Longo

SupportedMongoShellAPIs

This matrix is not well maintenanced yet.

Longo is focusing to be work as like as Mongo Shell in browser world.

Mongo Shell APIs described below are supported.

Except non-CRUD operation like Sharding, Replication, Auth, etcetra are not supported because it is used only in the browser by single user.

Query operators

Query operators are depended on underscore-query.

Query API $equal $contains $ne $lt $lte $gt $gte $between $in $nin $all $any $size $exists or $has $like $likeI $elemMatch

$regex $cb $computed

Longo does not support $regex、$cb、$computed operators. Because we use JSON formatted message between main thread and worker thread.

You can use Longo.collection.find({}).map instead, to perform like $regex、$cb、$computed operators.

Projection operators
