OpenCV JavaScript version (NPM package) for node.js or browser. Get started guide OpenCV.js Tutorials.
The file opencv.js was downloaded from https://docs.opencv.org/4.9.0/opencv.js
TypeScript is supported (thanks to mirada).
npm install @techstark/opencv-jsyarn add @techstark/opencv-jsimport cv from "@techstark/opencv-js"
"esModuleInterop": true in tsconfig.jsonimport * as cv from "@techstark/opencv-js"If you use this package for browsers, you need to set some polyfills. In the file "webpack.config.js", set
module.exports = {
resolve: {
modules: [...],
fallback: {
fs: false,
path: false,
crypto: false
}
}
};
import cv from "@techstark/opencv-js";
Object.keys(cv).filter((key) => !key.includes("dynCall"));
