Notable Changes

  • CONJS-148 - permit setting socket keep alive (option `keepAliveDelay`)

  • CONJS-133 - Support ES2020 BigInt object (option `supportBigInt`)

keepAliveDelaypermit to enable socket keep alive, setting delay. 0 means not enabled. Keep in mind that this don't reset server @@wait_timeout (use pool option idleTimeout for that). in ms*int*

CONJS-143 is a breaking change. Queries that have a IN parameter with array parameters format change. previous format did not accept parenthesis :

conn.query('SELECT * FROM arrayParam WHERE id = ? AND val IN ?', [1, ['b', 'c']]);

now, format is

conn.query('SELECT * FROM arrayParam WHERE id = ? AND val IN (?)', [1, ['b', 'c']]);

same than mysql/mysql2 drivers. previous behaviour can be reverted setting option `arrayParenthesis` to true.

Bugs Fixed

  • CONJS-145 - batch rewrite error when packet reach maxAllowedPacket
  • CONJS-146 - Using callback API, batch, avoid return error if connection not established
  • CONJS-144 - TypeScript type ssl wrong definitions
