node-red-contrib-mockingbird 0.1.0

A Node-RED node to create a mockdata for test-cases.

npm install node-red-contrib-mockingbird

base on node-red-node-web-data-generator

A Node-RED node to create a mockdata for test-cases.

Install

Run the following command in your Node-RED user directory - typically ~/.node-red

    npm install node-red-contrib-mockingbird

Usage

Creates dummy data based on a handlebars-style template.

Uses the dummy-json module, which can create rich sets of dummy data for testing or other uses.

It will build a string, or a parsed JSON object, creating values based on the helper names below:

title, firstname, lastname, company, domain, tld, email,
street, city, country, countryCode, zipcode, postcode,
lat, long, phone, color, hexColor, guid,
ipv4, ipv6, lorem, date, time,
lowercase, uppercase, int, float, boolean

Multiple values can be generated by use of the repeat syntax.

In addition any properties passed in on the msg object can also be used - for example {{payload}}.

Finally msg.seed can be used to preset the pseudo-random seed to ensure repeatability across calls.

Example

The example flow below produces a JSON string which is then converted into an object, for example:

{
    "name": "Theo Cumbie",
    "work": "CoreXTS",
    "email": "[email protected]",
    "address": "83 Sherman Road",
    "country": "Angola",
    "text": "Sagittis orci elementum e vel scelerisque. Amet ac tristique lectus. Morbi e suscipit scelerisque auctor curabitur velit metus gravida quis."
}
