Summary by CodeRabbit

• New Features

  • Added a unified proxy service to serve frontend and backend together; improved proxy behavior, security headers, gzip, and connection upgrade handling.

• Configuration

  • Renamed API_URL to BASE_URL across setup and prompts; setup now collects BASE_URL (public URL, no trailing slash).
  • Removed direct public port mappings and legacy cloud proxy toggle.

• Documentation

  • Updated install/setup steps to reference BASE_URL and its usage.

• Chores

  • Updated service images to v5.0.0.

📝 Walkthrough

Walkthrough

Adds an nginx reverse-proxy service and consolidated config, renames frontend API variable to BASE_URL across env and scripts, removes direct service port mappings, updates compose images to v5.0.0, and updates README/configure.sh to reference BASE_URL and proxy-based access on port 80.

Changes

Cohort / File(s)	Summary
Environment & scripts \.env.example`, `configure.sh``	Replaced API_URL with BASE_URL (comment: public URL without trailing slash). Added OIDC_PROMPT and CLIENT_IP_HEADER entries; removed CLOUDFLARE_PROXY_ENABLED. configure.sh prompts for BASE_URL, trims trailing slashes, and writes it to .env; Cloudflare prompt removed.
Compose / services \compose.yaml``	Bumped frontend/API images to v5.0.0. Removed published ports for swetrix and swetrix-api. Swapped frontend env API_URL→BASE_URL. Added nginx-proxy service (nginx:1.29.4-alpine) exposing 80:80, with health-based depends_on, links, and config volume mount.
Nginx configuration \nginx/config``	New consolidated nginx config on port 80: connection-upgrade map, security headers, gzip settings, and proxying rules: / → swetrix:3000 and /backend/ → swetrix-api:5005 with expanded proxy headers, buffering, and upgrade handling; removed previous internal server block.
Documentation \README.md``	Updated setup steps and messaging to reference BASE_URL (default http://localhost) and to indicate access via the BASE_URL rather than direct service ports.

Poem

🐰 I hopped where ports once loudly spoke,
Now nginx listens on a single stroke,
BASE_URL leads every roaming guest,
Backend and frontend settled to rest,
I rabbit-clap for this tidy nest. 🥕

In `@configure.sh`:
- Around line 254-264: In the while loop that reads and normalizes base_url,
change the single-slash trim (base_url="${base_url%/}") to remove all trailing
slashes; update the normalization for the variable base_url after the read
(e.g., replace that line with a command that strips all trailing slashes such as
using sed: base_url="$(echo \"$base_url\" | sed 's:/*$::')" or use bash extglob
to remove all slashes) so values like "https://example.com///" become
"https://example.com" before writing BASE_URL to .env.

In `@compose.yaml`:
- Line 21: The Docker Compose service image currently references a non-existent
tag "swetrix/swetrix-api:v5.0.0"; update the image value to a valid existing tag
(for example replace "swetrix/swetrix-api:v5.0.0" with
"swetrix/swetrix-api:v4.1.0") or change it to the correct released tag once
v5.0.0 is published so that the image pull succeeds.
- Line 4: Replace the non-existent image tags by updating the Docker image
references: change swetrix/swetrix-fe:v5.0.0 to swetrix/swetrix-fe:v4.1.0 and
swetrix/swetrix-api:v5.0.0 to swetrix/swetrix-api:v4.1.0 (or another verified
existing tag); locate the two image lines that mention "swetrix/swetrix-fe" and
"swetrix/swetrix-api" and update their tag suffixes accordingly, then re-run the
compose deployment to confirm the images pull successfully.

🧹 Nitpick comments (1)

compose.yaml (1)

121-123: Consider removing deprecated links directive.

The links directive is deprecated in Docker Compose v3+. Services on the same Compose network can already communicate by service name. With depends_on already ensuring startup order, links is redundant.

♻️ Suggested removal
