Searches through files and replaces references to environment variables with the value of the named environment variable.
I use this to replace environment variables in config files at Docker container startup.
Given a file test.file:
My File with an ${env.ENV_VAR}
And a variable set in the shell:
export ENV_VAR='environment variable'
You could run:
envreplace test.file
And test.file would be changed to:
My File with an environment variable
npm install -g envreplace
- Supports specifying your own format for the regular expression that finds env var matches
- Allows use of node.js file globbing
- Verbose mode that logs all replacements
- Option to fail on missing variables
