+++ title = "Define Cloudflare Workers script resource — WASM artifact, D1 binding, environment variables" priority = 7 status = "todo" ticket_type = "task" dependencies = ["2d1371", "d0da0b", "07cafb", "efee79"] +++
Infrastructure is managed with OpenTofu using the Cloudflare provider.Trages resolved:
- 07cafb: D1 binding — use
cloudflare_d1_database.db.iddirectly; OpenTofu dependency graph handles ordering. No two-phase apply or data source needed. - efee79: Correct resource name —
cloudflare_workers_script(plural, confirmed from provider v4 source).
Every block must have a comment.
```hcl # infra/worker.tfCloudflare Workers script for the quotesdb API.
Compiled from the api binary targeting wasm32-unknown-unknown.
The Wasm artifact must be built before running tofu apply:
cargo build --release --target wasm32-unknown-unknown --bin api
resource "cloudflare_workers_script" "api" { account_id = var.cloudflare_account_id
Script name used in Cloudflare dashboard and for routing.
name = "quotesdb-api"
Compiled Wasm binary content, base64-encoded.
Path is relative to the infra/ directory.
content = filebase64("../target/wasm32-unknown-unknown/release/api.wasm")
D1 database binding — referenced in workers-rs code as env.DB.
database_id is resolved at apply time from the D1 resource output.
OpenTofu automatically creates the D1 database before this script
because of the attribute reference below (no explicit depends_on needed).
d1_database_binding { name = "DB" database_id = cloudflare_d1_database.db.id }
Workers runtime compatibility date.
compatibility_date = "2024-09-23" }
</implementation>
<notes>
- The `content` attribute expects base64-encoded script bytes. For a Wasm Worker, this is the raw compiled Wasm file, not a JS bundle.
- The binding `name = "DB"` must match exactly what the workers-rs API code uses (`env.DB`). Verify this in `src/bin/api/main.rs`.
- `(known after apply)` for `database_id` in `tofu plan` is expected and correct — OpenTofu resolves it at apply time.
- The Wasm binary must be compiled before `tofu apply`. This is handled by the Gitea Actions CI/CD workflow (ticket to be created; also see ticket 5137d7 for the UI workflow pattern).
