rpbouman/huey

Description and use

**Brief summary**
Huey (rpbouman/huey) is a lightweight, browser‑based library that builds ROLAP pivot tables on top of DuckDB‑WASM, letting users turn raw CSV/JSON data into searchable, drill‑down analytics without a server component. It is geared toward fast prototyping of data‑exploration and reporting pipelines, especially when you need an in‑browser SQL engine and interactive pivot UI.

**Value**

• **Instant analytics** – By bundling DuckDB compiled to WebAssembly, Huey runs full SQL queries locally, so data never leaves the client and latency is near‑zero.
• **Low‑code pivoting** – The built‑in pivot table UI lets non‑technical users slice, dice, and filter datasets with a few clicks, accelerating exploratory analysis and reducing the need for separate BI tools.
• **Extensible pipeline** – Because the output is plain JavaScript objects, you can pipe results into downstream automation, dashboards, or export routines, making Huey a convenient glue layer between raw data ingestion and reporting.

**Practical adoption path**

1. **Proof‑of‑concept** – Clone the repo, run the demo page, and feed a small sample dataset (CSV/JSON) to verify the pivot UI and SQL capabilities.
2. **Integration** – Wrap Huey’s API in a thin module inside your existing front‑end stack (React, Vue, etc.), and replace the demo data source with your own data loader (e.g., fetch from an S3 bucket or a local file input).
3. **Validation** – Write a few unit tests around the data‑load and pivot configuration to ensure the library behaves as expected with your schema.
4. **Scale‑up** – If the use case grows beyond browser‑only workloads, consider a hybrid approach where heavy preprocessing runs server‑side and only the final summarized tables are handed to Huey for interactive exploration.

**Production readiness**
Huey sits at a **medium** readiness level: it is mature enough (571 ★, recent updates, JavaScript core) for internal tools, prototypes, and low‑traffic dashboards, but it still requires due diligence before mission‑critical deployment. Key checks include: verifying the DuckDB‑WASM bundle size fits your bandwidth constraints, confirming that the pivot UI meets accessibility and security standards, and establishing a maintenance plan for the underlying dependencies (DuckDB, WebAssembly runtime). Once those items are addressed, Huey can be promoted to production for internal analytics pipelines, while external‑facing services should undergo additional load and security testing.

Use in a workflow
