在 Azure 应用程序服务上使用 Express 创建反应应用程序无法启动
create react app with express on azure app service fails to start
我已经部署到 Azure create-react-app，它有一个 server.js 文件用于动态生成 meta tags。
堆栈是 Linux
上的节点 16
在我的启动命令中我有 pm2 start /home/site/wwwroot/server.js --no-daemon
我的server.js如下
const express = require("express");
const path = require("path");
const fs = require("fs");
const PORT = process.env.PORT || 5000;
const app = express();
app.get("/", (req, res) => {
const filePath = path.resolve(__dirname, "index.html");
fs.readFile(filePath, "utf8", (err, data) => {
if (err) {
return console.log(err);
}
data = data.replace(/__META_OG_TITLE__/g, "Home Page").replace(/__META_DESCRIPTION__/g, "Home page description.");
res.send(data);
});
});
app.get("/snp/list", (req, res) => {
const filePath = path.resolve(__dirname, "index.html");
fs.readFile(filePath, "utf8", (err, data) => {
if (err) {
return console.log(err);
}
data = data.replace(/__META_OG_TITLE__/g, "SNP List").replace(/__META_DESCRIPTION__/g, "SNP List description.");
res.send(data);
});
});
app.get("/snp/detail", (req, res) => {
const filePath = path.resolve(__dirname, "index.html");
fs.readFile(filePath, "utf8", (err, data) => {
if (err) {
return console.log(err);
}
data = data.replace(/__META_OG_TITLE__/g, "SNP Detail").replace(/__META_DESCRIPTION__/g, "SNP detail description.");
res.send(data);
});
});
app.use(express.static(path.resolve(__dirname)));
app.listen(PORT, () => {
console.log(`Server is listening on port ${PORT}`);
});
此 server.js 是 index.html 的兄弟姐妹。
我收到 Cannot find module 'express' 错误，这是我的错误日志转储

如果我将启动命令切换为 pm2 serve /home/site/wwwroot --no-daemon --spa 那么一切正常。
并且，如果我发出 node server.js 从构建文件夹本地，那么它再次在 http://localhost:5000/
下完美运行
我花了一整天的时间试图找出可能出了什么问题，任何帮助将不胜感激。
编辑
现在我只是 ftp 将我的构建文件夹中的所有文件发送到 site/wwwroot。在这一点上，我并不担心设置 CI/CD 链，因为我只是首先希望该应用程序 运行.
正在 settings/configuration/general settings/startup 命令下的 Azure 门户中设置启动命令
EDIT-2
我通过 npm install pm2 -g 在本地机器上安装了 pm2，如果我发出命令 pm2 start server.js 然后从构建文件夹安装了 pm2，那么应用程序会成功启动。
我的本地节点版本是v14.5.0
- 当您为 React、Angular 或其他 Node 框架创建生产构建时，文件将放置在
build 或 dist 目录（文件夹）中，具体取决于框架。
- Linux 上的应用服务使用 Oryx 来检测、构建和启动您的应用程序。
- 使用
--spa会自动将所有查询重定向到index.html_
pm2 serve /home/site/wwwroot --no-daemon --spa
- 为了提供构建的内容，您可以执行以下任一操作：
PM2 服务
如果 build 目录中的所有项目都在 wwwroot 中，请将路径更改为 /home/site/wwwroot.
pm2 serve /home/site/wwwroot/build --no-daemon
如果内容在 dist 文件夹下，请确保使用
pm2 serve /home/site/wwwroot/dist --no-daemon
处理文件
创建一个 process.json 或 process.yml ，将其放在 /home/site/wwwroot.
