If a chapter helped you debug something or finally made sense of the event loop, toss me a coffee. No strings attached.

• My genuine thanks, and you're keeping the book free for everyone.

Each chapter takes days of research, testing code across Node versions, and making sure the examples actually work. This helps cover that time and lets me say no to ads or paywalls.

• Early access to new chapters before they go live

• Your name in the supporters section (only if you want)

Got a Node.js concept you've always struggled with? Or something you wish existed but can't find good material on? Tell me what you want covered and I'll write a full chapter on it. The chapter goes into the free book for everyone - you're basically sponsoring knowledge for the whole community.

• All rewards above

• You get to shape what gets written

• Direct input on the chapter structure

• Special mention in that chapter's webpage

• Thank you.
