-As of Wrangler v3.91.0, Wrangler supports both JSON (`wrangler.json`) and TOML (`wrangler.toml`) for its configuration file. Prior to that version, only `wrangler.toml` was supported. The format of Wrangler's configuration file is exactly the same across both languages, except that the syntax is `JSON` rather than `TOML`. Throughout this page and the rest of Cloudflare's documentation config snippets are provided as both JSON and TOML.
