Requires:
>= 1.0.0(thepathnameconfig option and URL-based configuration were introduced in 1.0.0). For< 1.0.0, a partial fix for pathname handling in the parameter was shipped in .
host0.2.5Symptom: Wrong database is selected, or requests fail when ClickHouse is behind a proxy with a path prefix (e.g., http://proxy:8123/clickhouse_server).
Cause: Passing the pathname in url makes the client treat it as the database name.
Fix: Use the pathname option separately:
import { createClient } from "@clickhouse/client";
const client = createClient({
url: "http://proxy:8123",
pathname: "/clickhouse_server", // leading slash optional; multiple segments supported
});For proxies that require custom auth headers:
Requires:
>= 1.0.0(http_headersconfig option; replaces the deprecatedadditional_headersfrom>= 0.2.9). Per-requesthttp_headersoverrides are available since>= 1.11.0.
import { createClient } from "@clickhouse/client";
const client = createClient({
http_headers: {
"My-Auth-Header": "secret",
},
});
