如何将 JavaScript 日期转换为 PostgreSQL 时间（无时区）？

Question

I use knex with PosgreSQL . I have a table with a Time column.

After trying to insert data in the table, knex throws an error with the following message:

...invalid input syntax for type time: \"2021-07-21T14:40:00.000+03:00\..."

Code example

await knex('table_name')
 .insert({ id: 1, time: new Date() })

What is a correct way to preserve JavaScript Date object as a PosgreSQL Time? Should I use 3rd party libs? Or it can be done using knex only?

Answer 1

I was able to fix this issue by manually converting the JavaScript Date object into one of the supported formats of the PostgreSQL.

The 8.5.1.1. Dates 8.5.1.1. Dates and 8.5.1.2. Times 8.5.1.2. Times chapters have a full list of supported types.

My solution was to use date-fns/format (eg format(new Date(), 'HH:mm') // 14:00 )

PS I'm not sure if this approach is right but it works.
