Using IndexedDB to Store Key Value Pairs with Vanilla JavaScript

#JavaScript #IndexedDB

Je continue à faire évoluer Imagilire Libre : l’application passe à IndexedDB avec Dexie pour un stockage local plus solide et plus fiable.
J’ai aussi ajouté l’export/import des paramètres et du dictionnaire syllabique personnalisé.
🔒 Les données restent stockées localement sur l’appareil. Aucune n’est transmise aux serveurs Imagilire.

Hi everyone, anyone knows reliable resources on building offline-first web apps with database offline synchronization? I need to do that for my job but terribly stuck.

Learning about IndexedDB today, hoping it can help with search performance in my bookmark manager app. High hopes!

An #E2EE messaging app unaffected by #ChatControl

* App: https://chat.positive-intentions.com/
* Code: https://github.com/positive-intentions/chat
* Reddit: https://www.reddit.com/r/positive_intentions

How it works: https://positive-intentions.com/docs/projects/chat

TLDR: I'm working on a #P2P messaging #webapp. Webapps are generally not considered secure because of the nature of serving statics over the internet. This is correct, but not a limitation of this project. (#selfhosting options: https://positive-intentions.com/blog/docker-ios-android-desktop).

As a webapp, I can provide the app with zero-installation and no-registration. The app is only using (local-only) browser storage (specifically #indexedDB). So in a P2P interaction, the traditional concept of "the cloud" is just the physical devices connected over #WebRTC. This allows for things like P2P authentication: https://positive-intentions.com/blog/security-privacy-authentication.

Future:
I'm aiming to create the most secure messaging app out there... (more than #Signal, #Simplex, #threema, #session, #deltachat, #bitchat, etc). I know I have a long way to go to get there. The UI is fairly ugly for the average user, but I think the mechanics are working as expected. I think #JavaScript is underrated in what you can do with it. I'm actively investigating improving the #encryption approach further to align to how the Signal protocol works (currently using a #DiffieHellman key-exchange).

Support:
In the age of #ChatControl, I would like to keep this project #opensource, but open-source funding is not working for me. I don't want your donations (but don't let that stop you) because it isn't sustainable for a long-term project. I have so far only experienced grant-funding rejections. I have no idea what I'm doing in trying to get funding for this project, so any support/advice is appreciated. In recognition of the project in its current state not being able to get funding... (sorry) I will have to go #closedsource (which I'd like to avoid because it undermines several #cybersecurity claims I'd like to make). I don't accept collaboration on the project because this would make tough decisions like going closed-source also immoral.

After building a paginated list of items using Dexie’s liveQuery feature, I’ve now refactored the project to use static queries instead.

The live updates aren’t worth the hassle and inconsistencies you have to deal with when using liveQueries—although I’d love for a future version of Dexie to make this easier (which it seems there are plans for in v5 🤞).
