# Wrangler configuration for Cloudflare Workers
# Docs: https://developers.cloudflare.com/workers/wrangler/configuration/
# This template aims to enumerate the major, commonly used options in wrangler.toml.
# Not every experimental/beta option is listed; prefer official docs for edge cases.

# Required: unique Worker name in your Cloudflare account.
name = "workertemplate"

# Entry point for a Modules Worker. Use .ts/.mjs if needed.
# If you ship a Service Worker script instead of Modules, see [build.upload] below.
main = "index.js"

# Required: locks your Worker to a specific runtime API version.
# Bump intentionally after testing: https://developers.cloudflare.com/workers/platform/compatibility-dates/
compatibility_date = "2025-09-09"

# Optional: granular runtime feature flags; use sparingly.
# Example: ["nodejs_compat"] or other flags listed in docs.
# https://developers.cloudflare.com/workers/platform/compatibility-dates/#compatibility-flags
# compatibility_flags = []

# Optional: enable Node.js API polyfills (fetch-based). Prefer compatibility_flags where appropriate.
# node_compat = true

# Account to deploy under (auto-detected by login, but set explicitly for CI).
# https://developers.cloudflare.com/workers/wrangler/commands/#login
# account_id = ""

# Deploy to *.workers.dev when true (useful without routes/zone).
# workers_dev = true

# Retain vars across publish if they already exist on the server (helps CI idempotency).
keep_vars = true

# Choose pricing/limits model. "bundled" (default) or "unbound".
# https://developers.cloudflare.com/workers/platform/pricing/#usage-models
# usage_model = "bundled"

# Routing
# Simple route list (no per-route options). Requires a zone.
# routes = ["example.com/*", "api.example.com/*"]

# Advanced per-route objects. Use either routes above OR [[routes]] blocks below.
# [[routes]]
# pattern = "example.com/*"
# zone_name = "example.com"   # or zone_id = "..."
# # Optional: custom placement per route (rare). See [placement] below.
# # script = "<another-worker-name>"  # only when defining routes for other scripts

# Triggers (CRON)
# CRON schedules in crontab format (UTC). Your Worker must export a scheduled handler.
# https://developers.cloudflare.com/workers/configuration/cron-triggers/
# [triggers]
# crons = ["*/5 * * * *"]

# Observability
# Collect platform metrics/traces; view in Dashboard > Observability.
[observability]
enabled = true
# head_sampling_rate = 1.0  # 0.0–1.0 fraction to sample traces, when supported.

# Smart Placement
# Let Cloudflare place your Worker near the origin/data location automatically.
# https://developers.cloudflare.com/workers/configuration/smart-placement/
# [placement]
# mode = "smart"  # "smart" or "off" (default if omitted)

# Environment Variables (plaintext)
# Do NOT store secrets here. For secrets, use `wrangler secret put`.
# https://developers.cloudflare.com/workers/wrangler/configuration/#environment-variables
# [vars]
# NODE_ENV = "production"
# API_BASE_URL = "https://api.example.com"

# Secrets
# Define at deploy-time:
# $ wrangler secret put MY_SECRET
# They do not appear in wrangler.toml by design.

# Static Assets (Workers Assets)
# Serve static files bundled into your Worker and expose as a binding.

# Switch between Modules and Service Worker upload formats.
# [build.upload]

# Durable Objects (fully commented)

# https://developers.cloudflare.com/workers/runtime-apis/durable-objects/
# [durable_objects]
# bindings = [
#   { name = "MY_DO", class_name = "MyDurableObject" }

# Per-Environment Overrides
# Any top-level key can be nested under [env.<name>] to override for that env.
# Example: production overrides.
# [env.production]
# route = "api.example.com/*"
# vars = { NODE_ENV = "production" }
# [env.production.kv_namespaces]
# # env-scoped tables must be re-declared within env blocks as needed.

# Notes:
# • Secrets are managed via `wrangler secret` and never stored here.
# • Avoid enabling flags you don’t need. Test changes behind environments.
# • When using routes, ensure the zone is in the same account as `account_id`.
# • Prefer Modules syntax for new Workers.
