# VSCode Webview React

This project was bootstrapped with
* [Create React App](https://github.com/facebookincubator/create-react-app)
* [Create React App TypeScript](https://github.com/wmonk/create-react-app-typescript)
* [VSCode Extension Webview Sample](https://github.com/Microsoft/vscode-extension-samples/tree/master/webview-sample)

[The webview API](https://code.visualstudio.com/docs/extensions/webview) allows extensions to create customizable views within VSCode. Single Page Application frameworks are perfect fit for this use case. However, to make modern JavaScript frameworks/toolchains appeal to VSCode webview API's [security best practices](https://code.visualstudio.com/docs/extensions/webview#_security) requires some knowledge of both the bundling framework you are using and how VSCode secures webview. This project aims to provide an out-of-box starter kit for Create React App and TypeScript in VSCode's webview.

## Development

Run following commands in the terminal

```shell
yarn install --ignore-engines
yarn run build
```
And then press F5, in Extension Development Host session, run `Start React Webview` command from command palette.

## Under the hood

Things we did on top of Create React App TypeScript template

* We inline `index.html` content in `ext-src/extension.ts` when creating the webview
* We set strict security policy for accessing resources in the webview.
* Only resources in `/build` can be accessed
* Onlu resources whose scheme is `vscode-resource` can be accessed.
* For all resources we are going to use in the webview, we change their schemes to `vscode-resource`
* Since we only allow local resources, absolute path for styles/images (e.g., `/static/media/logo.svg`) will not work. We add a `.env` file which sets `PUBLIC_URL` to `./` and after bundling, resource urls will be relative.
* We add baseUrl `` and then all relative paths work.

## Limitations

Right now you can only run production bits (`yarn run build`) in the webview, how to make dev bits work (webpack dev server) is still unknown yet. Suggestions and PRs welcome !
