Question

我正在构建一个简单的应用，该应用使用Nact库演示演员模型。

我现在要处理的错误是：

未捕获的TypeError：无法解析模块说明符“ nact”。相对引用必须以“ /”、“./”或“ ../”开头

这是package.json：

 {
  "name": "actor-model-with-nact-demo-020120",
  "version": "1.0.0",
  "description": "Adam's Actor Model with Nact Demo",
  "main": "server.js",
  "dependencies": {
    "express": "^4.17.1",
    "nact": "^7.2.2",
    "nodemon": "^2.0.2"
  },
  "devDependencies": {},
  "scripts": {
    "dev": "nodemon ./server.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "Adam Dudley",
  "license": "MIT"
}

这是server.js：

const express = require('express')
const path = require('path')

const app = express()
const port = process.env.PORT || '8000'

app.use(express.static(__dirname + '/public'))
app.use('/static', express.static('./static/'))

app.get('/static', function(req, res) {
  res.sendFile(path.join(__dirname + '/static/app.js'))
})

app.get('/', function(req, res) {
  res.sendFile(__dirname + '/public/views/index.html')
})

app.listen(port, () => {
  console.log(`Listening to requests on http://localhost:${port}`)
})

这是index.html：

  <!DOCTYPE html>
    <html lang="en">
      <head>
        <meta charset="UTF-8" />
        <meta name="viewport" content="width=device-width, initial-scale=1.0" />
        <meta http-equiv="X-UA-Compatible" content="ie=edge" />
        <title>Adam's Actor Model with Nact Demo</title>
      </head>
      <body>
        <h1>Adam's Actor Model with Nact Demo</h1>
        <script src="static/app.js" type="module"></script>
      </body>
    </html>

这是app.js：

import { start, dispatch, stop, spawnStateless } from 'nact'

const system = start()

const greeter = spawnStateless(
  system,
  (msg, ctx) => console.log(`Hello ${msg.name}`),
  'greeter'
)

dispatch(greeter, { name: 'World!' })

作者在这里。我不太清楚这里的确切问题，但是就目前而言，Nact仅在服务器端得到正式支持。您可能使其能够在浏览器中运行，但是您可能必须填充setImmediate才能这样做。

由于Nact是commonjs模块，因此您需要使用诸如Parcel或Webpack之类的捆绑程序，才能将库转换为适当的模块格式。
