kwseok / sbt-webpack Goto Github PK

I'm trying to use sbt-webpack in a play 2.5 project. How can I hook sbt-webpack into Play's run task, which starts a dev server? And/or how can I make it run after assets task?

When discovering contexts from Webpack the path isn't recognized as absolute on Windows, meaning that it tries to discover files in (for example) C:\Users\User\appman\C:\Users\User\appman\app\assets rather than C:\Users\User\appman\app\assets.

A patch is WIP.

It'd be nice to have a test suite run automatically to validate pull requests. Travis is free for open source projects and pretty easy to setup. Most of the Lightbend plugins use it, so there's lots of examples as well

We've released a new version of sbt-js-engine to work with newer versions of node and npm

The plugin works, but there are several caveats:

1. The .ts sources are copied to target/web/public/main
2. The suggested config with output.path set to /target/web/webpack makes the file not to be found by routes <script src="@routes.Assets.versioned("webpack/bundle.js")" type="text/javascript"></script>. (workaround: set the path to path.join(__dirname, '/target/web/public/main/javascripts') and use <script src="@routes.Assets.versioned("javascripts/bundle.js")" type="text/javascript"></script>)
3. Now we need to run separated webpack:startWatch command. How can we cause the plugin to run when we build the project?

Dear friends, first of all, thanks for your wonderful work!!
I need the SBT-Webpack Plugin for:

• Compile JSX code to Javascript as defined in webpack.config.js

• Bundle the Javascipt code together

• And execute some scripts(Webpack commands) as defined in package.json

Is this posible with SBT-Webpack Plugin?
Thanks in advance!!

Hi there,

Thanks for writing this plugin, it's saved me heaps of time. I think I may have found an issue with the watch feature.

The issue occurs when I try to reload an sbt play project with this plugin added. I don't have any sbt-webpack specific settings in my build.sbt. I tested and this issue also occurs with sbt-play-webpack.

src$ sbt
[server-play] $ reload
java.util.NoSuchElementException: None.get

I see you have assets in src/main/web:
https://github.com/stonexx/sbt-webpack/tree/master/sbt-webpack-tester/src/main/web/js

https://github.com/sbt/sbt-web says that it looks for

files that are available for processing from src/main/assets

Why are these different? Is there a setting that's different between the two?

Hello and thank you for the plugin.

I am trying to make the webpack run after I modify a .ts file(s), but it does not.

I have in my webpack.config.js:

module: {
		loaders: [
			{
				test: /\.ts$/,
				loader: 'awesome-typescript-loader'
			},
			{
				test: /\.css$/,
				loader: "style-loader!css-loader"
			}
		]
	},

and in build.sbt:

includeFilter in (Assets, webpack) := "*.ts"

also tried:

includeFilter in webpack := "*.ts"

and:

includeFilter in webpack := "*.ts" || "*.css"

nothing triggers the recompile.

Also I am not sure how, but the webpack is resolving the files from <project_folder>/src, and I am not sure why src is there. (I have Play project, where my assets are under app).

This issue makes me have:

entry: '../app/assets/src/app',

instead of:

entry: './app/assets/src/app',

When I run node's webpack from command line - it resolves the files ok.

I like letting webpack-dev-server handle the JS compilation when in development mode. There's a good example of how to do it here: https://github.com/arpossatto/play-webpack-dev-react-boilerplate

I'm trying to add examples of Play using webpack in official Lightbend docs and examples. I have a branch converting one of the templates here:

https://github.com/benmccann/activator-lagom-java-chirper/tree/webpack

For some reason the webpack task is never being called when I use WebKeys.pipeline := WebKeys.pipeline.dependsOn(webpack.toTask("")).value

Why is that syntax used rather than the recommended pipelineStages := Seq(myPipelineTask)?

If I change it to compile in Compile <<= (compile in Compile).dependsOn(webpack.toTask("")) then it works
