How to Use an Updated Access Token in Content Explorer

Hello, I am using the non-React version of Content Explorer, as documented here: https://developer.box.com/docs/box-content-explorer#section-sample-html.

 

Everything is working great. As expected, the access token expires after about 60 minutes. I have a separate service that is able to get a new access token in the background. However, I cannot figure out how to update the Content Explorer instance with this new token.  Calling contentExplorer.show() with the new token doesn't seem to work. I feel like I'm missing something super obvious. Thanks.

     how are you updating the access token? Have you tried explicitly removing the container and then reinitialize the explorer?

     thanks for the suggestion.  Removing the container and reinitializing the explorer works, but it's undesirable for 2 reasons:

    • there is a visual flicker 
    • the navigation hierarchy is reset to the top level

    Is there really no way to update the token in place? This must be a common scenario, no? I'm browsing some files, I step away for lunch, I come back, bam - I get an error when I try to resume browsing.

     

    I did find these issues (#640, #641), which ask the same question for Content Preview. I don't quite understand the final comment: "We decided to keep the interface for box-content-preview and make modifications to the interface at a higher level in box-ui-elements." It's referring to an undocumented updateToken method on Content Preview.

    Hi :

     

    The token value is passed to our API factory when ContentExplorer is instantiated; we currently don't provide a mechanism to update it afterward. However, rather than passing a token string, you could instead pass a function that returns a promise that resolves to a token string:

    const contentExplorer = new ContentExplorer();
const tokenGenerator = function() {
    // Whatever logic is needed, so long as it returns a promise which ultimately resolves with a token string
};

contentExplorer.show(FOLDER_ID, tokenGenerator);

    You can find related documentation for the same concept in our box-content-preview library. Hope that helps.
