fmtprodmsgFactory

Return a function which formats an error message for production.

Installation

npm install @stdlib/error-tools-fmtprodmsg-factory

Usage

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

fmtprodmsgFactory( [options] )

Returns a function which formats an error message for production.

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:

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:

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.'

Examples

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

var formatProdErrorMessage = fmtprodmsgFactory();
var msg = formatProdErrorMessage( '3', 'foo' );
// returns 'Minified stdlib error code: 3. Visit https://stdlib.io/docs/api/latest/error-decoder.html?code=3&arg[]=foo for the full message.'

msg = formatProdErrorMessage( '5', 'foo', 'bar' );
// returns 'Minified stdlib error code: 5. Visit https://stdlib.io/docs/api/latest/error-decoder.html?code=5&arg[]=foo&arg[]=bar for the full message.'

msg = formatProdErrorMessage( '5', 'foo', 'bar', 123 );
// returns 'Minified stdlib error code: 5. Visit https://stdlib.io/docs/api/latest/error-decoder.html?code=5&arg[]=foo&arg[]=bar&arg[]=123 for the full message.'
