 1 | # VSCode Webview React
 2 | 
 3 | This project was bootstrapped with 
 4 | * [Create React App](https://github.com/facebookincubator/create-react-app)
 5 | * [Create React App TypeScript](https://github.com/wmonk/create-react-app-typescript)
 6 | * [VSCode Extension Webview Sample](https://github.com/Microsoft/vscode-extension-samples/tree/master/webview-sample)
 7 | 
 8 | [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.
 9 | 
10 | ## Development
11 | 
12 | Run following commands in the terminal
13 | 
14 | ```shell
15 | yarn install --ignore-engines
16 | yarn run build
17 | ```
18 | And then press F5, in Extension Development Host session, run `Start React Webview` command from command palette.
19 | 
20 | ## Under the hood
21 | 
22 | Things we did on top of Create React App TypeScript template
23 | 
24 | * We inline `index.html` content in `ext-src/extension.ts` when creating the webview
25 | * We set strict security policy for accessing resources in the webview.
26 |   * Only resources in `/build` can be accessed
27 |   * Onlu resources whose scheme is `vscode-resource` can be accessed.
28 | * For all resources we are going to use in the webview, we change their schemes to `vscode-resource`
29 | * 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.
30 | * We add baseUrl `<base href="${vscode.Uri.file(path.join(this._extensionPath, 'build')).with({ scheme: 'vscode-resource' })}/">` and then all relative paths work.
31 | 
32 | ## Limitations
33 | 
34 | 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 !
