# mongodb-build-info

Helpful functions to figure out if a connection is on Atlas, Atlas Data Lake,
Enterpise, or DocumentDB/CosmosDB.

# Usage

```js
const getBuildInfo = require('mongodb-build-info');
const MongoClient = require('mongodb').MongoClient;

MongoClient.connect('localhost:27017', function (err, client) {
  const adminDB = client.db('test').admin();
  let buildInfo;

  adminDB.command({ buildInfo: 1 }, {}, parseBuildInfo);
  adminDB.command({ getCmdLineOpts: 1 }, {}, parseCmdLineOpts);

  function parseBuildInfo(err, res) {
    if (err) console.log('Command failed, ', err);
    buildInfo = res;

    const { isDataLake, dlVersion } = getBuildInfo.getDataLake(buildInfo);
    const isEnterprise = getBuildInfo.isEnterprise(buildInfo);
  }

  function parseCmdLineOpts(err, res) {
    if (err) console.log('Command failed', err.message);

    const { isGenuine, serverName } = getGenuineMongoDB(buildInfo, res);
  }
});
```
