Package Exports
- webpack-dev-server-fallback
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (webpack-dev-server-fallback) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
webpack-dev-server-fallback
Use a static directory as a fallback for requests to webpack-dev-server
when the build isn't ready.
Useful in conjunction with HtmlWebpackPlugin to avoid blank screens and timeouts.
Don't use webpack-dev-server
in production. This is for in-between cases.
Install
npm install webpack-dev-server-fallback --save(-dev)
Use
In such as webpack.config.js
:
const webpackDevServerFallback = require('webpack-dev-server-fallback');
module.exports = {
devServer: {
before: webpackDevServerFallback()
}
};
webpackDevServerFallback
takes an options
object with two properties:
wait
: milliseconds to wait for build to be ready before serving fallback (default: 300)directory
: source for fallback files (default: "fallback", is passed toexpress.static
)
module.exports = {
devServer: {
before: webpackDevServerFallback({wait: 1000, directory: 'dist'})
}
};
If you have other business to conduct with devServer.before
:
module.exports = {
devServer: {
before(app, server) {
// ...code, code, code
webpackDevServerFallback()(app, server);
}
}
};
