@flowview/compiler

The FlowView compiler parses trusted .flow template source and compiles it to plain JavaScript render functions. It uses the bundled WASM compiler; npm consumers do not need Rust, Cargo, or a native FlowView executable.

import { compileFlowview } from "@flowview/compiler";

const { code, warnings } = compileFlowview("<h1>{{ context.title }}</h1>", {
  filename: "page.flow",
});

compileFlowview returns generated code, optional source maps, and structured warnings. Compilation errors throw FlowviewCompilerError, whose diagnostics contain the compiler's message, severity, code, filename, line, column, and UTF-8 byte span. The compiler validates expressions but does not evaluate them.

FlowView templates are trusted source code. Normal interpolation ({{ value }}) escapes HTML. Triple braces ({{{ value }}}) are the only raw interpolation path and require an already trusted string. FlowView does not sanitize HTML. Mixed static text and interpolation in one attribute value is unsupported. track is accepted but has no rendering effect and produces FV0015.
