# print env via NJS

consult [Dockerfile](Dockerfile) or [docker-compose.yml](docker-compose.yml) - both are simple and fine enough.

configuration:

```nginx
server {
    listen 8080;

    location / { return 204; }

    js_import ngx_env.js;
    location = /env
    {
        js_content ngx_env.report;
    }
}
```

---

NJS script:

```js
function report(r) {
    var s = "";
    const keys = Object.keys(process.env).sort();
    for (const i in keys) {
        const k = keys[i];
        const v = process.env[k];
        s += k + '=' + v + "\n";
    }
    r.return(200, s);
}

export default { report };
```

Test URI e.g. with `curl`:
```sh
curl http://127.0.0.1:8080/env
```
