tscircuit

Make electronics using Typescript, React, and AI tools.

Definitions for the tscircuit intermediary JSON format

An MIT-licensed full-pipeline PCB autorouter library for node.js and TypeScript projects. Part of [tscircuit](https://github.com/tscircuit/tscircuit)

The core logic used to build Circuit JSON from tscircuit React elements.

Write Winter-CG compatible routes with filesystem routing and tons of features

The goal of this module is to find the best schematic layout for a set of `SchematicChip`s and `SchematicGroups` containing `SchematicPins` connected to each other with `SchematicTraces`

Props for tscircuit builtin component types

Evaluate code in a full tscircuit runtime environment, including Sucrase transpilation and execution, so you just need to send the code to be executed with automatic handling of imports from `@tsci/*`

Render GLTF files to PNG images in completely native JavaScript without WebGL/OpenGL.

An automatic layout system for schematics that uses the **PMARS** pattern:

TypeScript-first parser and serializer for Altium document formats

A box pin color (BPC) graph is a specialized graph structure where:

Utility library for working with tscircuit circuit json

A generic A* pathfinding solver for routing connections through hypergraphs. Designed for circuit routing problems but extensible to any graph-based pathfinding scenario.

A tscircuit-compatible SPICE engine using ngspice.

This is an internal module, you probably want [tscircuit](https://github.com/tscircuit/tscircuit)

Run [SPICE](https://en.wikipedia.org/wiki/SPICE) simulations in native javascript. An alternative to [ngspice](https://ngspice.sourceforge.io/)

Generate test plans for parallel CI execution with bun test

A TypeScript library that computes "elbow" paths between two points. Each point can optionally declare a facing direction—`"x+"`, `"x-"`, `"y+"`, or `"y-"`—which influences how the path enters or exits the point. This is handy when routing wires or connec

Convert Circuit JSON into a Box-Pin-Color Graph

To install dependencies:

Generate a cache key(s) to enable re-using previous autorouting results.

Cable definition DSL and schemas for tscircuit assemblies

Convert circuit-json designs into 3D PNG renders.

A utility to convert Circuit JSON to Bill of Materials (BOM) CSV format.

Convert Circuit JSON into a Pick'n'Place CSV

Generate FDM enclosure geometry from board dimensions and wall apertures

A shim for common image comparison/manipulation libraries. Created because we wanted to avoid issues with `sharp` and `WASM` bundles. Implements "transparent API" where you can drop in `"@tscircuit/image-utils/sharp"` where you use `"sharp"`
