Charts and Data Visualization Components
How FlinUI's 25 chart components render data visualizations with pure FLIN markup -- from line charts to treemaps, all declarative, reactive, and zero-dependency.
Persistence in the Browser
How we made FlinDB work in the browser -- from SSR with hot module reload, to two-way data binding, form submission through server actions, and the persistence bug that almost broke everything.
409 Built-in Functions: The Complete Standard Library
How FLIN ships 409 built-in functions with zero imports -- text, math, time, HTTP, crypto, validation, and more, all available from the first line of code.
31 String Methods Built Into the Language
How we expanded FLIN's string methods from 11 basic operations to 31 comprehensive text manipulation functions in Session 050 -- covering search, transformation, validation, and encoding.
Math, Statistics, and Geometry Functions
How FLIN ships a complete mathematics library -- 100+ functions covering arithmetic, trigonometry, statistics, and geometry -- built into the language runtime with zero imports.
Time and Timezone Functions
How FLIN's built-in time system handles dates, durations, timezones, and formatting without a single import -- covering 26 time functions and natural duration syntax.
HTTP Client Built Into the Language
How FLIN ships a complete HTTP client as a built-in language feature -- GET, POST, PUT, DELETE with JSON handling, timeouts, retries, and headers, all without importing a library.
Security Functions: Crypto, JWT, Argon2
How FLIN ships production-grade security functions as built-ins -- password hashing with Argon2, JWT signing and verification, HMAC, encryption, and secure random generation.
Reduce, Map, Filter: Higher-Order Functions
How FLIN implements higher-order functions -- map, filter, reduce, flat_map, zip_with, and more -- as built-in list methods with concise lambda syntax and full type inference.
151 FlinUI Components Built by AI Agents
How we used parallel AI agents to build 151 FlinUI components in a single extended session -- the orchestration strategy, quality controls, and what it reveals about AI-assisted development.
FLIN's Embedded HTTP Server
How FLIN ships a production-grade HTTP server inside the runtime itself -- no Express, no Flask, no external dependency. Just run your .flin file and the server is already there.
Graph Queries and Semantic Search
How FlinDB implements graph traversal algorithms and AI-powered semantic search with BM25, vector similarity, and hybrid Reciprocal Rank Fusion -- all built into a single embedded database.
