Uncaught Error: Dynamic require of "events" is not supported
Going through the Hyperdrive Mysql guide and hitting this error consistently. I've got nodejs_compat and compat date set according to the guide(although different guides use different compat dates, I've tried both).
Still hitting the error.
wrangler.staging.toml:
---------------------
name = "[REDACTED]-staging"
main = "dist/worker.bundle.js"
compatibility_date = "2024-08-21"
compatibility_flags = ["nodejs_compat"]
[vars]
ENVIRONMENT = "staging"
[observability.logs]
enabled = true
invocation_logs = false
[[hyperdrive]]
binding = "HYPERDRIVE"
id = "[REDACTED]"
=========================================
database.js:
----------------
import { createConnection } from "mysql2/promise";
export async function getDomainSettings(domain, env) {
const connection = await createConnection({
host: env.HYPERDRIVE.host,
user: env.HYPERDRIVE.user,
password: env.HYPERDRIVE.password,
database: env.HYPERDRIVE.database,
port: env.HYPERDRIVE.port,
// The following line is needed for mysql2 compatibility with Workers
// mysql2 uses eval() to optimize result parsing for rows with > 100 columns
// Configure mysql2 to use static parsing instead of eval() parsing with disableEval
disableEval: true,
});
try {
// Sample query
const [results, fields] = await connection.query("SHOW tables;");
// Clean up the client after the response is returned, before the Worker is killed
ctx.waitUntil(connection.end());
return results;
} catch (e) {
console.error(e);
}
}
Still hitting the error.
