The Bridge Language — VS Code Extension

Full IDE support for The Bridge: a declarative dataflow language for GraphQL. Wire data between APIs and schema fields using .bridge files — no resolvers, no codegen, no plumbing.

Features

Language Server (LSP)

• Real-time diagnostics — syntax errors and semantic issues highlighted as you type
• Semantic validation — undeclared handles, unsatisfied with dependencies, and unknown wire targets flagged immediately
• Hover information — hover over any handle, dependency, or declaration to see its type and source
  • Bridge hover: type/field name, handle count, wire count
  • Tool hover: function name, deps, wires
  • Define hover: subgraph details
  • Const hover: name and raw value
• Error recovery — partial AST is built even on broken files, so diagnostics remain accurate while you're mid-edit

Syntax Highlighting

• Full syntax highlighting for .bridge files (language version 1.5)
• Block keyword highlighting: version, const, tool, define, bridge
• Wire operator colouring: <- (pull), || (falsy-coalesce), ?? (nullish gate), catch (error boundary), : (pipe)
• force <handle> and force <handle> catch null keyword highlighting
• Distinct colours for GraphQL type/field targets in bridge declarations
• Tool handle and alias highlighting
• Built-in handle highlighting: input, output, context
• Constant assignment colouring: .property = value
• HTTP method constants: GET, POST, PUT, DELETE, PATCH, HEAD, OPTIONS
• Unquoted URL path values (e.g. /search, /api/v1/forecast)
• Array mapping syntax: source[] as iter { … }
• on error fallback declarations inside tool blocks
• String, number, boolean, and null literals

Editor Integration

• Line comment toggling (#)
• Bracket matching for {} and []
• Automatic language detection for *.bridge files

Installation

Search for "The Bridge Language" in the VS Code Extensions panel, or install from the terminal:
