But when I store a very large data in my postgres it throws error '''integer out of range'''

My question is how can I store Big Int as type in psql using typeorm

Answer 1

Define type bigint in @Column decorator,

@Column({type: 'bigint'})
columnName: string;

Note: that based on TypeOrm documentation bigint is mapped to string.
