fist-fistlabs_unit_asker

Fist plugin which provides the unit to create http requests with asker

Unit _fistlabs_unit_asker inherits from _fistlabs_unit_serial, expresses any http request in 5 steps:

• options - creating request options
• prepare - prepare request options
• request - do request
• compile - parse response
• resolve - check, validate response, then return result

Usage:

$ npm i fist-fistlabs_unit_asker

app.install('fist-fislabs_unit_asker');
app.unit({
    base: '_fistlabs_unit_asker',
    name: 'news.posts',
    options: function (track, context) {
        return {
            //  any options supported by asker
            host: 'backend.example.com',
            port: 3000,
            path: '/get-news/'
        };
    },
    resolve: function (track, context) {
        var newsList = this.__base(track, context);
        return newsList.filter(function (item) {
            return item.hidden !== true;
        });
    }
});

Tips and tricks:

By default prepare step supports path factories as paths.

app.unit({
    base: '_fistlabs_unit_asker',
    name: 'news.post',
    options: function (track, context) {
        return {
            host: 'backend.example.com',
            port: 3000,
            path: {
                build: function (vars) {
                    return util.format('/news/post/%s/', vars.postId)
                }
            },
            vars: {
                postId: context.p('postId')
            }
        };
    }
});

So you can use finger routes to create paths easier:

var Rule = require('finger/core/rule');
 
var postPath = new Rule('/news/post/<postId>/');
 
app.unit({
    base: '_fistlabs_unit_asker',
    name: 'news.post',
    options: function (track, context) {
        return {
            host: 'backend.example.com',
            port: 3000,
            path: postPath,
            vars: {
                postId: context.p('postId')
            }
        };
    }
});
