Show HN: Srcbook – A TypeScript notebook for rapid prototyping

Srcbook is an open-source notebook application designed for TypeScript and JavaScript, enabling users to create, run, and share reproducible programs and ideas. It incorporates AI features for idea exploration and offers a local execution environment with a web interface. The application is licensed under the Apache 2.0 license. Key features include the ability to export to valid markdown format, local execution powered by Node.js, and an interactive programming environment specifically for TypeScript. To get started, users need Node.js version 20 or higher, and installation can be done via npm. The application can be run using the command `srcbook start`, or alternatively with `npx`. Users can also import Srcbooks and access help commands. For maintenance, the application can be updated or uninstalled using npm commands. Srcbook collects behavioral analytics to enhance user experience but ensures that no personal or identifiable information is gathered, with an option to disable tracking in the settings. For further guidance, users are encouraged to consult the CONTRIBUTING.md file in the repository.

Nice, if you could run wasm inline, one could conceivably use it for rust debugging or typst like this: https://github.com/Myriad-Dreamin/typst.ts

Also see this jupyter notebook request https://github.com/typst/typst/issues/962

I think this really nails a missing sweet spot for frontend/node projects.

Observable is a great notebook env for dataviz, but the bespoke js + observability patterns can feel obtuse for non-dataviz stuff.

Likewise, the Jupyter js kernels feel second-class and require python dependencies.

Really looking forward to using this for documenting open-source and prototyping.

Really awesome to see this stuff continued to be worked on. I had a small project I worked on almost a decade ago https://github.com/gabrielcsapo/node-notebook, things have gotten so much better.

To those concerned about the analytics like myself, you should be able to turn it off by setting the default here to false. Otherwise you'd need to toggle it off in the settings, which gives ample time for telemetry to fire.

Love that this is local. I've messed around trying to get Node on Jupyter with custom kernels, but never got close to a working setup with TypeScript.

Two features would be huge:

1. Web cells for intermixing UI components alongside NodeJS cells. Would be cool if there was a bridge API to call code in the Node cells as well.

2. VSCode extension to render this all in there directly.

Does this include, or are there plans for MDX/React component support? That would be amazing and I would use it extensively.

How does it compare with Observable? https://observablehq.com/

This is a cool idea! I often end up just using replit to play with a library, something more like Livebook makes a lot of sense. I like that you're using markdown too, makes these files much more useful than Jupyter ones.

Very nice. I am trying using ollama with it, looks like something is off either on my server or in the way the program calls it: I get the CPU used instead of the GPU (while using ollama in other apps doesn't).

Anyway, impressive

Very cool! I wish there was also a "browser" cell, so that the execution wouldn’t be happening in the node.

The examples are complete programs.

Can I let-declare an variable in one code block, and refer to it in another code block with static type hint?

This looks interesting. What are some of the coolest srcbooks you have seen so far?

I’ve always wanted a TypeScript-based Jupyter notebook, thanks for building this!
By @ashobeiri - 6 months
This is really cool, looking forward to trying it out. Love the name as well
By @h1fra - 6 months
Very nice, how do you run the code? is it securely sandboxed?
By @fkilaiwi - 6 months
this is awesome. how do you plan to monetize this?
By @bityard - 6 months
Jupyter can run JS kernels these days.

I hate to be negative, but I'm not entirely sure why this is advantageous over just dumping a bunch of HTML files into a folder. Why can't the code live in <script type="module">'s with `display: block` tagged, using esm.sh for libraries? Why do we have to use Markdown that has to get transpiled over a format that can be natively consumed by the browser?