{
"script": "serve",
"env": {
"PM2_SERVE_PATH": './build'
}
"args": '--no-daemon'
}
在 Azure 门户中，转到 配置.=> 常规 并找到 启动命令框并输入process.json =>保存。
更多信息请参考Configure Node.js server , deploy React application in Azure App Service and Using PM2 on App Service Linux
问题的解决方案就在眼前。
我所要做的就是 SSH 到 home/site/wwwroot & npm install express。
一切都与我的 meta tags 动态生成完美配合。
我已经部署到 Azure create-react-app，它有一个 server.js 文件用于动态生成 meta tags。
堆栈是 Linux
上的节点 16在我的启动命令中我有 pm2 start /home/site/wwwroot/server.js --no-daemon
我的server.js如下
const express = require("express");
const path = require("path");
const fs = require("fs");
const PORT = process.env.PORT || 5000;
const app = express();
app.get("/", (req, res) => {
const filePath = path.resolve(__dirname, "index.html");
fs.readFile(filePath, "utf8", (err, data) => {
if (err) {
return console.log(err);
}
data = data.replace(/__META_OG_TITLE__/g, "Home Page").replace(/__META_DESCRIPTION__/g, "Home page description.");
res.send(data);
});
});
app.get("/snp/list", (req, res) => {
const filePath = path.resolve(__dirname, "index.html");
fs.readFile(filePath, "utf8", (err, data) => {
if (err) {
return console.log(err);
}
data = data.replace(/__META_OG_TITLE__/g, "SNP List").replace(/__META_DESCRIPTION__/g, "SNP List description.");
res.send(data);
});
});
app.get("/snp/detail", (req, res) => {
const filePath = path.resolve(__dirname, "index.html");
fs.readFile(filePath, "utf8", (err, data) => {
if (err) {
return console.log(err);
}
data = data.replace(/__META_OG_TITLE__/g, "SNP Detail").replace(/__META_DESCRIPTION__/g, "SNP detail description.");
res.send(data);
});
});
app.use(express.static(path.resolve(__dirname)));
app.listen(PORT, () => {
console.log(`Server is listening on port ${PORT}`);
});
此 server.js 是 index.html 的兄弟姐妹。
我收到 Cannot find module 'express' 错误，这是我的错误日志转储

如果我将启动命令切换为 pm2 serve /home/site/wwwroot --no-daemon --spa 那么一切正常。
并且，如果我发出 node server.js 从构建文件夹本地，那么它再次在 http://localhost:5000/
我花了一整天的时间试图找出可能出了什么问题，任何帮助将不胜感激。
编辑
现在我只是 ftp 将我的构建文件夹中的所有文件发送到 site/wwwroot。在这一点上，我并不担心设置 CI/CD 链，因为我只是首先希望该应用程序 运行.
正在 settings/configuration/general settings/startup 命令下的 Azure 门户中设置启动命令
EDIT-2
我通过 npm install pm2 -g 在本地机器上安装了 pm2，如果我发出命令 pm2 start server.js 然后从构建文件夹安装了 pm2，那么应用程序会成功启动。
我的本地节点版本是v14.5.0
- 当您为 React、Angular 或其他 Node 框架创建生产构建时，文件将放置在
build或dist目录（文件夹）中，具体取决于框架。 - Linux 上的应用服务使用 Oryx 来检测、构建和启动您的应用程序。
- 使用
--spa会自动将所有查询重定向到index.html_
pm2 serve /home/site/wwwroot --no-daemon --spa
- 为了提供构建的内容，您可以执行以下任一操作：
PM2 服务
如果
build目录中的所有项目都在wwwroot中，请将路径更改为/home/site/wwwroot.pm2 serve /home/site/wwwroot/build --no-daemon如果内容在
dist文件夹下，请确保使用pm2 serve /home/site/wwwroot/dist --no-daemon
处理文件
创建一个 process.json 或 process.yml ，将其放在
/home/site/wwwroot.{ "script": "serve", "env": { "PM2_SERVE_PATH": './build' } "args": '--no-daemon' }在 Azure 门户中，转到 配置.=> 常规 并找到 启动命令框并输入
process.json=>保存。
更多信息请参考Configure Node.js server , deploy React application in Azure App Service and Using PM2 on App Service Linux
问题的解决方案就在眼前。
我所要做的就是 SSH 到 home/site/wwwroot & npm install express。
