我想启动一个vue-cli dev服务器,然后在此构建完成后从节点运行命令。
是否可以从节点脚本运行vue-cli-service serve
,以便一旦开发服务器启动并运行,我就可以收到回调?
答案 0 :(得分:3)
vue-cli-service.js
不返回服务承诺(这将允许您设置完成回调),但是您可以复制脚本(25行)来这样做:
my-vue-cli-service.js:
#!/usr/bin/env node
const semver = require('semver')
const { error } = require('@vue/cli-shared-utils')
const requiredVersion = require('@vue/cli-service/package.json').engines.node
if (!semver.satisfies(process.version, requiredVersion)) {
error(
`You are using Node ${process.version}, but vue-cli-service ` +
`requires Node ${requiredVersion}.\nPlease upgrade your Node version.`
)
process.exit(1)
}
const Service = require('@vue/cli-service')
const service = new Service(process.env.VUE_CLI_CONTEXT || process.cwd())
const rawArgv = process.argv.slice(2)
const args = require('minimist')(rawArgv)
const command = args._[0]
module.exports = () => // <--- add this line to return the service promise
service.run(command, args, rawArgv).catch(err => {
error(err)
process.exit(1)
})
然后,您可以创建另一个使用此副本的脚本,添加一个then
回调以在服务器成功启动时调用:
my-service.js:
#!/usr/bin/env node
const service = require('./my-vue-cli-service')
service().then(result => {
if (result && result.server) { // <--- server started successfully if result.server exists
const {server, url} = result;
console.log('ready');
}
})
请确保更新package.json
以使用新脚本:
package.json:
{
"scripts": {
"serve": "./my-service.js serve"
}
}
