import ezbase from 'ezbase'
const eb = new ezbase("http://0.0.0.0:3690"); 
...
eb.db.createCollection("example-collection");

Deletes an existing collection.

import ezbase from 'ezbase'
const eb = new ezbase("http://0.0.0.0:3690"); 
...
eb.db.deleteCollection("example-collection");

Get Collections' Names

const getCollections = async (id) => {
    try {
        // get the collections' names from the database
        const collections = await eb.db.getCollectionNames();

        // create the document from the database
        const docIndex = await eb.db.insertSingleFieldDoc("newcol1", {"name": "Lorem Ipsum"});
