Detailed explanation of building permission management system in express in nodejs

This article mainly introduces the detailed explanation of express's permission management system. The editor thinks it is quite good. Now I will share it with you and give you a reference. Let’s follow the editor and take a look.

Permission management is a common component in the management system. It is usually necessary to define resources and allocate resources to users. This is achieved by determining whether the user has permission to add, delete, modify, and check.

Original intention:

There are more than 20 large and small projects developed using express, and each of the previous projects existed independently. Recently, the leader suggested integrating these small projects into a large platform, granting permissions to various departments, and allowing them to operate on one platform. The benefits of doing so are firstly to facilitate project management, and secondly to save development costs. But it seems that there is not much information on using nodejs for permission management at present. I am sharing it here for reference only.

At first, I wandered among the node_acl, Connect Roles, and rbac frameworks, and finally chose the node_acl framework, but node_acl only helps you with part of the permission management work, and only saves users, roles, and resources. The relationships between users, roles, and resources themselves are not saved. What we have to do is to complete the addition, deletion, modification, and check of users, roles, and resources, and it will be a complete permission management system.

Expected results:

After the super administrator logs in, he can perform all operations and see all menu bars;
Ordinary users only have partial permissions after logging in. Only part of the menu bar or action buttons are visible.

Main modules:

• express: node framework

• express-hbs: template engine

• node_acl: the core of the permission management system

• mongodb: database

• sails-mongodb: connection mongodb's engine

Front-end:

Amaze ui, angular, Z-Tree

Source code address: https:// github.com/wuwanyu/aclDemo

Running prerequisites:

Install mongodb database

Run

1. Data preparation

(1) Copy the contents of the sql folder in the source code directory to the bin directory of the mongodb installation directory
(2) Enter the bin directory of the mongodb installation directory using the command line and run mongorestore -d acltest acltest.dmp/acltest, import data into acltest table

2. Install dependent packages: npm install

3. Run: npm start

4. Browse Server input: http://localhost:3000 (username/password: admin/admin or user/123)
