Custom decorator

You can use the API provided by the system to implement custom functions.

Request decorator

Decorators are called in order when requested

Example:

import {FireCatDecorator} from "fire-cat";

// Verify login
export const AuthLogin = function () {
  return FireCatDecorator.registerImplement(async (ctx, next) => {
    // Simulate parsing user data
    ctx.state.userInfo = {
      id: 1,
      name: 'fake',
      some: 'bar'
    }
    await next()
  })
}

Note⚠️: Be sure to await next() in the async method

Define decorator

This is usually not commonly used, and is generally used by some built-in decorators of FireCat.

Example:

export function Get(path: string) {
  return FireCatDecorator.registerImplement((target, propertyKey, decorator)=> {
    //
  })
}
