# Postgres Error Codes
Postgres error codes mapping for NodeJS.
## Install
```
npm i @drdgvhbh/postgres-error-codes
```
## Usage
Each condition from the [PG documentation](https://www.postgresql.org/docs/9.2/errcodes-appendix.html) is available in the module. In order to obtain the status code use the prefixed uppercase condition name:
`unique_violation` => `PG_UNIQUE_VIOLATION`
`not_null_violation` => `PG_NOT_NULL_VIOLATION`
```javascript
const { PG_UNIQUE_VIOLATION, PG_NOT_NULL_VIOLATION } = require('postgres-error-codes')
async function createUserMethod(req, res, next) {
try {
// Run insert user SQL
} catch (err) {
// If user with same email already exists
if (err.code === PG_UNIQUE_VIOLATION) {
return next('Email already exists!')
}
// Param should not be null
if (err.code === PG_NOT_NULL_VIOLATION) {
return next('Email required!')
}
next(err)
}
}
```
