Bolero hosting Razor page

mmgreiner@bluewin.ch (Markus Greiner) — Tue, 11 Apr 2023 00:00:00 +0000

In this post we investigate how to use Razor pages on the host and Bolero WebAssembly on the client side. The final code can be found on My github - Tutorials - BoleroAppRazor.

Miscellaneous

This is a list of reminders and open questions I still wanted to look at in more detail.

CSV conversion

Next to FSharp.Data there is CSVHelper. However, it does not support FSharp types intrinsically. A stackoverflow article describes the details.

RESTful API

This contains some thoughts how to implement RESTful APIs.

Some of my codes are documented on my Github with description in the readme files. Take a look there.

Github	Description
BoleroApp	A simple Bolero app with file upload and data repository using dependency injection
StringAlgorithms	Some string algorithms in F# to measure string similarity
WebAPI	A net7.0 based RestAPI in F#
DependencyInjection	simple attempts at dependency injection in F#
MinimalAPI	Minimal API with a file upload example
BoleroAppRazor	Bolero App, but using Razor pages on the server

Operation research

Usage of operation research in various programming languages for production optimization, scheduling, etc. problems.

PDF to text conversion

mmgreiner@bluewin.ch (Markus Greiner) — Thu, 01 Dec 2022 00:00:00 +0000

There is once in a while the need to extract pure text from PDF files. This blog shows some attempts to do it with dot, with ruby, and with command line utitilites.

Input file element with Bolero

mmgreiner@bluewin.ch (Markus Greiner) — Thu, 20 Oct 2022 00:00:00 +0000

Bolero is a set of free and open-source libraries and tools to write web applications in F#. With it, you can write fully dynamic client-side web applications from the comfort of a strongly-typed functional language, all with great performance.

Static templating with handlebars, liquid and others

This post describes how to use static temlating engines like handlebars, liquid, fluid etc when programming.

This blog contains some experiences working with Bolero.

Machine Learning with ML.NET

mmgreiner@bluewin.ch (Markus Greiner) — Fri, 08 Apr 2022 00:00:00 +0000

Machine learning with ML.NET is documented in a confusing way, in particular when it comes to F#.

Some resources I found are:

Mathe Uffzgi

Once in a while, I’m supporting Lea with her math homework (Swiss: Uffzgi). Here are some tools that help me (remember, that I prefer F# to other languages. Whenever possible, I use interactive Notebooks and make them available on github Notebooks.

WebSharper simple inputs

mmgreiner@bluewin.ch (Markus Greiner) — Thu, 17 Mar 2022 00:00:00 +0000

This post shows various ways to handle input using WebSharper.

Client side

There are two basic approaches: using HTML templates or using Websharper’s HTML.

WebSharper templates

mmgreiner@bluewin.ch (Markus Greiner) — Sun, 13 Mar 2022 13:00:00 +0000

WebSharper allows several ways to instatiate HTML, and It took me some thinking to get these terms right:

ws-replace
ws-hole
ws-template
ws-template-children

Replace

Replace the given node with the provided string or list of docs.

WebSharper shopping cart

mmgreiner@bluewin.ch (Markus Greiner) — Sun, 13 Mar 2022 10:41:39 +0000

Websharper Shopping cart

I found an interesting article from 2020 by Adam Granizc on the implementation of a WebSharper shopping cart in WebSharper Shopping Cart

Using Jekyll

mmgreiner@bluewin.ch (Markus Greiner) — Sat, 12 Mar 2022 19:00:00 +0000

You’ll find this post in your _posts directory. Go ahead and edit it and re-build the site to see your changes. You can rebuild the site in many different ways, but the most common way is to run jekyll serve, which launches a web server and auto-regenerates your site when a file is updated.
