Node Expansion

Module for expanding terms to children.

Install

npm i @biothings-explorer/node-expansion

Usage

• by default, the module will expand terms to all descendants

const { getDescendants } = require('@biothings-explorer/node-expansion');

console.log(getDescendants(['GO:0022010', 'DOID:0060524']));

// {
//   'DOID:0060524': [
//     'DOID:0040001',
//     'DOID:0060526',
//     'DOID:0060525',
//     'DOID:0060527',
//     'DOID:0060528',
//     'DOID:0060529'
//   ]
// }

• use recursive=false to get direct children only

const { getDescendants } = require('@biothings-explorer/node-expansion');

console.log(getDescendants(['GO:0022010', 'DOID:0060524', 'DOID:4'], recursive=false));

// {
//   'DOID:0060524': [ 'DOID:0040001', 'DOID:0060526' ],
//   'DOID:4': [
//     'DOID:0014667',
//     'DOID:0050117',
//     'DOID:0080015',
//     'DOID:14566',
//     'DOID:150',
//     'DOID:225',
//     'DOID:630',
//     'DOID:7'
//   ]
// }
