Tutorials
End-to-end builds. Each tutorial starts from an empty blueprint and ends with something running: APIs, logins, dashboards, email, uploads and AI.
Building User Authentication Build user authentication: the sign-in flow, login tokens, 2FA and the scope checks around them, gating pages and sections, and a hardening checklist. Creating a REST API A complete CRUD REST API: list with filters, create with validation, read, update and delete, with paging, error replies, scopes and testing it. Dashboard with Charts Aggregate storage data and render it as a live dashboard with charts: get the data, render the page and keep it fast, with a checklist to finish on. File Upload & Processing Accept an upload from a page or an API, store it as an asset and process it safely in the background, with the safety rules every upload flow needs. Email System Setup Transactional email: sending from a flow, templates that survive edits, bulk and scheduled mail, delivery handling and the discipline behind deliverability. Third-Party Integrations Call external APIs, receive their webhooks, keep data in sync, keep credentials out of the canvas and handle failures with a few operational rules. Building AI Endpoints Add Claude to a blueprint: messages, structured JSON replies, streaming to the browser, classify and route, tools, cost control and batch jobs. Building a Login Page Passwordless login: email a code, verify it into a session token, and build the form page around it, with notes from running it in practice. Building a Reporting API A reporting API: aggregations over storage, answered as a CSV or XLSX download or sent as a scheduled email, with notes from running it in practice. Handling City Filter Uploads Parse uploaded CSV or XLSX locations and keep only the rows inside your city or radius, then validate, enrich and store the rows that are left. Building an API with Locking An API with locking: claim a lock around read-modify-write sections, keep the critical section small, and always release the lock again. Local Home Automation Automate the building around a Nano: which radio to buy, the daemon stack, configuration, discovering and adopting devices, the blocks and a first flow.
