Our web application includes a front-end, and a Laravel back-end, and uses GraphQL and REST APIs. It also utilizes microservices, an SQLite database, indexedDB, cache API, and Service Workers. We built it with TypeScript and styled it with Tailwind CSS, and Google Sheets APIOur web application has two main components: a front-end and a Laravel back-end. It uses both GraphQL and REST APIs and relies on microservices architecture. We store data in an SQLite database, use indexedDB and cache API for faster performance, and implement Service Workers for offline support. We wrote the code in TypeScript and styled the app with Tailwind CSS and the Google Sheets API. HTTP requests, message queues, databases, enterprise service bus (ESB), webhooks, integration layer, and JSON are

...server/backend relational database (PostgreSQL). From our understanding, we have had ideas like listed below, but feel free to propose any better, alternative solution of your choice. - Using FDW - Foreign Data Wrapper for PostgreSQL - for indexedDB. - Use e.g. RxDB with an adapter for PostgreSQL. - Manually build a solution that trigger on database updates and send a copy of such transaction to web clients that are known in a list. (The preferred choice of Postgres is because of that Postgres have triggers on views.) Maybe over websocket and update IndexedDB and/or only update a variable containing the objects corresponding to the rows in the view. Updates in the client could be handled the opposite way, or that the clients writes directly to the server database. This syn...

We have a web-based application which works in offline mode (PWA). The requirement is to add a feature to render an Invoice HTML from data stored in the local IndexedDB. The HTML format and database is all frozen. You don't have to do any modifications to the database. Just access the local DB and generate the HTML using JavaScript/JQuery. There are 5 different such HTMLs to be generated. All are typically 1 page in size.
