I'm new to Yii2.

I want to use MongoDB with Yii2-advanced. For that, I have found this library:

https://github.com/yiisoft/yii2-mongodb

The issue is it doesn't explain much about the installation and configurations.

As the read me says I have added following into the common\config\main-local.php file:

'mongodb' => [
  'class' => '\yii\mongodb\Connection',
  'dsn' => 'mongodb://developer:password@localhost:27017/mydatabase',
 ],

But what should I do with the default db key which is there for of the MySQL connection:

'db' => [
  'class' => 'yii\db\Connection',
  'dsn' => 'mysql:host=localhost;dbname=yii2_advanced_mongo',
  'username' => 'root',
  'password' => 'root',
  'charset' => 'utf8',
],

If I comment out that db key and try to login, then it gives me following error:

Invalid Configuration – yii\base\InvalidConfigException

Unknown component ID: db

I think you should add the entry properly, if you want use the entry db for accessing your db datas you should comment the db entry related to mysql and assign db to your mongodb entry 

'db' => [
  'class' => '\yii\mongodb\Connection',
  'dsn' => 'mongodb://your_user_name:your_password@localhost:27017/your_database',
],

//'db' => [
//   'class' => 'yii\db\Connection',
//   'dsn' => 'mysql:host=localhost;dbname=yii2_advanced_mongo',
//   'username' => 'root',
//   'password' => 'root',
//   'charset' => 'utf8',
//],
