go-admin

Architecture

Business Features

• User management
• Role management

Other Features

Authentication

• Log in by LDAP
• After logged in, get all privileges based on roles of that user

Middleware for Authorization

Features

• Integrate authorization checks into HTTP middleware
• Ensure authorization is enforced on API endpoints
• Authorization: Separate the "read" and "write" permissions for 1 role, using bitwise. For example:
  • 001 (1 in decimal) is "read" permission
  • 010 (2 in decimal) is "write" permission
  • 100 (4 in decimal) is "delete" permission
  • "read" and "write" permission will be "001 | 010 = 011" (011 is 3 in decimal)
• Some other standard features
  • config: load config from yaml files
  • health check: to check health of SQL
  • logging: can use logrus or zap to log, support to switch between logrus or zap
  • log tracing by at the middleware the http request and http response

Middleware log tracing

• Log important information about incoming requests, outgoing responses, and the operations performed by the application.
