Simple API for managing options in JavaScript applications.
Install with npm:
$ npm install --save option-cacheUse options-cache in your javascript application:
var util = require('util');
var Options = require('options-cache');
function App(options) {
Options.call(this, options);
this.init();
}
util.inherits(App, Options);
App.prototype.init = function() {
this.option('cwd', process.cwd());
this.option('foo', 'bar');
};
App.prototype.a = function(value) {
this.enable(value);
};
App.prototype.b = function(value) {
if (this.enabled(value)) {
// do something
} else {
// do something else
}
};Create a new instance of Options.
Params
options{Object}: Initialize with default options.
Example
var app = new Options();Set or get a default value. Defaults are cached on the .defaults object.
Params
key{String}: The option name.value{any}: The value to set.returns{any}: Returns avaluewhen onlykeyis defined.
Example
app.default('admin', false);
app.default('admin');
//=> false
app.option('admin');
//=> false
app.option('admin', true);
app.option('admin');
//=> trueSet or get an option.
Params
key{String}: The option name.value{any}: The value to set.returns{any}: Returns avaluewhen onlykeyis defined.
Example
app.option('a', true);
app.option('a');
//=> trueParams
key{String}value{any}type{String}: Javascript native type (optional)returns{Object}
Example
app.option('admin', true);
console.log(app.either('admin', false));
//=> true
console.log(app.either('collaborator', false));
//=> falseParams
key{String}value{any}type{String}: Javascript native type (optional)returns{Object}
Example
app.option('a', 'b');
app.fillin('a', 'z');
app.fillin('x', 'y');
app.option('a');
//=> 'b'
app.option('x');
//=> 'y'Return true if options.hasOwnProperty(key)
Params
prop{String}returns{Boolean}: True ifpropexists.
Example
app.hasOption('a');
//=> false
app.option('a', 'b');
app.hasOption('a');
//=> trueEnable key.
Params
key{String}returns{Object}Options: to enable chaining
Example
app.enable('a');Disable key.
Params
key{String}: The option to disable.returns{Object}Options: to enable chaining
Example
app.disable('a');Check if prop is enabled (truthy).
Params
prop{String}returns{Boolean}
Example
app.enabled('a');
//=> false
app.enable('a');
app.enabled('a');
//=> trueCheck if prop is disabled (falsey).
Params
prop{String}returns{Boolean}: Returns true ifpropis disabled.
Example
app.disabled('a');
//=> true
app.enable('a');
app.disabled('a');
//=> falseReturns true if the value of prop is strictly true.
Params
prop{String}returns{Boolean}: Uses strict equality for comparison.
Example
app.option('a', 'b');
app.isTrue('a');
//=> false
app.option('c', true);
app.isTrue('c');
//=> true
app.option({a: {b: {c: true}}});
app.isTrue('a.b.c');
//=> trueReturns true if the value of key is strictly false.
Params
prop{String}returns{Boolean}: Uses strict equality for comparison.
Example
app.option('a', null);
app.isFalse('a');
//=> false
app.option('c', false);
app.isFalse('c');
//=> true
app.option({a: {b: {c: false}}});
app.isFalse('a.b.c');
//=> trueReturn true if the value of key is either true or false.
Params
key{String}returns{Boolean}: True iftrueorfalse.
Example
app.option('a', 'b');
app.isBoolean('a');
//=> false
app.option('c', true);
app.isBoolean('c');
//=> trueBreaking changes
