本页面介绍 /ae/src/index.js|ts 文件,它在 quasar dev 和 quasar build 时执行。这是你修改构建以满足 App Extension 需求的主要入口。例如,注册 boot 文件、修改 Vite 配置、注册 CSS、注册 UI 组件、注册 Quasar CLI 命令等。
文件的基本结构示例:
import { defineIndexScript } from '#q-app'
// can be async
export default defineIndexScript(api => {})API 参数
api.ctx
与 /quasar.config 文件中的 ctx 相同。帮助你根据 quasar dev 或 quasar build 运行的上下文做出决策。
示例:你可能只想在 Electron 模式下使用某个 api 方法。
if (api.ctx.dev && api.ctx.mode.electron) {
api.beforeDev(api => {
// do something when running quasar dev and
// with Electron mode
})
}{
dev: true,
prod: false,
mode: { spa: true },
modeName: 'spa',
target: {},
targetName: undefined,
arch: {},
archName: undefined,
bundler: {},

}
}
}api.extId
包含此 App Extension 的 ext-id(字符串)。
api.prompts
一个包含此 App Extension 安装时用户回答的对象。更多关于 prompts 的信息,请查看 Prompts API。
api.resolve
解析运行此 App Extension 的应用中的路径。无需自己导入 path 并解析路径。
// resolves to root of app
api.resolve.app('src/my-file.js')
// resolves to root/src of app
api.resolve.src('my-file.js')
// resolves to root/public of app
api.resolve.public('my-image.png')
// resolves to root/src-pwa of app
api.resolve.pwa('some-file.js')
// resolves to root/src-ssr of app
api.resolve.ssr('some-file.js')
// resolves to root/src-cordova of app
api.resolve.cordova('config.xml')
// resolves to root/src-electron of app
api.resolve.electron('some-file.js')
// resolves to root/src-electron of app
api.resolve.electron('some-file.js')
// resolves to root/src-bex of app
api.resolve.bex('some-file.js')api.appDir
包含运行此 App Extension 的应用根目录的完整路径(字符串)。
api.logger
一个作用域为当前 App Extension 的日志工具。每个方法的输出都会标记 AE (<extId>),方便用户识别哪行日志来自哪个扩展。
api.logger.log('hello') // 绿色横幅行
api.logger.warn('careful') // 黄色横幅警告
api.logger.fatal('boom') // 红色横幅错误;以退出码 1 退出
api.logger.tip('try foo') // TIP 标签提示行
api.logger.info('synced') // INFO 标签行
api.logger.info('synced', 'SYNC') // 自定义标签文本替代 INFO
api.logger.success('built')
api.logger.error('oh no')
api.logger.warning('hmm')
const finish = api.logger.progress({
tool: 'ssg',
waitAction: 'building',
doneAction: 'built'
})
// ...稍后
finish() // 打印 DONE 行及耗时
api.logger.dot // 辅助方法打印的圆点字符api.hasTypescript
/**
* @return {Promise<boolean>} host project has TypeScript active or not
*/
await api.hasTypescript()api.getStorePackageName
/**
* @return {Promise<string|undefined>} 'pinia' | 'vuex' | undefined
*/
await api.getStorePackageName()api.getNodePackagerName
/**
* @return {Promise<'npm' | 'yarn' | 'pnpm' | 'bun'>}
*/
await api.getNodePackagerName()api.compatibleWith
通过 semver 条件确保 App Extension 与宿主应用中安装的包兼容。
如果不满足 semver 条件,@quasar/app 将报错并停止执行。
semver 条件示例:'1.x || >=2.5.0 || 5.0.0 - 7.2.3'。
/**
* @param {string} packageName
* @param {string} semverCondition
*/
api.compatibleWith('@quasar/app-vite', '3.x')api.compatibleWith('@quasar/app-vite', '^3.0.0-rc.1')api.hasPackage
通过 semver 条件判断宿主应用中是否安装了某个包。
semver 条件示例:'1.x || >=2.5.0 || 5.0.0 - 7.2.3'。
/**
* @param {string} packageName
* @param {string} (optional) semverCondition
* @return {boolean} package is installed and meets optional semver condition
*/
if (api.hasPackage('vuelidate')) {
// hey, this app has it (any version of it)
}
if (api.hasPackage('quasar', '^2.0.0')) {
// hey, this app has Quasar UI v2 installed
}api.hasExtension
检查另一个 app extension 是否已通过 npm 安装且 Quasar CLI 已调用它。
/**
* Check if another app extension is installed
*
* @param {string} extId
* @return {boolean} has the extension installed & invoked
*/
if (api.hasExtension(extId)) {
// hey, we have it
}api.getPackageVersion
获取宿主应用中某个包的版本。
/**
* @param {string} packageName
* @return {string|undefined} version of app's package
*/
console.log(api.getPackageVersion(packageName))
// output examples:
// 1.1.3
// undefined (when package not found)api.extendQuasarConf
扩展 quasar.config 文件
extendQuasarConf: Callback<
(
cfg: QuasarConf,
api: IndexAPI
) => QuasarConf | void | Promise<QuasarConf | void>
>
// Example:
api.extendQuasarConf((conf, api) => {
// Do something with quasar.config file.
