+# FaceAPI
+
+## Note
+
+This is updated **face-api.js** with latest available TensorFlow/JS as the original face-api.js is not compatible with **tfjs 2.0+**.  
+
+Forked from **face-api.js** version **0.22.2** released on March 22nd, 2020  
+
+- <https://github.com/justadudewhohacks/face-api.js>  
+- <https://www.npmjs.com/package/face-api.js>  
+
+Currently based on **`TensorFlow/JS` 2.7.0**  
+If you want to access `TFJS` classes and methods directly, they are exported as `faceapi.tf`
+
+### Why?
+
+Because I needed FaceAPI that does not cause version conflict with newer TFJS 2.0 that I use accross my projects  
+And since original FaceAPI was open-source, I've released this version as well  
+Unfortunately, changes ended up being too large for a simple pull request on original FaceaPI and it ended up being a full-fledged version on its own  
+
+### Differences
+
+- Compatible with `TensorFlow/JS 2.0+`  
+- Compatible with `WebGL`, `CPU` and `WASM` TFJS backends
+- Updated all type castings for TypeScript type checking to `TypeScript 4.1`  
+- Switched bundling from `UMD` to `ESM` + `CommonJS`  
+  This does require separate process for usage in NodeJS vs Browser, but resulting code is much lighter  
+  Fully tree shakable when imported as an `ESM` module  
+  Browser bundle process uses `ESBuild` instead of `Rollup`  
+- Typescript build process now targets `ES2018` and instead of dual ES5/ES6  
+  Resulting code is clean ES2018 JavaScript without polyfills  
+- Removed old tests, docs, examples  
+- Removed old package dependencies (`karma`, `jasmine`, `babel`, etc.)  
+- Updated all package dependencies  
+- Updated TensorFlow/JS dependencies since backends were removed from `@tensorflow/tfjs-core`  
+- Updated mobileNetv1 model due to `batchNorm()` dependency  
+- Added `version` class that returns JSON object with version of FaceAPI as well as linked TFJS  
+- Removed `mtcnn` and `tinyYolov2` models as they were non-functional in latest public version of `Face-API`  
+  *If there is a demand, I can re-implement them back.*  
+
+Which means valid models are **tinyFaceDetector** and **mobileNetv1**  
+
+## Installation
+
+Face-API ships with several pre-build versions of the library:
+- `dist/face-api.js`: IIFE format for client-side Browser execution *with* TFJS pre-bundled
+- `dist/face-api.esm.js`: ESM format for client-side Browser execution *with* TFJS pre-bundled
+- `dist/face-api.esm.nobundle.js`: ESM format for client-side Browser execution *without* TFJS pre-bundled
+- `dist/face-api.node.js`: CommonJS format for server-side NodeJS execution *without* TFJS pre-bundled
+
+Defaults are:
+```json
+{
+  "main": "dist/face-api.cjs",
+  "module": "dist/face-api.esm.js",
+  "browser": "dist/face-api.esm.js",
+}
+```
+
+Reason for additional `nobundle` version is if you want to include a specific version of TFJS and not rely on pre-packaged one  
+`FaceAPI` is compatible with TFJS 2.0+  
+
+Bundled versions are ~1.1MB minified and non-bundled versions are ~169KB non-minified  
+All versions include `sourcemap`
+
+There are several ways to use Face-API: 
+
+### 1. IIFE script
+
+*Recommened for quick tests and backward compatibility with older Browsers that do not support ESM such as IE*
+
+This is simplest way for usage within Browser  
+Simply download `dist/face-api.js`, include it in your `HTML` file & it's ready to use
+
+```html
+<script src="dist/face-api.js"><script>
+``` 
+
+IIFE script bundles TFJS and auto-registers global namespace `faceapi` within Window object which can be accessed directly from a `<script>` tag or from your JS file.  
