Managing Files

Stores allow you to exchange and save files. In this section, we'll take a closer look at file structures and how to manage them effectively. We'll also cover some best practices when working with Stores.

About Files

Along with a file's main content, additional metadata is stored to allow easy file management. Below is the structure of the metadata associated with each file:

field	type	encrypted	description
info	ServerFileInfo	yes	additional information assigned by the server e.g. author, creationDate, storeID and fileID
publicMeta	binary	no	additional public information about the message, also accessible through Platform REST API
privateMeta	binary	yes	additional information about the message
size	number	yes	The size of file in getBytes
authorPubKey	string	yes	The public key of the author of the file
statusCode	number	no	0 if the file was decrypted successfully

Listing files

Here's how you can retrieve and list files from a Store:

const files = await Endpoint.connection().store('STORE_ID').getFiles(0, {
    sort: 'desc',
    pageSize: 100
});

const decoder = new TextDecoder();
files.readItems.forEach((file) => {
    const privateMeta = decoder.decode(file.privateMeta);
    const publicMeta = decoder.decode(file.publicMeta);

    return {
        ...file,
        publicMeta,
        privateMeta
    };
});

Deleting Files

Deleting a file is straightforward, but be aware that this action is irreversible:

await Endpoint.connection().stores.deleteFile("FILE_ID");
