安装
npm install node-plug
使用示例：
plugin.js
export const pluginsync = { run() { console.log('plugin sync dijalankan!') },}export const plugincallback = { run() { console.log('plugin callback mulai...') settimeout(() => console.log('plugin callback selesai!'), 15) },}export const pluginpromise = { async run() { console.log('plugin promise mulai...') await new promise((resolve) => settimeout(resolve, 15)) console.log('plugin promise selesai!') },}
main.js
import { addplugin, runplugin, test } from 'node-plug'import { pluginsync, plugincallback, pluginpromise } from './plugin.js'// menambahkan pluginaddplugin(pluginsync)addplugin(plugincallback)addplugin(pluginpromise)// menjalankan pluginrunplugin()// melakukan pengujiantest([ 'plugin sync dijalankan!', 'plugin callback mulai...', 'plugin promise mulai...', 'plugin callback selesai!', 'plugin promise selesai!',])
上面的代码工作正常，但是如果没有 promise 插件，就会发生错误。
由于没有 promise 插件而导致的错误
为什么会出现错误？因为 runplugin 方法返回一个承诺。
解决方案：
为 promise 插件添加同步和回调插件。
plugin.js
const pluginsync = { run() { console.log('plugin sync dijalankan!') },}const plugincallback = { run() { console.log('plugin callback mulai...') },}export const pluginpromise = { async run() { pluginsync.run() plugincallback.run() await new promise((resolve) => settimeout(resolve, 15)) console.log('plugin callback selesai!') },}// atau/*const pluginsync = { run() { console.log('plugin sync mulai...') },}const plugincallback = { run() { console.log('plugin callback mulai...') },}export const pluginpromise = { async run() { pluginsync.run() await new promise((resolve) => settimeout(resolve, 15)) console.log('plugin sync selesai!') plugincallback.run() await new promise((resolve) => settimeout(resolve, 15)) console.log('plugin callback selesai!') },}*/// atau/*const pluginsync = { run() { console.log('plugin sync mulai...') },}const plugincallback = { run() { console.log('plugin callback mulai...') },}export const pluginpromise = { async run() { pluginsync.run() await new promise((resolve) => settimeout(resolve, 15)) console.log('plugin sync selesai!') plugincallback.run() await new promise((resolve) => settimeout(resolve, 15)) console.log('plugin callback selesai!') console.log('plugin promise mulai...') await new promise((resolve) => settimeout(resolve, 15)) console.log('plugin promise selesai!') },}*/
main.js
import { addPlugin, runPlugin, test } from 'node-plug'import { pluginPromise } from './plugin.js'// Menambahkan pluginaddPlugin(pluginPromise)// Menjalankan pluginrunPlugin()// Melakukan pengujiantest([ 'Plugin sync dijalankan!', 'Plugin callback mulai...', 'Plugin callback selesai!',])// atau/*import { addPlugin, runPlugin, test } from 'node-plug'import { pluginPromise } from './plugin.js'// Menambahkan pluginaddPlugin(pluginPromise)// Menjalankan pluginrunPlugin()// Melakukan pengujiantest([ 'Plugin sync mulai...', 'Plugin sync selesai!', 'Plugin callback mulai...', 'Plugin callback selesai!',])*/// atau/*import { addPlugin, runPlugin, test } from 'node-plug'import { pluginPromise } from './plugin.js'// Menambahkan pluginaddPlugin(pluginPromise)// Menjalankan pluginrunPlugin()// Melakukan pengujiantest([ 'Plugin sync mulai...', 'Plugin sync selesai!', 'Plugin callback mulai...', 'Plugin callback selesai!', 'Plugin Promise mulai...', 'Plugin Promise selesai!',])*/
以上就是简单的 Nodejs 插件支持同步、回调、承诺和断言的详细内容，更多请关注创想鸟其它相关文章！
