New – Export Files to Zip Folders

Bethany StachenfeldProduct Updates1 Comment

Filestack has long been enabling developers to allow end users to directly upload multiple files from multiple cloud sources like Dropbox, Facebook, and Google Drive in a seamless experience.

The ability to save solitary files back to cloud sources or a user’s computer is a little known Filestack feature. Today we are proud to announce new functionality that will extend these capabilities.

For some time, Filestack has enabled users to save single files to desktop and cloud drives using the Export API, but today we are proud to announce a new feature:

Export to Zip

The Zip File Export feature is particularly exciting for two reasons:

  1. You can now compress large files into a zip file for super fast exports. Data transfer to the user starts immediately, as soon as the compression process starts. This means no timeouts, and your users never have to wait for the download to start.
  2. You can now bundle multiple files into one zip file, so if you are working with applications that traffic in multiple files per individual user (such as a resume, photograph, work sample, etc.), you can now export an entire user’s file library in one easy step by consolidating them into one zip archive that is easy to manage.

SeamlessDocs uses this functionality to export hundreds of files attached to an application into one folder for review. See SeamlessDocs’ case study here.

Try it for yourself!

The way the zip export works is simple. Similar to Filestack’s usual file transformations, the developer can simply run a “zip” conversion for a file handle or bundle of file handles in an array in order to generate a zip file.

Zip a Filestack Handle

The basic structure to compress multiple files using Filestack handles is below :

https://process.filestackapi.com/zip/[image 1 handle,image 2 handle,image 3 handle]

For example, to make a zip file that contains the following images:

    • Image 1: https://cdn.filestackcontent.com/u330JpHeShS8eK1wdYV0
    • Image 2: https://cdn.filestackcontent.com/XyiMHLohQnz7HJbLNkvn
    Image 3: https://cdn.filestackcontent.com/jnDfD8f7Tpq0BqCGwvS4

When you make a call to:

GET /zip/[files]
curl -g https://process.filestackapi.com/zip/[u330JpHeShS8eK1wdYV0,XyiMHLohQnz7HJbLNkvn,jnDfD8f7Tpq0BqCGwvS4]-X GET > file.zip

You are returned a compressed file that includes all files from the files array. Click below to see:

Or Use External Image URIs

You can compress multiple files from external sources using a similar structure, the difference is that you must specify your API key in the processing URI. For example:

GET //zip/external_source
curl - g https://process.filestackapi.com/AhTgLagciQByzXpFGRI0Az/zip/[https://www.wikipedia.org/portal/wikipedia.org/assets/img/Wikipedia-logo-v2@2x.png,https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png] -X GET > file.zip

And you are returned the compressed file.
