MongoDB

MongoDB is a first-class engine in fordb — a full document surface, not a read-only preview. Connect with discrete fields or a connection URI (the two stay in sync, like the Postgres form), and the schema tree lists databases → collections.

Query documents

A collection opens a document tab with three modes:

• find — a relaxed-JSON filter ({ status: "open" }); results page as you scroll.
• aggregate — a JSON pipeline array ([{ "$match": … }, { "$group": … }]).
• bulk — see below.

Explain any find or aggregate to see the query plan (executionStats), and Export the full result to JSON or NDJSON (mongoexport's line-per-document format).

Edit documents

Insert, edit, and delete documents by _id directly from the result cards — each change is a single-document write. Extended-JSON types (ObjectId, dates) round-trip losslessly.

Bulk writes

Bulk mode takes a filter plus an operation:

• updateMany — apply an update document (e.g. { "$set": { "archived": true } }) to every match.
• deleteMany — delete every match.

Preview count shows how many documents match before you commit, and Apply confirms with that count — with a loud warning if a deleteMany filter is empty (a whole-collection wipe).

Collection & index admin

Right-click a collection or its database:

• Indexes… — list a collection's indexes and create (compound + unique) or drop them.
• Validation… — view, set, or clear the collection's schema-validation rule ($jsonSchema).
• Rename / Drop collection, and New collection… on the database node.

User administration

Users… on a database node lists its users and their roles, creates a user (username, password, built-in role checkboxes such as readWrite / dbAdmin), and drops one. The password is used once at creation time — it never persists and never reaches the renderer.
