tctx is available on npm and JSR, making it easy to install with any JavaScript package manager.

​
Package Managers

npm install tctx

​
JSR (JavaScript Registry)

For Deno or other runtimes that support JSR, you can install tctx from the JavaScript Registry: 
deno add @mr/tracecontext
The npm package is published as tctx while the JSR package is published as @mr/tracecontext.

​
Verify Installation

After installation, verify that tctx is working correctly: 
import * as traceparent from 'tctx/traceparent';
import * as tracestate from 'tctx/tracestate';

const parent = traceparent.make();
console.log(String(parent));
// Output: 00-4bf92f3577b34da6a3ce929d0e0e4736-00f067aa0ba902b7-01

​
Dependencies

tctx has minimal dependencies:
  • @lukeed/csprng - Cryptographically secure pseudo-random number generation for creating trace IDs
This single dependency ensures secure random ID generation while keeping the package lightweight.

​
TypeScript Support

tctx includes full TypeScript type definitions out of the box. No additional @types packages are required. 
import * as traceparent from 'tctx/traceparent';
import type { Traceparent } from 'tctx/traceparent';

const parent: Traceparent = traceparent.make();

​
Runtime Compatibility

tctx works seamlessly across all major JavaScript runtimes:
  • Node.js - Version 14 and above
  • Deno - All versions
  • Bun - All versions
  • Browsers - All modern browsers (ES2015+)
  • Edge Functions - Cloudflare Workers, Vercel Edge, Deno Deploy, etc.
tctx is designed to be runtime-agnostic with no Node.js-specific APIs, making it perfect for edge computing environments.
