OpenCV4js

Description

This is the official OpenCV.js file packaged into a npm package for ease of use with no modifications in code whatsoever.

Please note that this package is not maintained by the OpenCV team/contributors.

Why OpenCV4js?

This package is updated whenever a new OpenCV version is released officially. By using the package in your OpenCV based Node.js project, you don't need to manually place the opencv.js file or worry about keeping it up to date later.

npm update will automatically fetch the updates, if any, just like any other package.

Also, the release numbers are synced with the official OpenCV releases for easy tracking. (Available v3.3.1+)

Installation

Install from command line

npm i --save opencv4js

Usage

With this package, you can skip placing the opencv.js file (as mentioned in the tutorials) and use the following code to import it:

cv = require('opencv4js');

instead of

cv = require('./opencv.js');

Or

replace

global.cv = require('./opencv.js');

with

global.cv = require('opencv4js');

Rest of the usage will be similar to the official docs and no other changes are required.
