obind

Partial application for functions taking a single argument object.

NPM

Build status dependencies devdependencies semantic-release manpm

Install and use under Node: npm install obind --save

Use: obind(fn, partialOptions), returns new function.

Example

var obind = require('obind');
function foo(options) { ... }
var withBar = obind(foo, { bar: 'bar' });
withBar({ baz: 'baz' });
/*
equivalent to
foo({
    bar: 'bar',
    baz: 'baz'
})
*/

It is like Function.prototype.bind but for function that expect single options object. Note, obind only does partial application, not context binding.

See Partial application for options object blog post.

For more examples, see this page.

In the browser include the script and then use window.obind function.

Additional arguments after the first object will be passed unchanged

function foo(options, a, b) { ... }
var bound = obind(foo, someOptions)
bound(moreOptions, a, b)
// same as
foo(moreOptions + someOptions, a, b)
