newman-env

Command-line helper for updating Postman environment variables before running Newman. Use it to patch values in an exported Postman environment JSON so your CI/CD runs always target the right endpoints.

Features

• Update one or more environment variables from the CLI.
• Overwrite the source file or write to a separate output path.
• Leaves values untouched when a key does not exist in the environment file.

Installation

npm install -g newman-env

Usage

Export your Postman Environment as JSON, then run:

newman-env run postman-environments.json --env-var endpoint=http://localhost:3000 --env-var [email protected]

To write to a new file:

newman-env run postman-environments.json -o postman-environments.updated.json --env-var endpoint=http://localhost:3000

Command

newman-env run <environment-file> [options]

Options

• -o, --output [path] Specify an output environment file path. Defaults to overwriting the input file.
• --env-var <key=value> Set an environment variable. Repeat for multiple values.

Notes

• The input file must be a valid Postman environment JSON with a values array of { key, value } entries.
• If the output directory does not exist, the command fails.

Development
