In @content/200-orm/050-overview/500-databases/400-mysql.mdx:
- Line 80: The code wraps process.env.DATABASE_URL in a template literal which
turns undefined into the string "undefined" and causes confusing parsing errors;
replace the template usage by reading the env var directly (const
connectionString = process.env.DATABASE_URL) and add an explicit check that
throws or logs a clear error if connectionString is missing (e.g., if
(!connectionString) throw new Error("DATABASE_URL environment variable not
set")) so failures report the missing env var rather than a malformed
"undefined" connection string.
- Line 82: The code calls new PrismaMariaDb(connectionString) but PrismaMariaDb
expects an options/config object (e.g., host, port, user, password, database,
connectionLimit) rather than a plain connection string; replace the
connectionString argument with an object literal containing those properties
when instantiating PrismaMariaDb (reference: PrismaMariaDb constructor).
