Introducing Enhanced Alert Actions and Triage Functionality
Socket now supports four distinct alert actions instead of the previous two, and alert triaging allows users to override the actions taken for all individual alerts.

Readme
Tesseract.js is a javascript library that gets words in almost any language out of images. (Demo)
Image Recognition
Video Real-time Recognition
Tesseract.js wraps a webassembly port of the Tesseract OCR Engine. It works in the browser using webpack or plain script tags with a CDN and on the server with Node.js. After you install it, using it is as simple as:
import Tesseract from 'tesseract.js';
Tesseract.recognize(
'https://tesseract.projectnaptha.com/img/eng_bw.png',
'eng',
{ logger: m => console.log(m) }
).then(({ data: { text } }) => {
console.log(text);
})
Or using workers (recommended for production use):
import { createWorker } from 'tesseract.js';
const worker = await createWorker({
logger: m => console.log(m)
});
(async () => {
await worker.loadLanguage('eng');
await worker.initialize('eng');
const { data: { text } } = await worker.recognize('https://tesseract.projectnaptha.com/img/eng_bw.png');
console.log(text);
await worker.terminate();
})();
For a basic overview of the functions, including the pros/cons of different approaches, see the intro. Check out the docs for a full explanation of the API.
Version 4 includes many new features and bug fixes--see this issue for a full list. Several highlights are below.

Check the support/1.x branch for version 1
Tesseract.js works with a <script>
tag via local copy or CDN, with webpack via npm
and on Node.js with npm/yarn
.
<!-- v4 -->
<script src='https://cdn.jsdelivr.net/npm/tesseract.js@4/dist/tesseract.min.js'></script>
After including the script the Tesseract
variable will be globally available.
Requires Node.js v14 or higher
# For latest version
npm install tesseract.js
yarn add tesseract.js
# For old versions
npm install tesseract.js@3.0.3
yarn add tesseract.js@3.0.3
The following are old examples that use depreciated versions of Tesseract.js. Updating to Tesseract.js v4 is highly recommended. Users are encouraged to create updated examples (or make entirely new ones) and submit them as pull requests.
React Native is not supported as it does not support Webassembly.
To run a development copy of Tesseract.js do the following:
# First we clone the repository
git clone https://github.com/naptha/tesseract.js.git
cd tesseract.js
# Then we install the dependencies
npm install
# And finally we start the development server
npm start
The development server will be available at http://localhost:3000/examples/browser/demo.html in your favorite browser.
It will automatically rebuild tesseract.dev.js
and worker.dev.js
when you change files in the src folder.
You can use Gitpod(A free online VS Code like IDE) for contributing. With a single click it will launch a ready to code workspace with the build & start scripts already in process and within a few seconds it will spin up the dev server so that you can start contributing straight away without wasting any time.
To build the compiled static files just execute the following:
npm run build
This will output the files into the dist
directory.
