Picture this: you've just pulled a script from the internet. You don't know the author. You don't know what it does. In Node.js, running it hands over your file system, your network, your environment variables, no questions asked. One node script.js, and you're trusting a stranger with everything.
Now picture running that same script in Deno. Nothing happens. No file reads. No network calls. Silence, until you decide otherwise. That single moment, permission denied by default, is the whole philosophy of this book in miniature. It's not paranoia. It's control, handed back to you.
This book was written to make that control feel natural, not intimidating. You'll build a real API. You'll watch it reject bad data before it ever touches your database. You'll compile it into a file that runs anywhere. And somewhere along the way, you'll stop asking "how do I make this work in Deno" and start asking "why would I ever build it any other way."
What's Inside- The philosophy and architecture behind Deno: V8, Rust, and Tokio, and why they matter to you
- Native TypeScript support, from basic type checking to real design patterns
- Deno's permission system, including scoping, sandboxing, and dependency risk
- Building web servers and REST APIs, plus WebSockets and Server-Sent Events
- Data persistence with Deno KV, and connecting to PostgreSQL, MySQL, and MongoDB
- Testing, benchmarking, profiling, and scaling with clustering and load balancing
- Deployment: standalone executables, Docker, and Deno Deploy
- Monitoring and logging for real production traffic
- A full appendix on migrating an existing Node.js project, step by step
This book is written for developers who already know JavaScript or TypeScript and want to build real, dependable backend applications. Whether you're coming from Node.js and curious what all the difference is about, or starting fresh and want a runtime that keeps security built in from day one, you'll find a clear, patient explanation waiting for you, one that never assumes you already know the answer, but never talks down to you either.
Every line of code you've ever run has trusted something, a package, a runtime, a stranger's script. This book teaches you how to stop trusting blindly, and start building deliberately. Turn the page, open your terminal, and write your first line of Deno. The runtime that changes how you think about security is one command away. Are you ready to run it?

Information regarding the right of withdrawal
Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.
The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.
To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.
You shall send back the goods or hand them over to California Books, Fort Wayne, Indiana, U.S.A., without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.
Exceptions to the right of withdrawal
The right of withdrawal does not apply to:
- The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
- The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.
