mongosh shine cikakken JavaScript REPL — kana iya amfani da JS masu sa'a, loops, da ayyuka tare da umarni na bankasuwa.
// CRUD operations (the db object refers to the current database)
db.users.insertOne({ name: "Ann" });
db.users.find({ age: { $gt: 25 } });
db.users.find().pretty(); // pretty-print results (readable)
db.users.updateOne({ name: "Ann" }, { $set: { age: 31 } });
db.users.countDocuments({ active: true });
Ka gudu ayyukan CRUD da aggregation gida kamar kodin aikace-aikace, amfani da db.collection.method() syntax.
db.users.stats(); // collection statistics
db.users.getIndexes(); // list indexes on a collection
db.users.createIndex({ email: 1 }); // create an index
db.users.explain().find({ ... }); // see the query plan (performance)
db.stats(); // database statistics
db.serverStatus(); // server info
mongosh kana da mahimmanci ga kula dashi — ƙirƙira indexes, dubawar lissafi, dubawar shawwara na bugun jiya (explain don sauri), da kula da bankasuwa.
// use JavaScript for scripting/bulk operations
