Compromise

I've given up my slot on npm to the more popular nlp_compromise. If you need this for your project the old versions will remain at <=0.1.1.

Allows composition of functions that require a callback. Assumes the callbacks are node style e.g.,:

function (err, data) {
    // Do stuff
}

Usage

Takes a context and series of methods to call on the context. Passes the data portion of the previous callback to the next, thus creating a crude pipeline. For example:

var example = {
    // Notice that get will always receive the signature of the preceding method in the chain
    get: function get(url, methods, callback) {
        callback(null, url, {name: 'foo', age: 42});
    },

    options: function options(url, callback) {
        callback(null, url, {methods: ['get', 'post']});
    },

    post: function post(url, data, callback) {
        callback(null, {success: true});
    }
};

compromise(target, 'options', 'get', 'post')('/foo').then(function (resp) {
    resp.success; // true
});
