    The only missing thing is search at any position of a string. Something similar to the 'LIKE' SQL operator. If anyone has a solution for this please give me a call.

    I am developing a language assistant as a PWA: https://www.marlems-assistent.de. I'm looking for a way that the speech recognition and speech output works on all operating systems. The website of the Google translator can do this: https://translate.google.com/?hl=de. Question: Is there a way to implement voice recognition and speech output in my PWA? Accessible greetings

    Thank you for the clear and presise video.

    Though..there is something I have been wondering about… Let's say that I have an object-store.service.ts file in Angular. In this object-store service I have multiple methods that can be used at different times win the application. I.e.:
    – InitializeStores
    – UpdateStores
    – DeleteStores
    – getStoreData
    Etc…
    One of the methods is even called manually by the user when the user clicks on the "Refresh application data" button.

    What is most common of these two?
    1) When your Angular app starts assign a global variable (IDBPDatabase type) the return/response from the openDB(…) call and the keep it in the memory until next time you need one or more of the object stores? Meaning: you only open the database once and then reuse the db global variable
    2) You use openDB(…) in the beginning of each of your methods that go against the database itself or the object stores

    The reason I am asking is that very many videos and examples I watch/see online contains just snippets on how to use the different methods like openDB, deleteDB, get(key), etc. as if they were just all by themselves. Few places I have seen anything about how you practically use idb within a real application…
