How to resolve domain to IP address for Collabora Office server with dynamic IP for nextcloud office

Problem

If you install your own Collabora Office server on your home server and your public IP address changes from time to time (dynamic IP address) you'll find an issue: Your nextcloud ist blocking requests to the office server because the IP of the wopi allow list does not match that one from your server. For now you are not able to set a domain to the wopi allow list directly in nextcloud settings.

Solution

A PHP script resolves the domain of your Collabora Office server to an IP address and sets the new IP address to the wopi allowlist of your nextcloud instance. Simple! :)

How to hash files while uploading using multer and typescript

How to allow leading underscores in tslint.config

Add the following rule at the end of your tslint.config. If it does already exist, change it :)

"variable-name": [
true,
"allow-leading-underscore"
]

Why?

Easy web worker with Typescript

This code makes use of two classes: TsWorker and TsWorkerJob. TsWorker initializes an inline worker and runs one job. The TsWorker class needs to be initialized with a function and the function's arguments as an array.

Example:

 const tsWorker = new TsWorker();

 // create a new job. You can create a sub class of TsWorker so that you don't have to add the function any time.

New generator

I created a new htaccess generator for angular apps that makes it easier for you to create the optimal htaccess file: https://julianpoemp.github.io/ngx-htaccess-generator/

The goal of this generator is to create the optimal .htaccess file for Angular apps easily. By default the generator creates an .htaccess file that solves the route redirection issue. To make it easier for you I created a kind of interview mode with some questions. As an additional feature the generator supports adding exclusions for example if you have installed a blog in a subdirectory of your web application and more!
