MySQL error – ..but as of v2.0 you must provide streamFactory option returning ReadStream – How to fix?

In this post we will take a look at how to resolve the MySQL error – Error: As a result of LOCAL INFILE command server wants to read emp.csv file, but as of v2.0 you must provide streamFactory option returning ReadStream.

This error occurs when you import a CSV file to a table in MySQL / MariaDB. To read files from the filesystem, since mysql2 we have to explicitly specific the infileStreamFactory when we create a new connection.

const conn = mysql.createConnection({
  //..
  //..
  infileStreamFactory: path => fs.createReadStream(path)
})

The MySQL client that you have been using should also be updated to read files from your local system.
