cross-env is an npm-distributed CLI tool that lets developers set and use environment variables in npm scripts with POSIX syntax, working identically on Windows, macOS, and Linux. It is feature-complete and in maintenance mode, with no new features planned.

Use cases

• set NODE_ENV=production in npm scripts that work on Windows
• run cross-platform build scripts with environment variables
• use $VAR syntax in scripts on Windows
• set multiple environment variables in a single npm script
• share environment variables between parent and child npm scripts
• avoid Windows cmd syntax differences in CI scripts

When to choose

• your npm scripts set environment variables and must run on Windows and Unix
• you want one script syntax instead of per-platform workarounds
• you need POSIX-style $VAR expansion in cross-platform shell commands

When to avoid

• you only target POSIX systems and can set env vars natively
• you need new features - the project is done and in maintenance mode
• you are on Node.js 18 or lower and need version 7 instead
