Procfile 在 Heroku 上部署 Node.js 網站

Question

我有一個應用程序，它在本地工作。

npm run serve

我嘗試將 node.js 測試應用程序部署到 Heroku，但出現錯誤。 我應該在我的 Procfile 中寫什么。

錯誤：

npm 錯誤！ 缺少腳本：開始

包.json

{
    "name": "demo",
    "version": "0.1.0",
    "description": "",
    "engines": {
        "node": "14.17.0",
        "npm": "6.14.15"
    },
    "main": "index.ts",
    "scripts": {
        "build": "webpack",
        "serve": "webpack-dev-server --open",
        "serve:external": "webpack-dev-server --host 0.0.0.0"
    },
    "author": "",
    "license": "0BSD",
    "devDependencies": {
        "@getify/eslint-plugin-proper-ternary": "^3.0.1",
        "@types/file-saver": "^2.0.5",
        "node-sass": "^4.13.1",
        "sass-loader": "^8.0.2",
        "style-loader": "^1.1.3",
        "ts-loader": "^6.2.1",
        "typescript": "^3.8.3",
        "webpack": "^4.42.1",
        "webpack-cli": "^3.3.11",
        "webpack-dev-server": "^3.10.3"
    },
    "dependencies": {
        "@navvis/ivion": "file:navvis-ivion-10.3.2.tgz",
        
    }
}

所以，我寫了 Procfile

web: npm run serve  // I am not sure if it is OK:

文件夾：

node_modules
Src
   -> Index.ts
Procfile
package.json


heroku logs --tail

確保Procfile看起來像：

web: npm start

如果您使用的是 git； 記得添加、提交和推送您的更改。
