Cloudflare’s Developer Week 2025 introduced groundbreaking updates for modern application development. If you haven’t explored Cloudflare’s platform yet, now is the perfect time. Below are the key highlights and practical implementations.
You Should Know:
1. Cloudflare Workers Enhancements
Cloudflare Workers now support larger scripts (up to 20MB) and longer execution times (up to 30 minutes).
Deploy a Worker:
Install Wrangler (Cloudflare Workers CLI) npm install -g wrangler Authenticate wrangler login Create & deploy a new Worker wrangler init my-worker cd my-worker wrangler deploy
2. D1 Database (Serverless SQLite)
Cloudflare’s D1 Database offers serverless SQLite with zero-config scaling.
Example Query:
-- Create a table
CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT);
-- Insert data
INSERT INTO users (name) VALUES ('Alice'), ('Bob');
-- Query data
SELECT FROM users;
3. R2 Storage Auto-Scaling
R2 now supports auto-scaling with S3-compatible API.
Upload a file via CLI:
Install AWS CLI (if not installed) curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip" unzip awscliv2.zip sudo ./aws/install Configure R2 credentials aws configure --profile r2 Enter: AWS Access Key: YOUR_R2_ACCESS_KEY AWS Secret Key: YOUR_R2_SECRET_KEY Region: auto Output format: json Upload a file aws s3 cp my-file.txt s3://my-bucket --endpoint-url https://myaccount.r2.cloudflarestorage.com
4. Cloudflare Pages with WebAssembly (WASM)
Deploy WASM-powered apps directly to Cloudflare Pages.
Example `_config.yml`:
name: my-wasm-app build_command: wasm-pack build output_dir: ./pkg
5. AI Gateway (Beta)
A unified API for AI model inference with caching and rate limiting.
Call OpenAI via AI Gateway:
curl -X POST https://gateway.ai.cloudflare.com/v1/openai/completions \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{"model":"text-davinci-003","prompt":"Hello, world!"}'
What Undercode Say:

– Workers now handle heavier workloads.
– D1 Database simplifies serverless SQL.
– R2 Storage is cost-effective and scalable.
– WASM on Pages unlocks high-performance web apps.
– AI Gateway streamlines AI model deployments.
Linux/Windows Commands Reference:
