knex.js + pg specify varchar to be > 255

Question

When creating a table in knex migrations, I have indicated a col as such:

table.string("content");

It defaults to varchar 255. I would like it to be able to hold more text. How do I indicate to knex that I want this to occur?

Answer 1

You can define the col in following way to set the length of the string:

    table.string("content", 1000)

This results to:

    content         character varying(1000)

Reference: http://knexjs.org/#Schema-string

Answer 2

There is also other way to do it:

table.text(columnName, [textType]);

Adds a text column, with optional textType for MySql text datatype preference where textType defaults to text .

PSQL text type description: variable unlimited length.
