njk is a single binary command line application designed to provide powerful templating capabilities using environment variables.
Its primary use is to build configuration files at boot time in containerized environments.
njk stands on shoulders of giants. It uses Nunjucks as the templating engine and QuickJS as the runtime. The result is a statically linked binary which is < 1MB.
NOTE: Windows is not currently supported.
./njk /path/to/template-file.njk > /config/your-config-fileExample:
Hello, {{ env.USER }}
Check the Nunjucks documentation on templating.
NOTE: Templates get a single context variable: env containing the environment
variables.
