gw_dsl_parser: Convert your graphic-walker workflow to sql
Decision gist · record as of 2026-08-14
Yes, if you are building on graphic-walker and need to translate visual workflows to SQL. The package has low install friction and permissive licensing. However, maintenance is dormant (last release 2024-07-31), so verify that the DSL subset and SQL generation match your use case before committing to a dependency on it.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- wasmtime runtime dependency must be available; verify wasm module is downloaded via scripts/download_wasm.py if not automatic
- Low install friction with a single runtime dependency (wasmtime).
- Package is dormant—last release was over a year ago with no recent commits, though the repository remains active and unarchived.

What it is and what it does
gw-dsl-parser converts graphic-walker workflow definitions—JSON payloads describing visual query operations like aggregations and grouping—into SQL statements executable against a database table. It bridges the gap between visual query builders and SQL databases by translating declarative workflow objects into standard SQL.
The package wraps a WebAssembly module (via wasmtime) to perform the DSL parsing. You provide a workflow payload, a table name, and the package returns the corresponding SQL string. It's designed as a backend utility for tools that let users build queries visually and need to execute them as SQL.
Use it for
- Export visual queries built in graphic-walker as executable SQL for database execution
- Build a backend API that converts user-drawn query workflows into SQL without exposing raw SQL to the frontend
- Generate SQL from workflow definitions stored in JSON for batch processing or audit logging
- Integrate visual query builders into data applications that require SQL-based query execution
