FLIN
The language that replaces 47 technologies
A compiled, full-stack programming language built from scratch in Rust. One syntax for frontend, backend, database, and tooling. 3,200+ tests. 180 embedded UI components. Zero npm dependencies.
Building FLIN
#132 -- Extracting Text From CSV, XLSX, RTF, and XML
How FLIN extracts searchable text from CSV, XLSX, RTF, and XML files with built-in parsers.
#085 -- Design Tokens and Theming System
How FlinUI's design token system provides 50+ tokens for colors, spacing, typography, and shadows -- enabling consistent theming and dark mode across 365+ components.
#126 -- File Storage With 4 Backends
How FLIN provides unified file storage across local filesystem, Amazon S3, Cloudflare R2, and Google Cloud Storage -- all with zero configuration.
#127 -- The Storage Backend Trait Pattern
How a single Rust trait abstraction allows FLIN to support any storage backend with a unified API.
#130 -- Text Chunking Strategies
How FLIN splits documents into semantically meaningful chunks for embedding and retrieval.
#133 -- Semantic Auto-Conversion
How FLIN automatically converts between file formats using semantic understanding of content structure.
#077 -- Introspection and Reflection at Runtime
How FLIN's introspection system lets programs examine their own types, fields, and structures at runtime -- enabling dynamic forms, serialization, and debugging without sacrificing type safety.
#089 -- Scoped CSS and Computed Styles
How FLIN's scoped CSS system prevents style leakage between components and enables computed styles that react to state changes -- combining CSS isolation with runtime dynamism.
#102 -- Guards: Declarative Security for Routes
How FLIN's guard system provides declarative, composable access control for routes -- auth, roles, rate limiting, CSRF, IP whitelists, and time-based access in single-line declarations.
#148 -- 30 TODOs, 5 Production Panics, 0 Security Issues
The audit results: 30 TODO markers, 5 production panic calls, and zero security vulnerabilities.
#149 -- The Audit Fix Plan
The systematic plan to address every finding from the FLIN codebase audit.
#150 -- Function Audit Day 7 Complete
The exhaustive function-by-function audit of all 409+ built-in functions on day 7.
