install

$ npm install --save chrome-extension-core

Usage

Init Event

import { Event } from 'chrome-extension-core';

type EventInfo = {
  anyEvent: string;
};

type EventResponse = {
  anyEvent: number;
};

export const chromeEvent = new Event<EventInfo, EventResponse>('scope');

Use Event

chromeEvent.on('anyEvent', (val) => {
  console.log(val); // test test test
  return { message: 'success', success: true, data: 123 };
});

chromeEvent.emit('anyEvent', 'test test test').then((res) => {
  console.log(res); //  { message: 'success', success: true, data: 123 }
});

Init Store

import { Store } from 'chrome-extension-core';

export type StorageInfo = {
  anyStore: boolean;
};

export const defaultValue: StorageInfo = {
  anyStore: false,
};

export const chromeStore = new Store<StorageInfo>(
  chrome.storage.local,
  defaultValue,
  { scope: 'scope' }
);

Use Store

chromeStore.get('anyStore').then((res) => {
  console.log(res); // false
});
chromeStore.addWatcher((data) => {
  console.log(data); // { anyStore: { newValue: true, oldValue: false }}
});
chromeStore.set('anyStore', true);
chromeStore.get('anyStore').then((res) => {
  console.log(res); // true
});

Init Proxy Request

• background(service worker)

const directRequest = initProxyRequest({
  scope: 'your-scope', // Optional, the scope of the proxy request
  options: {
    // umi-request configuration options
    // ...
  },
});

// Make a directRequest
directRequest({
  url: '/api/data',
  method: 'GET',
}).then((response) => {
  console.log('Response:', response);
});

Use Proxy Request

• content script

const proxyRequest = createProxyRequest({
  scope: 'your-scope', // Optional, the scope of the proxy request, same as initPRoxyRequest
});

// Make a proxyRequest
proxyRequest({
  url: '/api/data',
  method: 'GET',
}).then((response) => {
  console.log('Response:', response);
});

// Or use shorthand methods
proxyRequest.get('/api/data', { params: { key: 'value' } }).then((response) => {
  console.log('Response:', response);
});

proxyRequest.post('/api/data', { data: { key: 'value' } }).then((response) => {
  console.log('Response:', response);
});
