Dataform DAG

Explore your Dataform project's dependency graph as an interactive diagram, right inside VS Code. The graph is parsed locally from your .sqlx files — no dataform compile, no warehouse connection, no cloud.

Features

• See the whole graph at a glance. Every model, source, view, and assertion in your project, laid out left-to-right by dependency with a color-coded legend and a minimap for large projects.
• Jump straight to the code. Click a node to open its .sqlx file in the editor.
• Follow along as you navigate. Switch the active editor to a modeled file and its node is highlighted on the canvas.
• Live updates. Edit and save any .sqlx and the graph rebuilds automatically — no refresh.
• Fast and offline. Parses .sqlx directly, so it works even on a project that doesn't compile.

Getting started

1. Open a Dataform project folder in VS Code (one with a definitions/**/*.sqlx tree).
2. Open the Command Palette (Cmd/Ctrl + Shift + P) and run Dataform DAG: Show Graph.
3. The graph opens in a new panel. Click any node to open its file; edit and save to see it update.

Node types

The legend across the top color-codes each node by its Dataform type:

source · table · view · incremental · assertion · operations

Requirements

• VS Code 1.90.0 or newer.
• A Dataform project with a definitions/ folder of .sqlx files.

Notes

The graph is built by parsing .sqlx text directly, which is what keeps it fast and dependency-free. As a result, assertions declared inline in a model's config block are folded into that model rather than shown as separate nodes, and a ref() inside a commented-out line of SQL is still counted as a dependency. For most projects the parsed graph matches the compiled one node-for-node.
