Kontaktlinsen nicht in die Toilette

Wer kennt es nicht? Nach einem langen Tag stehst Du im Bad, Zähneputzen und zum Schluß die Tageslinsen raus. Diese kleinen praktischen Dinger, die durch ihre Weichheit so gut verträglich sind. Dank Internet und Preisvergleich ist das auch nicht mehr teuer. Das lästige Reinigen der Linsen entfällt ja auch, weil du sie einfach wegschmeißt und morgen früh eine Frische neue aus der Packung nimmst. Wirklich praktisch!

UPDATE: I added a section on how to renew the certificate.

You will see how to set up a Firebase project which uses hosting and cloud functions written in Typescript. We add a VueJS project that will build our website and is hosted with Firebase hosting. After we set up these two parts, we are going to adjust some scripts to create a smooth development cycle with hot-reloading everywhere.
