Collecting un-linked assets with Webpack? - asset-pipeline

I have a directory of assets - favicon, sitemap.xml, etc - which are not referenced by my application, but which should be collected during my webpack build. This is trivial to do with other build tools like Grunt or Gulp, but I'm absolutely stumped on how to get Webpack to do this.

One way to sort of solve this is to use copy-loader. Keep in mind that Webpack is primarily a module bundler so this use case goes beyond it. It's more than fine to use Webpack with some other tools that are better suited for copying files.

SASS Rendering in Go

I am beginning to use Go for web development, but I am having issues with asset management. I would prefer to have a tool like Rails' Asset Pipeline for managing (and compressing) css/js files (as well as SASS), but I am still able to work with css and js files.
While I am able to work with css and js, I am not able to work with SASS. Is there a way to use SASS in a Golang project? I am not using a framework.
Thank you!
I'm not familiar with Ruby on Rails but, I assume, that ruby on rails gave you some sort of tools for managing the source to distribution client-side asset transition (polyfills, transpiling, minification, compiling of SASS/SCSS to CSS, compiling of XScript to JavaScript ... etc).
While a web development framework might do that to try and ease in developers quickly (I assume rails does that, not ruby) its not exactly the way Go does stuff.
Go is a language, not a framework + language, just a compiler, a few build tools and a set of standards for how to write, test, document and indent stuff (with the indent,test and document part being optional).
A go server, at least the way I built servers with go, is somewhat decoupled from the client. It server static assets when they are needed (e.g. it serves the minified JavaScript and the stylsheets and the html, and jsons with info from the databases... etc), but it doesn't really care about what those are, its a server. The go toolchain is made for building golang applications (e.g. said server), but its not made for building client-side web applications (those consisting of js, css and html).
Now, you may use a framework similar to rails written in go that helps "pack up" css, js, html. But I'm unaware if there are any.
You may use a compiler which turns go into client-side code (i.e. javascript) https://github.com/gopherjs/gopherjs , if you enjoy the go toolchian and want to use it for client-side development. But, go-like performance isn't something this gives you AND you are working with a subset of go. Its really just a different way to write javascript.
However, what you most likely need in your case is a "build-chain" for your client side. Here there are 3 tools which (in my opinion) stand out in 2016:
npm
webpack
bower
I could write an essay about using this tools but here's the summary:
Webpack is used to create a "pipeline" for your code which does thing like, calling babel on javascript, compiling sass to css, minifying assets, allowing js to be written with import syntax... etc, really, its a swis army knife in your js development arsenal and probably matches the functionality of whatever you were using before.
Npm is the node package manager BUT even if you are not using node for your server. It can be useful to keep tracks of dependencies for building your application (like webpack) and for downloading modules. Its also useful for running various scripts and deployment, its a bit of an overkill to use both npm and weback though you will probably have an easier time setting up the webpack enviornment if you have a package.json (config file for npm) with each of your project.
Bower is one I actually don't use for small projects. But its basically a repository for javascript libraries (among other things), so you can easily say, write "bower install jquery" and you've downloaded jQuery for your current project.
Again, there are many other tools out there, these are just some of the ones I like, but, check some of them out. They can help you replaces your previous pipeline. Don't think of client and server side code as being the same, they are decoupled and having a strong separation between them might help you a lot.

How to use webpack for development Angular2 / typescript without running build each time?

I am using ASP.Net Core, Angular2 and Typescript and connected all together with webpack using the tutorial from Angular2 team here. That all seems to work but now I need to build each time I change a file.
Original tutorial uses system.js and that loads tons of files of course, but I just use static file middleware and no build is required for development. That is very convinient, but I cannot figure out how to do the same with webpack. It seems that webpack can only bundle everything together without an option to just load everything separately so I need to run the build each time.
Is it possible to do something so that webpack "expands" the bundle in some easy way?
P.S. I would like not to use webpack dev server and some auto-build on save and so on since the complexity is rather high alredy. So ideal solution is that I have bundles for production but direct code loaded for development like in good old days with standard mvc bundling.
Really, the best way would be to use webpack dev server. There's really not much setup involved, it's just a different command you run instead of webpack:
npm install webpack-dev-server
webpack-dev-server webpack.config.js
Then you just point script sources to http://localhost:8080/webpack-dev-server/your-bundle-name.js" in your application` tags.
This is by far the best option as you get instant incremental recompile and live-reload.
While I would strongly encourage you to use webpack-dev-server you can also just use plain webpack in watch mode:
webpack ---watch
There is no way to "expand the bundle" (and really no need to). In all likelyhood you are using webapack for more than just bundling, so you'd still require to re-build if you change a typescript file, for example. Webpack dev server or webpack in watch mode do very quick incremental compiles, and most people will just leave them running while developing.

How can I watch imported SASS files using Webpack?

The problem I am encountering a great number of imported files. I am trying to slowly inject webpack into a legacy site. There are many global stylesheets:
require('../../../Content/Ones/_forms.scss');
require('../../../Content/Ones/_grid.scss');
require('../../../Content/Ones/_panels.scss');
require('../../../Content/Ones/one.scss');
require('../../../Content/Ones/_grid_tools.scss');
Is there a way to avoid this? I might be just looking at this from the wrong angle because I can't seem to find a question that matches my use case.
Please advise, Thanks!
The SASS files you import (whether you import them from a JS file or another SASS file) are part of your webpack dependency tree, so they should all be watched automatically. If they're not, would you mind adding some more info to your question about your app structure and webpack config?
As for reducing the number of global SASS imports, there are a few ways to do that, but making a good choice here really depends on how your app is structured.
Side question: Is there a reason you're adding webpack to this site? Anything in particular you're hoping to gain? I ask because if it's not a component-based SPA, you might not be getting very much out of webpack, and it may not be worth the trouble.

Aurelia Skeleton-Navigation Will Not Load After Bundling

So I am using the Aurelia skeleton-navigation starter as recommended. However, when I run the gulp bundle task the application will no longer load the main UI, it get's stuck on the spinner/loading page. I found this issue but even after installing the jspm beta it still doesn't seem to be resolved. Anyone had any luck? For what it is worth, I do not even see an aurelia.js bundle being created in the /dist directory so the 404 certainly makes sense in that respect.
So I have a fix, I am not thrilled with it though. It seems if you run bundle then run gulp watch to start the webserver, that the bundled files get wiped out from the dist folder. Running gulp watch in one command window and gulp bundle in another results in it working correctly as the bundled js is there at that point. I hope for a better fix from someone, this seems kind of hacky.

What's the point of letting server to compile and minify assets when we can do it manually?

Disclaimer: I know almost nothing about servers. Sorry if this question doesn't make sense in the first place.
I'm building my project in Node.js with CoffeeScript and Stylus and some other compiled stuff. Until now I've made a script to compile my code into regular JavaScript and CSS, then run it. I'm planning to upload the compiled assets to the production server, so there's no trace of CoffeeScript or Stylus anywhere afterward.
But I know that it's possible to directly run server-side CoffeeScript (coffee app.coffee), and that there are middlewares in Node which compile and minify client-side CoffeeScript and Stylus on the fly.
My question is, why let the server do it each time, instead of compiling the code ourselves? Wouldn't the first option add more strain on the server for no reason?
Thanks.
It would not add strain on the server. An educated guess would tell me that one it compiles and minifies your CoffeeScript it caches the result for each subsequent request.
Manual processes introduce risk and probability of error.
