node-red-node-web-data-generator
|
|
================================
|
|
|
|
A <a href="http://nodered.org" target="_new">Node-RED</a> node to create dummy
|
|
data values from a template. Useful for building test-cases.
|
|
|
|
Install
|
|
-------
|
|
|
|
Either use the Manage Palette option in the Node-RED Editor menu, or run the following command in your Node-RED user directory - typically `~/.node-red`
|
|
|
|
npm i node-red-node-data-generator
|
|
|
|
Usage
|
|
-----
|
|
|
|
Creates dummy data based on a handlebars-style template.
|
|
|
|
Uses the <i><a href="https://github.com/webroo/dummy-json/blob/master/README.md" target="_new">dummy-json</a></i>
|
|
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 "+xx (x) xxxx xxx xxx", color, hexColor, guid,
|
|
ipv4, ipv6, lorem nn, date, time,
|
|
lowercase (helper), uppercase (helper), 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": "theo.cumbie@corexts.gov",
|
|
"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."
|
|
}
|
|
|
|