+
+### 2. ESM module
+
+*Recommended for usage within Browser*
+
+#### 2.1. Direct Import
+
+To use ESM import directly in a Browser, you must import your script (e.g. `index.js`) with a `type="module"`  
+
+```html
+  <script src="./index.js" type="module">
+```
+and then in your `index.js`
+
+```js
+  import * as faceapi from 'dist/face-api.esm.js';
+```
+or to use non-bundled version:
+```js
+  import * as tf from `https://cdnjs.cloudflare.com/ajax/libs/tensorflow/2.7.0/tf.es2017.min.js`; // load tfjs directly from CDN link
+  import * as faceapi from 'dist/face-api.nobundle.js';
+```
+
+#### 2.2. With Bundler
+
+Same as above, but expectation is that you've installed `@vladmandic/faceapi` package  
+and that you'll package your script using a bundler such as `webpack`, `rollup` or `esbuild`  
+in which case, you do not need to import a script as module - that depends on your bundler configuration  
+
+```js
+  import * as faceapi from '@vladmandic/face-api';
+```
+or if your bundler doesn't recognize `recommended` type, force usage with:
+```js
+  import * as faceapi from '@vladmandic/face-api/dist/face-api.esm.js';
+```
+or to use non-bundled version
+```js
+  import * as tf from `@tensorflow/tfjs`;
+  import * as faceapi from '@vladmandic/face-api/dist/face-api.nobundle.js';
+```
+
+### 3. NPM module
+
+#### 3.1. Import CommonJS
+
+*Recommended for NodeJS projects*
+
+*Node: Face-API for NodeJS does not bundle TFJS due to binary dependencies that are installed during TFJS installation*
+
+Install with:
+```shell
+  npm install @tensorflow/tfjs-node
+  npm install @vladmandic/face-api 
+```
+And then use with:
+```js
+  const tf = require('@tensorflow/tfjs-node')
+  const faceapi = require('@vladmandic/face-api');
+```
+- if you want to CUDA GPU Accelerated NodeJS, import `tfjs-node-gpu` instead of `tfjs-node`  
+  This requires that system is CUDA enabled and has CUDA libraries already installed.
+- If you want to force CommonJS module instead of relying on `recommended` field:
+```js
+  const faceapi = require('@vladmandic/face-api/dist/face-api.node.js');
+```
+
+### 4. Import Sources
+
+*Recommended for complex NodeJS projects that use TFJS for other purposes and not just FaceaPI*
+
+This way you're importing FaceAPI sources directly and not a bundle, so you have to import `@tensorflow/tfjs` explicitly  
+
+#### 4.1. For Browser with Bundler
+
+##### 4.1.1. For JavaScript projects
+```js
+  import * as tf from '@tensorflow/tfjs';
+  import * as faceapi from '@vladmandic/face-api/build/index.js';
+```
+
+##### 4.1.2. For TypeScript projects
+```js
+  import * as tf from '@tensorflow/tfjs';
+  import * as faceapi from '@vladmandic/face-api/src/index.ts';
+```
+
+#### 4.2. For NodeJS
+
+##### 4.2.1. For JavaScript projects
+```js
+  const tf = require('@tensorflow/tfjs');
+  const faceapi = require('@vladmandic/face-api/build/index.js');
+```
+
+##### 4.1.2. For TypeScript projects
+```js
+  const tf = require('@tensorflow/tfjs');
+  const faceapi = require('@vladmandic/face-api/src/index.ts');
+```
+
+## Weights
+
+Pretrained models and their weights are includes in `./model`.
+
+## Build
+
+If you want to do a full rebuild, either download npm module
+```shell
+npm install @vladmandic/face-api
+cd node_modules/@vladmandic/face-api
+```
+
+or clone a git project
+```shell
+git clone https://github.com/vladmandic/face-api
+cd face-api
+```
+
+Then install all dependencies and run rebuild:
+```shell
+npm install
+npm run build
+```
+
+Which will compile everything in `./src` into `./build` and create both ESM (standard) and IIFE (minified) bundles as well as sourcemaps in `./dist`

+
+### NodeJS
+
