# @nota/env-in-template

Simple script to inject variables from shell ENV into a file.

Useful when building a multistage docker image.

## Usage:

env-in-template INPUT_FILE OUTPUT_FILE

**Example:**

Input file "input.json-tmpl" with this content:

```

{

  <% if (typeof ssl !== 'undefined' && ssl) {

    %>

    "SSL": <% print(JSON.stringify(ssl)) %>,

    <%

  }

  %>

  "PATH": "<%= PATH %>"

}

```

Run:

```bash

env-in-template input.json-tmpl output.json

```

Creates "output.json" with this content:

```javascript

{

  "PATH": "/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin"

}

```

Adding `ssl` to the environment variables:

```bash

ssl=1 env-in-template input.json-tmpl output.json

```

Will create "output.json" with this content:

```javascript

{

    "SSL": "1",

  "PATH": "/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin"

}

```
