tesseract.js

Tesseract.js is a pure javascript version of the Tesseract OCR Engine that can recognize English, Chinese, Russian, and 60 other languages.

Installation

Tesseract.js works with a <script> tag via local copy or cdn, or with npm (if you're using webpack / browserify).

Script Tag

CDN

<script src='https://cdn.rawgit.com/naptha/tesseract.js/5ed4c0bc/dist/tesseract.js'></script>

<script>
var worker = createTesseractWorker('https://cdn.rawgit.com/naptha/tesseract.js/5ed4c0bc/dist/tesseract.worker.js')

worker.recognize('#my-image')
    .progress(function (p) { console.log('progress', p) })
    .then(function (result) { console.log('result', result) })
</script>

Local

First grab copies of tesseract.js and tesseract.worker.js from the dist folder. Then include tesseract.js on your page like this:

<script src='/path/to/tesseract.js'></script>

<script>
var worker = createTesseractWorker('/path/to/tesseract.worker.js')

worker.recognize('#my-image')
    .progress(function (p) { console.log('progress', p) })
    .then(function (result) { console.log('result', result) })
</script>

Contributing

Development

To run a development copy of tesseract.js, first clone this repo.

> git clone https://github.com/naptha/tesseract.js.git

Then, cd in to the folder, npm install, and npm start

> cd tesseract.js
> npm install && npm start

  ... a bunch of npm stuff ... 

  tesseract.js@1.0.0 start /Users/guillermo/Desktop/code_static/tesseract.js
  node devServer.js

Listening at http://localhost:7355

Then open http://localhost:7355 in your favorite browser. The devServer automatically rebuilds tesseract.js and tesseract.worker.js when you change files in the src folder.

Building Static Files

After you've cloned the repo and run npm install as described in the Development Section, you can build static library files in the dist folder with

> npm run build
