Because Valkey uses the same protocol as Redis, any Redis client is compatible. You can use this example with the official node-redis client:
import { createClient, SCHEMA_FIELD_TYPE } from 'redis';
const client = createClient({ url: process.env.STACKHERO_VALKEY_URL_TLS });
await client.connect();
// Create the index once at startup
try {
await client.ft.create(
'productsIndex',
{
name: SCHEMA_FIELD_TYPE.TEXT,
brand: SCHEMA_FIELD_TYPE.TAG,
price: SCHEMA_FIELD_TYPE.NUMERIC
},
{ ON: 'HASH', PREFIX: 'product:' }
);
} catch (error) {
if (!error.message.includes('Index already exists')) {
throw error;
}
}
await client.hSet('product:1', { name: 'Espresso machine', brand: 'Bianca', price: '459' });
const results = await client.ft.search('productsIndex', '@brand:{Bianca} @price:[0 500]');
console.log(results.total, results.documents);
await client.quit();
