data-seed

Fake data generator for js develop.

Install

npm install data-seed

Usage

const {util, seed} = require('data-seed');

// specific seed or util
const {
    util: {
        random
    },
    seed: {
        ip4
    }
} = require('data-seed');

seed.ip4(); // 23.4.126.0
ip4(); // 1.1.1.123

Utils

util.deep

util.deep accepts a callback function which will return data.

The callback function accepts 4 arguments:

• DEEP: identify data loop
• DONE: return DONE will stop loop
• level: record the deep level of data
• isFirst: whether first data

Create a tree nodes:

const {util: {deep}} = require('data-seed');

let data = deep((DEEP, DONE, level, isFirst) => {
    return level < 2 ? {
        name: 'lxjwlt',
        nodes: DEEP
    } : DONE;
});

/*
    data:
    {
        name: 'lxjwlt',
        nodes: {
            name: 'lxjwlt'
        }
    }
*/
