  1. FSharp Vue SPA Start Guide/Template While it might not fit in with every situation having a functional language behind you backed, such as fsharp, could be very nice. This guide is not about setting up api handlers, but rather setting up giraffe routing to forward front end related things to the front end. To learn more about the HttpHandlers to go along with the api I would suggest reading up on the Giraffe documentation page. Microsoft has some ASP.NET Core SPA examples which I take some ideas from, but they have some extra stuff I don't wish to implement in this template such as JQuery and Bootstrap. Vue discourages the use of JQuery. I set out to create a good template that I can use later on and hopefully some other people can use it as a starting point. Technologies Used: Webpack Hot Module Replacement vue-loader Asp.net Core 2.0 Vue vue-router Prerequisites: dotnet core 2.x nodejs >= 8.9.4 VSCode or VS2017 If VSCode Ionide Fsharp extension Project Setup: Create a new folder with the name of your Project (FSharpVue in my case) Install Giraffe Template dotnet new -i "giraffe-template::*" Use the Giraffe Template to create some boiler plate code. dotnet new giraffe -lang F# Navigate into the project folder (src->FSharpVue) and remove WebRoot folder open Program.fs Remove the model and view bit of code under the last open. Change the web router to use our webpack index file. let webApp = choose [ GET >=> choose [ route "/" >=> htmlFile "wwwroot/dist/index.html" ] htmlFile "wwwroot/dist/index.html" ] This lets the front end handle any type of non static 404 Remove the custom WebRoot references (we will use default wwwroot) let main _ = let contentRoot = Directory.GetCurrentDirectory() WebHostBuilder() .UseKestrel() .UseContentRoot(contentRoot) .UseIISIntegration() .Configure(Action<IApplicationBuilder> configureApp) .ConfigureServices(configureServices) .ConfigureLogging(configureLogging) .Build() .Run() 0 Add Microsoft.AspNetCore.SpaServices via nuget or paket. open(import) Microsoft.AspNetCore.SpaServices.Webpack While the application is in development environment use Webpack dev middleware (match env.IsDevelopment() with | true -> app.UseWebpackDevMiddleware( WebpackDevMiddlewareOptions(HotModuleReplacement = true, ConfigFile = "build/webpack.dev.conf.js")) app.UseDeveloperExceptionPage() | false -> app.UseGiraffeErrorHandler errorHandler) This is where importing vue project gets dicey, I would argue it is not important to follow this point of the tutorial, but rather just look at how I did it in the attached template. For the most part forward we will just import vue and change a good bit of webpack config. I would not use the following as a guide to webpack, rather just a method of getting by. Though if you would like to follow along to get a better understand on the vue cli and webpack it might be helpful. TBH I don't know webpack the best and @Omicron had to help me out a bit with it. Install the vue-cli via npm npm install -g @vue/cli In the main project directory create a new vue project with webpack and name it clientapp (to match microsoft template convention) vue init webpack ? Project name clientapp ? Project description A Vue.js FSharp Template ? Author Smallxmac <[email protected]> ? Vue build standalone ? Install vue-router? Yes ? Use ESLint to lint your code? Yes ? Pick an ESLint preset Standard ? Set up unit tests No ? Setup e2e tests with Nightwatch? No ? Should we run `npm install` for you after the project has been created? (recommended) npm Now we have to heavily modify the mess that just got thrown into the directory. Rename src to ClientApp In webpack.base.config change src to ClientApp Remove dev server Remove the config in config/index.js under "//Various Dev Server settings" In package.json remove the dev and start script and you can remove the webpack-dev-server package. Remove the devServer section in build/webpack.dev.config.js replace module.exports with module.exports = devWebpackConfig; remove new webpack.HotModuleReplacementPlugin(), In config/index.js change all 'dist' to 'wwwroot' under dev change assetsPublicPath to /wwwroot At this point if you run npm run build it should emit the correct production files in the wwwroot folder. Add extra needed packages npm install cross-env -D npm install aspnet-webpack -D npm install webpack-hot-middleware -D Add script to package.json "dev": "cross-env ASPNETCORE_ENVIRONMENT=Development NODE_ENV=development dotnet run", That webpack sutff was a bit tedious to write so please just download the attached template and run it. Using Attached Template: unzip the template somewhere navigate to src/FSharpVue npm install or yarn install npm run dev How to build/run: DEVELOPMENT: npm run dev or dotnet run if you use dotnet run make sure your ASPNETCORE_ENVIROMENT is set to Development Production Build the wwwroot folder npm run build Run the aspnetcore project in production with dotnet run. Finial Thoughts: I have to be very clear with this. I would rather run backend api and frontend completely separate and not use kestrel to serve the ClientApp. I would like to make a better examples that uses a giraffe handler for some sort of API, but I figured that just setting up a template is enough for now. It is quite easy to add the api routing vs setting up this project in general. FSharpVue.zip
