Connect is a family of libraries for building and consuming APIs on different languages and platforms. [@connectrpc/connect](https://www.npmjs.com/package/@connectrpc/connect) brings type-safe APIs with Protobuf to TypeScript.

React hook for using error boundaries

split {japanese, english} text into sentences.

Join all elements of an array and create a human-readable string

textlint rule check sentence length

Extracts the boundary of a simplicial complex

Enumerates all boundary cells in a simplicial complex

Convert a string to sentence case.

<!-- BADGES -->

retext plugin to check spacing (one or two spaces) between sentences

Escape carriage return the right way.

worker-thread workflow engine: executes model-written orchestration scripts off the host event loop, bridging agent() calls back to ctx.subagents

A React error boundary hook for function components

Split a English sentence without any spaces nor accents, into words.

Sandbox-enforcing implementation of the DeepSeek Harness filesystem seam: fences write/edit by the per-call sandbox mode (read-only denies mutation, workspace-write contains it to the workspace + temp roots) while reads pass through

Algorithm to calculate optimal cell boundaries between multiple boxes

Simple error creation, boundaries, and formatting utilities

A javascript/nodejs multipart/form-data parser which operates on raw data.

The engine that powers scroll-into-view-if-needed
