Web workers and service workers Similarities How web workers and service workers can improve the performance of your site, and when to use a web worker versus a service worker. What do you think it would take to do realtime collaboration with a shared session that spans multiple browser tabs? jupyterlab/rtc synchronizes with a y.js CRDT for the one notebook but not the whole IDE? Is that a common use case? While held, no other script executing in the same origin can acquire the same lock, which allows a web app running in multiple tabs or workers to coordinate work and the use of resources. The Web Locks API allows scripts running in one tab or worker to asynchronously acquire a lock, hold it while work is performed, then release it. This model eliminates the cold starts of the virtual machine model. Instead of creating a virtual machine for each function, an isolate is created within an existing environment. Isolates are also designed to start very quickly.

Each isolate's memory is completely isolated, so each piece of code is protected from other untrusted or user-written code on the runtime. The Broadcast Channel API allows communication between Tabs, Windows, Frames, Iframes, and Web Workers.Ī single runtime can run hundreds or thousands of isolates, seamlessly switching between them. "4 Ways to Communicate Across Browser Tabs in Realtime" workers can spawn workers, provided they are hosted within the same origin as the parent page). Note: Web Workers can also use the Web Worker API (i.e. The advantage of this is that laborious processing can be performed in a separate thread, allowing the main (usually the UI) thread to run without being blocked/slowed down. Web Workers makes it possible to run a script operation in a background thread separate from the main execution thread of a web application. AFAIU, web workers are possible without multiple browser tab overhead. JupyterLite implements the pyolite kernel in a Web Worker that doesn't block the main thread. could sync multiple tabs open to the same frontend to one or more kernels. The alternative is to have (1) per-tab overhead and (2) cross-tab synchronization overhead and (3?) copy-paste difficulty. It would be nice to not have to reinvent the wheel on that one. There's a real disadvantage to trying to implement tabs within a single browser tab: browsers do Many Clever Things to keep performance high by limiting action in non-visible tabs. Warning: this thought is pretty out there.
