Initialize a Worker project using wrangler init, which scaffolds your project structure and creates a wrangler.toml configuration file. This file defines your Worker's metadata, environment variables, and resource bindings needed for deployment to Cloudflare.

Add binding configurations to your wrangler.toml file specifying the database name or R2 bucket. Wrangler injects these bindings as global objects in your Worker code, enabling direct database queries and object storage operations without separate connection setup.

Yes, wrangler supports multi-environment deployments through environment blocks in wrangler.toml. Define separate configurations for each environment with distinct bindings, variables, and routes, then deploy using wrangler deploy --env [environment-name].

Define variables and secrets in environment-specific blocks within wrangler.toml or use wrangler secret put to store sensitive values securely. Wrangler automatically injects these into your Worker runtime, keeping credentials out of source code.

Yes, wrangler handles bindings for KV namespaces, Durable Objects, Queues, and other Cloudflare services. Configure each binding type in wrangler.toml with its namespace ID or class name, and access them as injected globals in your Worker code.

Run wrangler dev to start a local development server that simulates your Worker environment with all configured bindings. This allows testing against real D1 databases, R2 buckets, and KV namespaces before pushing changes to live environments.
