CommonJS CommonJS — require() works on every Node.js version we test

travis-deploy-once ships CommonJS only. require("travis-deploy-once") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=6. import "travis-deploy-once" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

What to do

  1. require("travis-deploy-once") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=6.
  2. From ES modules use the default import: import travisDeployOnce from "travis-deploy-once"; then destructure. Named imports only work when Node.js can statically detect the exports.
  3. TypeScript: no types are available for travis-deploy-once; declare the module yourself if you need them.
  4. This package is deprecated: We recommend to use Travis Build Stages instead
