Wrangler Config Companion (VS Code)

Validates wrangler.toml (Cloudflare Workers) — required fields (name/main/compatibility_date), date format, and missing binding/id fields in kv_namespaces/r2_buckets/d1_databases entries. No data leaves your editor.

v0.1, new niche. Not a port from the Gap Hunter Labs IntelliJ- family catalog. Evidence, direct from Cloudflare's own repo: issue cloudflare/workers-sdk#1165 ("Feature Request: improve the wrangler.toml config experience"), confirmed textually — "only limited validation of the wrangler.toml file is currently provided."

What it checks

Live, on any wrangler.toml:

• Missing top-level name, main, or compatibility_date.
• compatibility_date not in YYYY-MM-DD format.
• A [[kv_namespaces]] entry missing binding or id.
• A [[r2_buckets]] entry missing binding or bucket_name.
• A [[d1_databases]] entry missing binding or database_id.

v0.1 scope, honestly noted: a hand-rolled parser for the TOML subset wrangler.toml actually uses (top-level key=value, [section] tables, [[array.of.tables]]) — not a general TOML parser (no multi-line strings, no inline tables). main is checked as the modern entry-point field; the older [build] command-based convention isn't specially recognized.
