Venv uses [EJS](https://ejs.co) to transform a template file using Node's `process.env` map. ## CLI Usage Usage: `venv [options]` Your build or deploy pipeline could include ``` npm install venv -g venv process -t src\environments\environment.prod.ts ``` ### Commands: ### process - appends `.template` to the filename passed as argument `t` - transforms that file using `process.env` as the context - saves the result to the original name supplied on the command line ### Options: ``` -t, --templatePath the path to the template file -h, --help show help -v, --version current version ``` #### Example > venv process --templatePath assets\env.js __assets\env.js.template__: ```javascript (function (window) { window.__env = window.__env || {}; window.__env.BUILD_BUILDNUMBER = '<%= env.BUILD_BUILDNUMBER %>'; }(this)); ``` ```html ``` ## Exit Codes The CLI process may exit with the following codes: - `0`: Transform succeeded without errors - `1`: An invalid command line argument or combination thereof was used - `2`: Transform failed --- _Source: https://npm.io/package/venv · Machine-readable twin of the npm.io package page.
