我正在努力寻找一个如何设置webpack包的输出文件的公共路径的示例.
If you don’t know the publicPath while compiling, you can omit it and
set__webpack_public_path__
on your entry point.
像这样:
__webpack_public_path__ = myRuntimePublicPath
有人会非常友好地创建一个JSFiddle示例如何做到这一点?
最佳答案 近两年后没有任何改变.在运行时找到为webpack设置公共路径的示例仍然令人惊讶地困难.
先决条件
> webpack 4.5.0
>一个足以利用代码拆分的应用程序
为简单起见,假设我们的html位于index.html,app入口点为app.js
一个有效的例子
的index.html
<!DOCTYPE html>
<html lang="en">
<head></head>
<body>
<div id="app"></div>
<script type="application/javascript">
window.resourceBasePath = '/path/to/scripts/on/server/';
</script>
<script type="application/javascript" src="/path/to/scripts/on/server/app.js"></script>
</body>
</html>
app.js
// it is important to set global var before any imports
__webpack_public_path__ = window.resourceBasePath;
import React from 'react';
import ReactDOM from 'react-dom';
import {store, history} from './store';
const render = () => {
import('./root').then((module) => {
const Root = module.default;
ReactDOM.render(
<Root
store={store}
history={history}
/>,
document.getElementById('app'),
);
});
};
render();
if (module.hot) {
module.hot.accept('./root', render);
}
一个不起作用的例子
Webpack publicPath documentation说仅仅设置一个具有正确名称的全局变量就足够了.我这样做了:
的index.html
<!DOCTYPE html>
<html lang="en">
<head></head>
<body>
<div id="app"></div>
<script type="application/javascript">
__webpack_public_path__ = '/path/to/scripts/on/server/';
</script>
<script type="application/javascript" src="/path/to/scripts/on/server/app.js"></script>
</body>
</html>
app.js
import React from 'react';
import ReactDOM from 'react-dom';
import {store, history} from './store';
const render = () => {
import('./root').then((module) => {
const Root = module.default;
ReactDOM.render(
<Root
store={store}
history={history}
/>,
document.getElementById('app'),
);
});
};
render();
if (module.hot) {
module.hot.accept('./root', render);
}
在这种情况下,我的应用程序无法在控制台中抱怨它无法将当前路径中的0.js加载到index.html.这意味着设置公共路径没有任何影响.
