.templateto the filename passed as argumentt - transforms that file using
process.envas the context - saves the result to the original name supplied on the command line
-t, --templatePath the path to the template file
-h, --help show help
-v, --version current version
venv process --templatePath assets\env.js
assets\env.js.template:
(function (window) {
window.__env = window.__env || {};
window.__env.BUILD_BUILDNUMBER = '<%= env.BUILD_BUILDNUMBER %>';
}(this));<html>
