fastText.wasm

WebAssembly version of fastText with compressed lid.176.ftz model (~900KB) and a typescript wrapper
This project focuses on cross-platform, zero-dependency and out-of-the-box

Compare

$3

fastText.js uses pre-built binaries, which theoretically has a higher performance ceiling, but only supports Node.js on most common systems and archs
Also, it is written in JavaScript and does not provide type definitions, so it is not easy to use for TypeScript projects

$3

languagedetect is a popular node language detection library, its size (~300KB) is smaller than fastText.wasm (~1.4MB)
But it's slower and less accuracy than fastText.wasm, and does not support some common languages like Chinese

Features

- [x] Out of the box
- [x] Written in TypeScript
