Description: How to translate query results and model answers in a Databricks App with gt-node.

Data in a Databricks App, such as query results and model answers, only exists at runtime. Translate it on the server with `gt-node` before it reaches the browser.

## Before you start [#before-start]

Complete the [Quickstart](/docs/integrations/databricks/quickstart). Every example below runs inside a route under `/api`, where the Quickstart's middleware has bound the request's locale with [`withGT`](/docs/node/reference/functions/with-gt).

## Translate query results [#query-results]

Call [`tx`](/docs/node/reference/functions/tx) on each text column you show to people. Leave identifiers, numbers, and dates as they are:

```ts title="server/server.ts"
app.get('/api/products', async (_req, res) => {
  const rows = await getProducts(); // your query
  const translated = await Promise.all(
    rows.map(async (row) => ({
      ...row,
      description: await tx(row.description, {
        $context: 'Product description from the catalog table',
      }),
    }))
  );
  res.json(translated);
});
```

- `$context` tells the translation model where the text appears. Describe the source rather than the wording, such as "Column headers in a sales dashboard."
- `gt-node` caches translations, so text repeated across rows or requests is translated once while the cache entry lasts. Entries expire after a default lifetime; change it with [`cacheExpiryTime`](/docs/node/reference/config#cache-expiry).
- When the request's locale is `defaultLocale`, [`tx`](/docs/node/reference/functions/tx) returns the text unchanged.

## Translate model answers [#model-answers]

To show a model's answer in the visitor's language, translate it on the server after the model responds:

```ts title="server/server.ts"
app.get('/api/summary', async (_req, res) => {
  const answer = await summarizeSales(); // your serving endpoint or agent
  res.json({ answer: await tx(answer, { $context: 'Answer from a data assistant' }) });
});
```

For a model that writes in the visitor's language on its own, pass the locale to the model instead. Read it with [`getLocale`](/docs/node/reference/functions/get-locale).

## What to use and when [#when]

- **[`<T>`](/docs/react/reference/components/t) in `client/`:** interface text, translated at build time. Keep messages people read in the client, so the CLI translates them ahead of time.
- **[`tx`](/docs/node/reference/functions/tx) on the server:** data known only at runtime, such as query results and model answers.
