module

mongodb

MongoDB through your own API route. Atlas retired its HTTP Data API (September 2025), and a database password must never reach the browser, so the browser sends Commands to a server route (generated by weft add mongodb), which checks them against a Policy and runs them with the official driver.

let db = Mongo::new("/api/mongo");
let req = db.find("products", json!({ "tags": "lamp" })).sort(json!({ "price": 1 })).limit(12).request();
let docs = mongodb::parse_documents(&weft::web::fetch(req).await?)?;

Structs

  • Mongo

  • Policy

    Which collections the browser may use, and how.

Enums

  • Access
