API ReferenceJavaScript SDK`basehub` ClientmutationgetUploadSignedURL

getUploadSignedURL

A helper to upload assets to our database.

This is useful for example, when we have a PNG on our machine that we want to use in a BaseHub Image block. In order to use it, you should:

Call the getUploadSignedURL mutation1

You will need to retrieve both the signedURL and the uploadURL.

Do a PUT request to the signedURL2

The signedURL is an authorized endpoint that allows you to send any allowed asset through it. You’ll use it to upload the files you want to use in your BaseHub blocks.

Consume the uploaded data from uploadURL3

The uploadURL is the path to the uploaded file. After sending the asset data to the signedURL, you will be able to see the file in this URL. You will use it in the block value when running a transaction mutation.

Example

On this example we’re uploading a new image file to BaseHub assets pool.

You can explore the full code for this example in Github.

export const uploadImageToBaseHub = async (imageInput: File) => {
  const { getUploadSignedURL } = await basehub().mutation({
    getUploadSignedURL: {
      __args: {
        fileName: imageInput.name,
      },
      signedURL: true,
      uploadURL: true,
    },
  });

  const uploadStatus = await fetch(getUploadSignedURL.signedURL, {
    method: "PUT",
    body: imageInput,
    headers: {
      "Content-Type": imageInput.type,
    },
  });

  if (uploadStatus.ok) {
    return getUploadSignedURL.uploadURL;
  }

  return null;
};
