Question

我运行create-react-app然后切换到目录并运行npm start。只是想知道如何指定一个不同于index.js的文件来启动服务器

这是我的package.json文件：

$servername = "localhost";
$username = "-";
$password = "-";
$database = "-";
$link = mysqli_connect($servername, $username, $password, $database);

if (!$link) {
die(mysqli_error());
}

$sql = "SELECT UserClassName FROM UserInfo1 WHERE UserEmail = '". mysqli_real_escape_string($link, $_SESSION['useremail']) . "'";

if (!$sql) {
die(mysqli_error());
}

$result = mysqli_query($link, $sql);

if (!$result) {
die(mysqli_error());
}

?>
<script>
function getclassname() {
    return document.getElementById("UserClassName").innerHTML = "<?php echo 
$result ?>";
    }
</script>


<html>
<body onload="getclassname(); getcurrentlevel();">
<h1 class="text-center" id="UserClassName" name="UserClassName"><b>Welcome Enviroquest Research Team!</b></h1>
</body>
</html>

我尝试过改变：

{
 "name": "todo",
 "version": "0.1.0",
 "private": true,
 "dependencies": {
   "react": "^16.2.0",
   "react-dom": "^16.2.0",
   "react-scripts": "1.1.1"
 },
 "scripts": {
   "start": "react-scripts start",
   "build": "react-scripts build",
   "test": "react-scripts test --env=jsdom",
   "eject": "react-scripts eject"
 }
}

到

"start": "react-scripts start",

但那些不能工作

查找并编辑 package.json 文件。例如：

{
  "name": "build",
  "version": "0.0.1",
  "scripts": {
    "start": "node different-file.js"
  }
}

npm开始如何指定index.js以外的启动文件
