# Searchable brand asset library for your Amazon S3 files

> Give your marketing team a visual, searchable library of the brand files already sitting in Amazon S3, with tags, approvals and one-click sharing to Slack.

## What it does

- Turns any bucket and folder into a searchable grid of your brand files, with a preview image, file type, size and last updated date on every card.
- Filters by file type, folder and tag, so anyone can jump straight to the spring launch artwork or see only the files marked approved.
- Opens any asset in a detail panel with a larger preview, its full details, a download button, and tag editing to mark files approved or retired.
- Lets your team upload new files into the right folder and share a selection to a Slack channel with names and a short description.

## What you'll need

- An Amazon S3 account, plus the name of the bucket and folder where your brand files live.
- Permission for that account to read, upload and tag files in the bucket.
- A Slack workspace, with the channels you want to share assets into.
- A folder layout you are happy browsing by, for example one folder per campaign or per asset type.

## Prompt

Build me a brand asset library app so our marketing team can find, preview and share the files we keep in Amazon S3 without logging into AWS or pinging an engineer. The people using it are marketers and designers, not engineers, so it should feel like a media library rather than a file system.

The main screen is a searchable grid of assets from a chosen bucket and key prefix. Use Amazon S3 List Objects (V2) with the prefix to load the objects, paginating with the continuation token since each page returns at most 1,000 keys. Each card shows an image preview plus the file name, file type, size and last modified date. The listing already returns size and last modified for every key, so use those directly and call Head Object for the content type and any richer metadata, fetching it lazily for the cards actually in view rather than calling Head Object for the whole bucket up front.

For previews, fetch the bytes with Get Object in a server side handler and render them in the grid. Images get a real thumbnail. Non image types like PDFs, video, fonts and archives get a clear file type badge instead of a broken preview. Load thumbnails lazily as cards scroll into view so opening the library does not download the entire bucket.

Tags come from Get Object Tagging, using a small deliberate vocabulary like campaign=spring-launch and status=approved. The grid can be filtered by file type, by folder (the key prefix segment) and by tag. Default the grid to status=approved so the safe choice is the first thing anyone sees, with an obvious control to widen the view to everything. Assets tagged status=retired must stay visible rather than being hidden, shown dimmed with a clear Retired badge so people can see the old logo exists and know not to reuse it.

Clicking an asset opens a detail panel with a bigger preview, the full metadata (key, folder, file type, size, last modified, storage class and every tag) and a download button backed by Get Object.

Users can upload new assets straight into the right folder with Put Object. Let them pick the destination folder from the folders already present under the prefix, set the correct content type from the file, and prompt them to tag the asset immediately after the upload succeeds so nothing lands untagged.

Tags are set and edited from the detail panel with Put Object Tagging, including quick actions to mark an asset approved or retired so people stop reusing outdated logos. Two rules matter here. Put Object Tagging replaces the entire tag set, so always read the current tags with Get Object Tagging first, merge the change, and write the full set back, otherwise editing one tag wipes the rest. Amazon S3 also caps objects at 10 tags, so enforce that in the UI with a clear message instead of letting the write fail.

Selecting one or more assets in the grid and hitting Share to Slack opens a composer where the user picks a channel and writes a short description. Populate the channel picker with List Channels from the Slack Bot integration, and post with Slack Bot Send a Message. Send one tidy message listing every selected asset with its name and file type plus the description, rather than one message per file. Use the Slack Bot integration for this, since posts should come from the bot identity. If any selected asset is tagged retired, warn the user before posting.

Remember each user's last used bucket, prefix, filter state and default Slack channel so the library opens where they left off. Keep a lightweight share history recording who shared which asset, when, and to which channel, and surface that asset's history in its detail panel.

## How to customize

- Change which bucket and folder the library opens on, and set a different default folder for new uploads.
- Adjust the tag vocabulary to match how your team works, for example swapping campaign names or adding a region or language tag.
- Change the default view, so the grid opens on every asset instead of only the approved ones.
- Set a default Slack channel for sharing, so the most common destination is preselected.

## FAQ

### Does everyone need an AWS login to use this?

No, and that is the point. The library connects to your Amazon S3 account once, then anyone with access to the app can browse, download, upload and share files without ever opening the AWS console.

### Will retired assets be hidden from the team?

No. Retired files stay visible but are clearly marked and visually dimmed, so people can see that an old logo still exists and understand they should not use it. The grid opens on approved assets only, so the safe choice is what everyone sees first.

### Can people upload new files from the app?

Yes. Anyone can upload a file straight into the folder you choose, and tag it right away so it shows up under the right campaign and status.

### How many tags can each file have?

Amazon S3 allows up to ten tags per file, so it is worth keeping the vocabulary small and deliberate. A status tag plus a campaign tag covers most teams, which leaves plenty of room to spare.

### What actually gets posted to Slack?

You select one or more assets, pick a channel, and add a short description. The app posts a single message listing the assets you chose with their names and file types, so the channel gets one tidy update instead of a pile of attachments.

### Will this work with files that are not images?

Yes. Images get a visual preview, and other file types like PDFs, videos, fonts and archives appear with a clear file type badge along with all the same details, tagging and sharing options.
