### Description This PR re-arranges documentation of ORT web. Current doc: https://onnxruntime.ai/docs/ Change preview: https://fs-eire.github.io/onnxruntime/docs/ - split `Doc -> Get Started -> JavaScript` from single page into multiple pages, to make it easier to split from web, node and react-native - remove `Doc -> Get Started -> with Web`. The page was a few links and now they are moved to other places - add a few contents into `Doc -> Get Started -> JavaScript -> Web`. Now this is the main page for ORT web doc. - rename `Tutorials -> deploy on Web` to `Tutorials -> Web`. "deploy" is confusing as it's not the accurate term to describe the content. ================================================================= ### Discussions: TBD ================================================================= ### ORT web documentation work item list: - [ ] Update `Get Started` page for ORT web at onnxruntime.ai **( this PR )** - to make it easier for users to navigate - [ ] Update `Tutorials` page for ORT web at onnxruntime.ai - The purpose of this page is unclear. It contains descriptive information and step-by-step instructions on an E2E examples. It can be a good Blog, but not good for documentation, which usually has a well-structured content. - The [index page](https://fs-eire.github.io/onnxruntime/docs/tutorials/web/) has duplicated contents with its child page ["Build a web application with ONNX Runtime"](https://fs-eire.github.io/onnxruntime/docs/tutorials/web/build-web-app.html) - Some contents are out-of-dated. - [ ] Update [`API Usage - SessionOptions`](https://github.com/microsoft/onnxruntime-inference-examples/tree/main/js/api-usage_session-options) on onnxruntime-inference-examples repo. - Add explaination and examples if necessary for all new WebGPU session options. - [ ] Update [`API usage - ort.env flags`](https://github.com/microsoft/onnxruntime-inference-examples/blob/main/js/api-usage_ort-env-flags) on onnxruntime-inference-examples repo. - Add all newly introduced flags.

## Install
|
|
|
|
Use the following command in shell to install ONNX Runtime Web:
|
|
|
|
```bash
|
|
# install latest release version
|
|
npm install onnxruntime-web
|
|
|
|
# install nightly build dev version
|
|
npm install onnxruntime-web@dev
|
|
```
|
|
|
|
## Import
|
|
|
|
Use the following JavaScript code to import ONNX Runtime Web:
|
|
|
|
```js
|
|
// use ES6 style import syntax (recommended)
|
|
import * as ort from 'onnxruntime-web';
|
|
```
|
|
```js
|
|
// or use CommonJS style import syntax
|
|
const ort = require('onnxruntime-web');
|
|
```
|
|
|
|
If you want to use ONNX Runtime Web with WebGPU support (experimental feature), you need to import as below:
|
|
|
|
```js
|
|
// use ES6 style import syntax (recommended)
|
|
import * as ort from 'onnxruntime-web/webgpu';
|
|
```
|
|
```js
|
|
// or use CommonJS style import syntax
|
|
const ort = require('onnxruntime-web/webgpu');
|
|
```
|
|
|
|
