the following code:

'use strict';

module.exports = function enableAuthentication(server) {
  // enable authentication
  server.enableAuth();
};

Development

Install development dependences from module root directory only if you want to execute module tests

cd node_modules/@aliatech/loopback-component-traceability
npm i --only=dev

Usage

Configure the Traceable mixin in those models that require a traceability. Add this in the model json file, under "mixins":

"mixins": [
  ...,
  "Traceable": true
]

You also can set options:

"mixins": [
  ...,
  "Traceable": {
    "displayProperty": "name", // Property used as display of the object
    "events": {
      "create": true, // Enables automatic event create
      "update": true, // Enables automatic event update
      "remove": true // Enables automatic event remove
    }
  }
]
