Renders the durable file attachments introduced in #24280 in the chat interface. Without this, attachments were stored and served correctly but the UI showed raw file parts with no previews or download UX. Every attachment gets a download affordance, split into three rendering tiers: - **Images** — thumbnail with a hover/focus overlay containing a download link. `onFocusCapture`/`onBlurCapture` with `contains(relatedTarget)` keeps the overlay open while tabbing between the image and its download link. - **Text-like files** (`text/*`, `application/json`) — expandable preview button with loading + error-with-retry states and the same download overlay. Preview fetches throw a typed `FetchTextAttachmentError` with a `.status` field instead of a stringly-typed error. - **Everything else** — compact `FileCard` with extension badge, filename, and download link. User-side and assistant-side rendering now share `AttachmentBlocks.tsx` (`AttachmentPreviewFrame`, `TextAttachmentButton`, `ImageAttachmentButton`, `FileCard`, plus `getAttachmentHref`/`getAttachmentName`) instead of two near-duplicate implementations. The text-attachment overlay anchors to the preview surface so the download button stays pinned even when a loading/error status line widens the row below. `ComputerRenderer` detects when a screenshot was stored as a durable attachment (`attachment_file_id`) and suppresses the stale base64 rendering — the screenshot appears as a proper file part instead. `ToolLabel` shows the attached filename for `attach_file` tool calls. Storybook coverage in `ConversationTimeline.stories.tsx` was expanded to cover every tier (single/multiple images, inline + file-id text, JSON, download-only files, fetch-failure retry, mixed attachments + file references) with play-function assertions. <img width="811" height="150" alt="image" src="https://github.com/user-attachments/assets/27c71081-3502-4e80-92a7-d8adf1ff9323" /> ## Cleanup Per Mathias' post-merge suggestion on #24280, this PR also relocates `coderd/chatfiles` → `coderd/x/chatfiles` so the durable-attachment helpers live beside the rest of the `chatd` experimental surface. Closes CODAGT-91
Coder enables organizations to set up development environments in their public or private cloud infrastructure. Cloud development environments are defined with Terraform, connected through a secure high-speed Wireguard® tunnel, and automatically shut down when not used to save on costs. Coder gives engineering teams the flexibility to use the cloud for workloads most beneficial to them.
- Define cloud development environments in Terraform
- EC2 VMs, Kubernetes Pods, Docker Containers, etc.
- Automatically shutdown idle resources to save on costs
- Onboard developers in seconds instead of days
Quickstart
The most convenient way to try Coder is to install it on your local machine and experiment with provisioning cloud development environments using Docker (works on Linux, macOS, and Windows).
# First, install Coder
curl -L https://coder.com/install.sh | sh
# Start the Coder server (caches data in ~/.cache/coder)
coder server
# Navigate to http://localhost:3000 to create your initial user,
# create a Docker template and provision a workspace
Install
The easiest way to install Coder is to use our
install script for Linux
and macOS. For Windows, use the latest ..._installer.exe file from GitHub
Releases.
curl -L https://coder.com/install.sh | sh
You can run the install script with --dry-run to see the commands that will be used to install without executing them. Run the install script with --help for additional flags.
See install for additional methods.
Once installed, you can start a production deployment with a single command:
# Automatically sets up an external access URL on *.try.coder.app
coder server
# Requires a PostgreSQL instance (version 13 or higher) and external access URL
coder server --postgres-url <url> --access-url <url>
Use coder --help to get a list of flags and environment variables. Use our install guides for a complete walkthrough.