// Optionally, return a config that will be merged
// with the default one
})注册 boot 和 css 文件
import { defineIndexScript } from '#q-app'
export default defineIndexScript(api => {
api.extendQuasarConf((conf, api) => {
return {
// make sure my-ext boot file is registered
boot: ['~quasar-app-extension-my-ext/src/runtime/boot.register.js'],
// make sure my global my-ext css goes through Vite
css: ['~quasar-app-extension-my-ext/src/runtime/style.sass']
}
})
// Alternatively, directly touch the "conf" param
api.extendQuasarConf((conf, api) => {
// make sure my-ext boot file is registered
conf.boot.push('~quasar-app-extension-my-ext/src/runtime/boot.register.js')
// make sure my global my-ext css goes through Vite
conf.css.push('~quasar-app-extension-my-ext/src/runtime/style.sass')
})
})TIP
注意路径前面的波浪号(~)。它告诉 Quasar CLI 该路径是 node_modules 中的依赖,而不是相对于 App Extension index 脚本文件的相对路径。
api.registerCommand
注册一个命令,可通过 quasar run <ext-id> <cmd> [...args] 使用。
/**
* @param {string} commandName
* @param {function} fn
* (processArgv: string[]) => ?Promise
*/
api.registerCommand('start', processArgv => {
// do something here
// this registers the "start" command
// and this handler is executed when running
// $ quasar run <ext-id> start
})定义和解析参数的示例:
// import { parseArgs } from 'node:util'
api.registerCommand('fun', () => {
try {
const { values, positionals } = parseArgs({
options: {
name: { type: 'string', short: 'n' },
debug: { type: 'boolean' }
},
strict: true,
allowPositionals: true
})
console.log(values, positionals)
} catch (err) {
console.error(err.message)
}
})api.registerDescribeApi
为 quasar describe 命令注册一个 API 文件。
/**
* @param {string} name
* @param {string} relativePath
* (relative path starting from the file where you have this call)
*/
api.registerDescribeApi(
'MyComponent',
'./relative/path/to/my/component/file.json'
)上面的代码将响应 quasar describe MyComponent 命令。
关于此类 JSON 文件的语法,请查看项目目录中的 /node_modules/quasar/dist/api。注意你的 JSON 必须包含 type 属性(“component”、“directive”、“plugin”)。例如:
{
"type": "component",
"props": {
},
...
}TIP
你可能还想看看 Quasar JSON API Schema 页面。
TIP
始终使用 quasar describe 命令测试以确保语法正确且没有错误。
api.getPersistentConf
获取此扩展的内部持久化配置。如果没有则返回空对象。
/**
* @return {object} cfg
*/
api.getPersistentConf()api.setPersistentConf
设置此扩展的内部持久化配置。如果已存在则会被覆盖。
/**
* @param {object} cfg
*/
api.setPersistentConf({
// ....
})api.mergePersistentConf
深度合并到此扩展的内部持久化配置中。如果扩展还没有设置任何配置,这本质上等同于首次设置。
/**
* @param {object} cfg
*/
api.mergePersistentConf({
// ....
})api.beforeDev
在 quasar dev 命令运行前准备外部服务,例如启动后端或应用依赖的其他服务。
可以使用 async/await 或直接返回 Promise。
/**
* @param {function} fn
* (api, { quasarConf }) => ?Promise
*/
api.beforeDev((api, { quasarConf }) => {
// do something
})api.afterDev
在 Quasar 开发服务器启动后运行钩子(quasar dev)。此时开发服务器已启动,你可以对其进行操作。
可以使用 async/await 或直接返回 Promise。
/**
* @param {function} fn
* (api, { quasarConf }) => ?Promise
*/
api.afterDev((api, { quasarConf }) => {
// do something
})api.beforeBuild
在 Quasar 为生产环境构建应用之前运行钩子(quasar build)。此时 dist 目录尚未创建。
可以使用 async/await 或直接返回 Promise。
/**
* @param {function} fn
* (api, { quasarConf }) => ?Promise
*/
api.beforeBuild((api, { quasarConf }) => {
// do something
})api.afterBuild
在 Quasar 为生产环境构建应用之后运行钩子(quasar build)。此时 dist 目录已创建,你可以对其进行操作。
可以使用 async/await 或直接返回 Promise。
/**
* @param {function} fn
* (api, { quasarConf }) => ?Promise
*/
api.afterBuild((api, { quasarConf }) => {
// do something
})api.onPublish
如果请求了发布(quasar build -P),在 Quasar 为生产环境构建应用且 afterBuild 钩子(如果指定了)执行完毕后运行此钩子。
可以使用 async/await 或直接返回 Promise。
/**
* @param {function} fn
* () => ?Promise
* @param {object} opts
* * arg - argument supplied to "--publish"/"-P" parameter
* * distDir - folder where distributables were built
*/
api.onPublish((api, opts) => {
