yandex/clickhouse-server:20.3.21.2 none of these work:

stream = clickHouseCliento.query('SELECT 1', { format: 'CSV' })
// makes RecordStream with format CSV
stream.on('data',console.log).on('end',()=>console.log('end'))
// console output: end

stream = clickHouseCliento.query('SELECT 1 FORMAT CSV', {})
// makes RecordStream with format JSONCompact
stream.on('data',console.log).on('end',()=>console.log('end'))
// console output: end

stream = clickHouseCliento.query('SELECT 1 FORMAT CSV', {omitFormat:true})
// makes RecordStream with format JSONCompact
stream.on('data',console.log).on('end',()=>console.log('end'))
// console output: end

stream = clickHouseCliento.query('SELECT 1 FORMAT CSV', {omitFormat:true,readonly:true})
// makes RecordStream with format JSONCompact
stream.on('data',console.log).on('end',()=>console.log('end'))
// console output: end

Only JSON streams are working:

clickHouseCliento.query('SELECT 1').on('data',console.log).on('end',()=>console.log('end'))
// [ 1 ]\n end

CURL confirms the sanity:

$ echo 'SELECT 1 FORMAT CSVWithNames' | curl 'http://localhost:8123/' --data-binary @-
