Microsoft File Browser SDK (Preview)

The Microsoft File Browser SDK provides a reusable React component for building file experiences with the Microsoft Graph. By using the SDK, any React application can render and perform actions on files by providing a valid access_token. In this guide, we will show you how to get your React app quickly rendering the File Browser component for Microsoft Graph.


1. Add Microsoft File Browser as a dependency

In order to use the SDK, you will need to add @microsoft/file-browser to your project as a dependency. Using NPM, you can add the dependency by running the following command:

$ npm i --save @microsoft/file-browser

2. Add SDK peer dependencies

The Microsoft File Browser SDK relies on several peer dependencies. The bundle requires its consumers to provide react and react-dom. If you are using TypeScript, the package also relies on typings for React and office-ui-fabric-react. The office-ui-fabric-react components themselves are included in the bundle.

Below is an example package.json excerpt showing the dependency on @microsoft/file-browser with appropriate peer dependencies that you should match in your project:

"dependencies": {
  "@microsoft/file-browser": "~1.0.0-preview.0",
  "office-ui-fabric-react": "^5.123.0",
  "react": "^16.5.2",
  "react-dom": "^16.5.2",
"devDependencies": {
  "@types/react": "^16.4.14",
  "@types/react-dom": "^16.0.7"

3. Render the File Browser

Once the required dependencies have been added to your React project, you are ready to render the GraphFileBrowser component. To successfully fetch and display files, the component expects a valid access_token be returned via the required getAuthenticationToken prop. Below is an example implementation:

class App extends React.Component {
  public render() {
    return (
        getAuthenticationToken={this.getAuthenticationToken} />

  private getAuthenticationToken() {
    return Promise.resolve('<access_token>');

In the above example, you will need to replace <access_token> with a valid access token for authentication. One way to quickly test a valid token is to sign-in to the Microsoft Graph Explorer. Once signed-in, you can copy the access token for your account from the access_token query parameter.

More information on acquiring valid authentication tokens for the Microsoft Graph can be found in this tutorial.
