Question

我正在尝试通过以下方式部署Sapper构建的应用程序 @now-node。任务基本上是部署具有依赖项的Polka服务器，并静态地提供static /和client /文件。我已经设法通过includeFiles包含Lambda所需的文件，但是现在我在日志中看到该构建器忽略package.json中描述的依赖项。确切的消息是

Starting server on port 3000
Cannot find module 'sirv'
Did you forget to add it to "dependencies" in `package.json`?

但是我在构建日志中看到未收集依赖项。源文件中同时存在package.json和package-lock.json。

对于如何解决此问题，我将不胜感激。

我到达的now.json配置看起来像这样：

{
    "version": 2,
    "name": "experimental-sapper",
    "builds": [
        {
            "src": "__sapper__/build/index.js",
            "use": "@now/node",
            "config": {
                "includeFiles": [
                    "../build/**",
                    "../../static/**"
                    ]
            }
        },
        {
            "src": "static/**",
            "use": "@now/static"
        },
        {
            "src": "__sapper__/build/client/**",
            "use": "@now/static"
        }
    ],
    "routes": [
        { "src": "/(.*(\\.css)|(\\.json)|(\\.png))", "dest": "/static/$1" },
        { "src": "/client/(.*)", "dest": "/__sapper__/build/client/$1" },
        { "src": "/(.*)", "dest": "/__sapper__/build/index.js" }
    ],
    "alias": "..."
}

src / server.js看起来像这样（在汇总捆绑之前）：

import sirv from 'sirv';
import polka from 'polka';
import compression from 'compression';
import * as sapper from '@sapper/server';
const { PORT, NODE_ENV } = process.env;
const dev = NODE_ENV === 'development';
const app = polka() // You can also use Express
    .use(compression({ threshold: 0 }));
if (dev) {
    app.use(sirv('static', { dev }));
}
app.use(sapper.middleware())
    .listen(PORT, err => {
        if (err) console.log('error', err);
    });
export default app.handler;

然后package.json也很标准：

  "description": "TODO",
  "version": "0.0.1",
  "scripts": {
    "dev": "sapper dev",
    "build": "sapper build --legacy",
    "export": "sapper export --legacy",
    "start": "node __sapper__/build",
    "cy:run": "cypress run",
    "cy:open": "cypress open",
    "test": "run-p --race dev cy:run"
  },
  "dependencies": {
    "compression": "^1.7.1",
    "express": "^4.17.1",
    "polka": "^0.5.0",
    "postcss-define-property": "^0.5.0",
    "sirv": "^0.4.0"
  },
  "devDependencies": {
    ...
  },
  "browserslist": "last 2 versions"
}

谢谢！

对于遇到此问题的任何人，解决方案是在https://www.npmjs.com/package/now-sapper使用now-sapper构建器

该站点上有说明，但是本质上您需要如上所述导出您的处理程序，然后让构建器完成其余工作。到目前为止，有一些复杂之处，这意味着仅节点构建器将无法正常工作。

您现在的配置应如下所示：

{
  "version": 2,
  "builds": [
    {
      "src": "package.json",
      "use": "now-sapper"
    }
  ]
}

从README链接了一个演示项目，这是一个基本的Sapper模板，具有现在所需的配置。

对于导出的应用程序，请注意@now/static。

now-cli部署不会建立package.json依赖项
