I am using Knex.js for database connections. I would like to use a connection string instead of the connection object for connecting to a database and be able to specify the charset.
Example:
connection: 'mysql://root:[email protected]:3306/test-db'
NOT
connection: {
host : '127.0.0.1',
user : 'root',
password : 'secret',
database : 'test-db',
charset : 'utf8'
}
I have the connection string working.
Could someone explain how I would specify the charset in the Knex.js connection string?

Knex is a technique that is used to build queries. It supports various databases like Postgres, MySQL, SQLite, Oracle, and some others as well. It provides both callbacks and promise interface. It provides connection pooling and standardized responses. It is an efficient tool for node.
Sequelize is an ORM that includes some query builder stuff; Knex is just a query builder, not an ORM.
The knex. schema is a getter function, which returns a stateful object containing the query. Therefore be sure to obtain a new instance of the knex. schema for every query.
Connecting Knex with Postgres We specify the connection parameters for Postgres and point Knex to connect to the pg client. const db = require("knex")({ client: "pg", connection: { host: "localhost", user: "postgres", password: "", database: "knex-test" } }); app. set("db", db);
Try:
connection: 'mysql://root:[email protected]:3306/test-db?charset=utf8mb4'
See connection string options as described here: https://github.com/mysqljs/mysql#connection-options
