Convert all source files from JavaScript to TypeScript while preserving the existing API and behavior. This migration adds type safety without breaking changes: - Convert src/*.js to src/*.ts with proper type annotations - Add src/types.ts with shared type definitions - Update babel configuration to support TypeScript compilation - Add tsconfig.json for type checking - Update package.json with TypeScript dependencies (@babel/preset-typescript) - Upgrade to @babel/register and modern rollup plugins - Generate TypeScript declaration files in types/ directory - All 33 existing tests continue to pass 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The previous README documented APIs that don't exist in the current codebase (new SuperPipe(), .listenTo(), .setDep(), etc.). This rewrite documents the actual API based on the implementation: - superpipe(deps) factory function - Pipeline fluent API: .input(), .pipe(), .error(), .end() - Declarative pipeline definitions - Special features: next/set inputs, boolean flow control, not/optional pipes, output mapping, plain object returns - Error handling patterns - TypeScript support section 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Replace CircleCI with GitHub Actions for CI/CD: - Test on Node 16, 18, 20, and 22 - Run type checking, unit tests, and build on every PR and push to master - Upload coverage to Coveralls after tests pass - Use npm ci for faster, reproducible installs The old CircleCI config tested on Node 6, 8, 10 which are no longer supported. This aligns with the updated minimum Node version (12+). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Cover the edge case where set() is called on a pipe that has no output defined. This exercises the guard in checkFulfillment that returns early when output or fulfilled is undefined. Restores 100% line coverage. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Remove optional chaining from throwError since previousPipeState is always defined when an error is thrown (errors are triggered by pipes). This eliminates the uncovered branch from optional chaining. Coverage now at 100% for statements, branches, functions, and lines. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

None. The API remains identical - this is purely an internal migration.
