  birthday: Schema.Date
})

const program = Effect.gen(function*() {
  const client = yield* MongoClient.connectScoped("mongodb://localhost:27017")
  const db = MongoClient.db(client, "source-db")
  const sourceCollection = Db.collection(db, "source", Person)
  const destinationCollection = Db.collection(db, "destination", Person)

  const items = yield* Collection.find(sourceCollection).pipe(FindCursor.toArray)

  yield* Collection.insertMany(destinationCollection, items)
})

await program.pipe(Effect.scoped, Effect.runPromise)

Documentation

effect-mongodb is the core package that provides effectful APIs to work with MongoDB.

MongoDB driver compatibility

We adhere to the MongoDB driver compatibility guidelines, so minor releases might break compatibility with older MongoDB servers.

For example, upgrading the Node.js driver from 6.8 to 6.10 will make it incompatible with MongoDB server 3.6.

Roadmap

• @effect-mongodb/services package to provide Effect services/layers to use with effect-mongodb
