Greptile Summary

This PR adds a new NATS messaging broker template (blueprints/nats/) with a pinned Docker image (nats:2.10.24-alpine), a config file mount that enables token-based authentication and WebSocket support, monitoring and WebSocket domains, and registers the template in meta.json. The template structure is sound and consistent with repository conventions.

Key issues found:

• Accidental Strapi deletion: The entire Strapi entry was removed from meta.json — this is unrelated to the NATS PR and appears to be caused by a merge conflict or outdated base branch. The blueprints/strapi/ directory still exists, so Strapi would silently disappear from the template registry.
• Unused data volume: nats-data:/data is mounted in docker-compose.yml but the nats.conf does not include a store_dir directive, so the volume will never be written to unless JetStream is manually configured post-deploy.
• Logo format: A JPEG (nats.jpeg) is used instead of the preferred SVG format per contribution guidelines.

Confidence Score: 2/5

• Not safe to merge — the accidental Strapi entry deletion from meta.json must be resolved first.
• The NATS blueprint itself is well-structured and follows conventions, but the unintentional removal of the Strapi entry from meta.json is a blocking issue. Merging as-is would silently remove a working template from the registry without any corresponding blueprint deletion.
• meta.json requires immediate attention to restore the accidentally deleted Strapi entry.

   Accidental Strapi entry deletion

   This PR removes the entire Strapi entry from meta.json, but the PR description only mentions adding the NATS template. This appears to be an accidental deletion — possibly caused by a merge conflict or working off an outdated base branch.

   The blueprints/strapi/ directory still exists in the repository, so removing its metadata entry would make it disappear from the template registry without removing the underlying blueprint. Please restore the Strapi entry.

   Logo should prefer SVG format

   Per the project's contribution guidelines (AGENTS.md), logos should be SVG format at approximately 128×128px. A JPEG logo may appear blurry or pixelated at different display sizes. Consider replacing nats.jpeg with an SVG version — the official NATS logo is available as an SVG from the NATS branding resources.

Volume mounted but JetStream not configured

The nats-data:/data volume is declared and mounted, but the nats.conf file (defined in template.toml) does not include a store_dir directive pointing to /data. Without store_dir: /data in the NATS config, JetStream persistence won't use this volume and it will remain empty.

If JetStream is not intended to be enabled, the volume can be removed. If persistence is desired, add store_dir: /data and jetstream {} to the config:

jetstream {
  store_dir: /data
}

port 8080 works perfect

curl -i -N --http1.1 \
-H "Connection: Upgrade" \
-H "Upgrade: websocket" \
-H "Sec-WebSocket-Version: 13" \
-H "Sec-WebSocket-Key: dGhlIHNhbXBsZSBub25jZQ==" \
https://nats.example.com

port 8222 works fine.
