Installation

There is a hard dependency on the Tesseract project. You can find installation instructions for various platforms on the project site. For Homebrew users, the installation is quick and easy.

brew install tesseract --with-all-languages

The above will install all of the language packages available, if you don't need them all you can remove the --all-languages flag and install them manually, by downloading them to your local machine and then exposing the TESSDATA_PREFIX variable into your path:

export TESSDATA_PREFIX=~/Downloads/

You can then go about installing the Node.js package to expose the JavaScript API:

npm install tesseractocr
