axios-api-gen v0.1.2

axios-api-gen

English｜繁體中文

This package is generate API from path definition, it is based on axios and it can integrate perfectly with mswx(mock service worker extension).

Install

$ npm i axios-api-gen

Basic usage

define endpoints. (api.ts)

import { METHOD, generateApi, type Endpoints } from 'axios-api-gen';

const endpoints = {
	getUsers: '/users',
	createUser: {
		method: METHOD.POST,
		path: '/users'
	},
	updateUser: {
		method: METHOD.PATCH,
		path: '/users/:id'
	},
	deleteUser: '/users/:id'
};

// type checking is optional.
const checkEndpoints: Endpoints = endpoints;

export default generateApi(endpoints);

Basic usage:

import api from './api'
api.getUsers().then((res) => {
    console.log(res)
})

Auto-complete

Do not directly assign the type when defining endpoints, as this may cause your IDE unavailable to auto-complete. If you want type-checking, please refer to the above example.

generateApi options

The interface is defined as follows.

interface generateApiOptions {
  axiosInstance?: AxiosInstance
  beforeHandler?: () => void
  afterHandler?: () => void
}

axiosInstance

You can customize axios instance, e.g.

import axios from 'axios';

const axiosInstance = axios.create({
	baseURL: import.meta.env.VITE_API_PREFIX,
	headers: {
		'Content-Type': 'application/json'
	}
});

// skip endpoint definition

export default generateApi(endpoints, {
	axiosInstance
});

beforeHandler

A hook for before request.

export default generateApi(endpoints, {
	beforeHandler() {
		console.log('before');
	}
});

afterHandler

A hook for request finished.

export default generateApi(endpoints, {
	afterHandler() {
		console.log('after');
	}
});

Integrate mswx

mswx is an extension of mock service worker, which is more convenient to use and has middleware features.

example:

import api from '@/api';
import { rest } from 'mswx';

export const handlers = [
	rest.define(api.getUsers, async (req, res, ctx) => {
		return res(ctx.status(200));
	})
];

Why does this work?

Because each API not only can call but also has two properties (method, path), for example:

console.log(api.getUsers.method); // output: GET
console.log(api.getUsers.path);   // output: /users
