我正在基于Koa template的通用模式下以Koa作为API /控制器运行Nuxt。我正在部署到Heroku。 API在本地运行良好,但在生产中返回404。我认为该应用程序在部署时会以SPA的形式运行,因为其他所有功能都可以正常运行。
这是我的服务器/index.js
const Koa = require('koa')
const consola = require('consola')
const Router = require('koa-router');
const { Nuxt, Builder } = require('nuxt')
const api = require('./api');
console.log('server works'); // ------> This line gets ignored by the Heroku console
const app = new Koa()
const router = new Router();
// Import and Set Nuxt.js options
const config = require('../nuxt.config.js')
config.dev = app.env !== 'production'
router.use('/api', api.routes(), api.allowedMethods());
app.use(router.routes());
async function start () {
// Instantiate nuxt.js
const nuxt = new Nuxt(config)
const {
host = process.env.HOST || '127.0.0.1',
port = process.env.PORT || 3000
} = nuxt.options.server
// Build in development
if (config.dev) {
const builder = new Builder(nuxt)
await builder.build()
} else {
await nuxt.ready()
}
app.use((ctx) => {
ctx.status = 200
ctx.respond = false // Bypass Koa's built-in response handling
ctx.req.ctx = ctx // This might be useful later on, e.g. in nuxtServerInit or with nuxt-stash
nuxt.render(ctx.req, ctx.res)
})
app.listen(port, host)
consola.ready({
message: `Server listening on http://${host}:${port}`, // ------> Neither this line appears in Heroku console
badge: true
})
}
start()
Procfile
web: nuxt start
来自package.json的脚本
"scripts": {
"dev": "cross-env HOST=192.168.1.65 NODE_ENV=development nodemon server/index.js --watch server ",
"build": "nuxt build",
"start": "cross-env NODE_ENV=production node server/index.js",
"generate": "nuxt generate",
"test": "ava",
"test:unit": "cross-env TEST=unit ava --config unit.config.js",
"test:e2e": "cross-env TEST=e2e ava --config e2e.config.js",
"heroku-postbuild": "nuxt build"
}
我认为我在阅读all these部署文档后并没有看到明显的错误,但是却得到了nu(x)ts。
谢谢。
我没有任何问题,附加了package.json
,server/index.js
文件和Heroku环境设置。您可以从here
