Installation and usage

Connect to the database or file and compress the data. Here is an example on how to create API endpoint that returns data from MongoDB:

const compressor = require('flexmonster-compressor');
const MongoClient = require('mongodb').MongoClient;
 
MongoClient.connect("mongodb://demo:p123456@ds121251.mlab.com:21251/flexmonster", { useNewUrlParser: true }, (err, client) => {
    if (err) throw err;
    console.log("Connected successfully to MongoDB.");
    app.set("db", client.db("flexmonster"));
});
 
app.get('/mongodb', (req, res) => {
    const db = req.app.get('db');
    const result = db.collection('sample_data').find({}, { projection: { '_id': false } }).stream();
    let stream = compressor.compressJsonStream(result);
    stream.on('data', data => res.write(data));
    stream.on('end', () => res.end());
});

To get the data on the front-end, please use the following code:
