Installation & Quickstart

Using AVA through an AI agent? Start with the Agent Skill guide. This quickstart covers the TypeScript / JavaScript SDK.

Install

Use Node.js 22.13.0 or later , as required by the package. Install AVA 4.0.0 with your preferred package manager:

npm install @antv/ava@4
# or
pnpm add @antv/ava@4
# or
yarn add @antv/ava@4

Configure your model

The example below reads OPENAI_API_KEY and optional OPENAI_MODEL / OPENAI_BASE_URL from your process environment. Set these before running it. AVA also accepts a preconfigured AI SDK model; see model configuration.

Run your first analysis

This complete Node.js example uses the default DuckDB engine. Save it as an ES module in a project with @antv/ava installed.

import { AVA } from '@antv/ava';
 
const ava = new AVA({
  llm: {
    model: process.env.OPENAI_MODEL || 'gpt-4o-mini',
    apiKey: process.env.OPENAI_API_KEY,
    baseURL: process.env.OPENAI_BASE_URL,
  },
});
 
try {
  await ava.source({
    type: 'json',
    options: {
      data: [
        { region: 'East', revenue: 120 },
        { region: 'West', revenue: 90 },
        { region: 'East', revenue: 80 },
      ],
    },
  });
 
  const schema = await ava.schema();
  const profile = await ava.profile();
  console.log(schema.models, profile.models[0].metrics);
 
  const result = await ava.analyze('Show total revenue by region');
  console.log(result.text, result.data);
 
  const chart = await ava.visualize(result);
  if (chart) console.log(chart.config);
} finally {
  await ava.dispose();
}

Cleanup and errors

source() replaces the current dataset and releases the previous engine. dispose() releases connections and engine resources and clears the schema and cached profile. Always await cleanup, including after a failed analysis.

Next steps

• Data sources — connect files, inline data, and databases.
• Inspect your data — inspect structure and compute statistics.
• Define data semantics — write business rules and reusable measures, with a worked sales example.
• Browser usage — use the frontend entry point.
• CLI — work from your terminal.

See the API Reference for every method and its input parameters.
