Runtimes

Tenace is ESM only and has no runtime dependencies. It runs on:

Runtime	Version
Node.js	22.18 or later
Bun	latest, tested in CI
Cloudflare Workers	with or without the nodejs_compat flag

The CI of the repository runs the test suite on Node.js 22, 24, and 26 and on Bun, and runs the built bundle in workerd through Miniflare, with and without nodejs_compat.

The package has no static node: import. Two features depend on the runtime:

• diagnostics_channel. Tenace loads it with process.getBuiltinModule() the first time an execution runs. Where it is missing, such as Workers without nodejs_compat, nothing is published and nothing fails. See diagnostics_channel.
• Timers. The system clock uses the global setTimeout and clearTimeout, which every supported runtime provides. It chains them for delays beyond their limit of 2^31 - 1 ms.

The @julr/tenace-otel package depends only on @opentelemetry/api, and runs wherever an OpenTelemetry SDK does.
