pg-safe-numbers

Summary 

Safe number parsers for pg/sequelize. When unsafe parsing is detected, decision to handle this case is delegated to the
caller. Default action is to throw TypeError exception. You can use your handlers to return parsed value, original
string value, null etc.

Example

Setup your configuration:

// setup-pg-safe-numbers.js

import util from 'util';
import { pgSetTypeParsers } from 'pg-safe-numbers';

// Setup parsers for unsafe numbers.
pgSetTypeParsers({

// Handle unsafe integers, ie. >= Math.pow(2, 53)
unsafeInt(parsed, text) {
console.error(Unsafe int ${util.inspect(text)}) parse to ${util.inspect(parsed)}.\n${new Error().stack});
return parsed;
},

// Handle unsafe floats.
unsafeFloat(parsed, text) {
console.error(Unsafe float ${util.inspect(text)}) parse to ${util.inspect(parsed)}.\n${new Error().stack});
return parsed;
}

});

// Or simply to use default TypeError throw:
// pgSetTypeParsers();

And:

// my.js

require('./setup-pg-safe-numbers'); // NOTE: Doesn't really need to be before importing sequelize.
import Sequelize from 'sequelize';
