# fmtprodmsgFactory

> Return a `function` which formats an error message for production.

<section class="usage">

## Usage

```javascript
var fmtprodmsgFactory = require( '@stdlib/error/tools/fmtprodmsg-factory' );
```

#### fmtprodmsgFactory( \[options] )

Returns a `function` which formats an error message for production.

```javascript
var opts = {};
var fcn = fmtprodmsgFactory( opts );
// returns <Function>

var msg = fcn( '3' );
// returns 'Minified stdlib error code: 3. Visit https://stdlib.io/docs/api/latest/error-decoder.html?code=3 for the full message.'
```

The function accepts the following `options`:

-   **url**: website URL for full error message.
-   **message**: error message template with `{{url}}` and `{{code}}` placeholders that will be replaced.

To set a custom URL, use the `url` option:

```javascript
var opts = {
    'url': 'https://stdlib.io/error-decoder.html'
};

var fcn = fmtprodmsgFactory( opts );
// returns <Function>

var msg = fcn( '8' );
// returns 'Minified stdlib error code: 8. Visit https://stdlib.io/error-decoder.html?code=8 for the full message.'
```

To change the error message template, use the `message` option:

```javascript
var opts = {
    'message': 'Error code: {{code}}. See: {{url}}.'
};

var fcn = fmtprodmsgFactory( opts );
// returns <Function>

var msg = fcn( '27', 'foo', 'bar' );
// returns 'Error code: 27. See: https://stdlib.io/docs/api/latest/error-decoder.html?code=27&arg[]=foo&arg[]=bar.'
```
