Ethers/Big Numbers

1.0.0Last update Aug 16, 2024

This codemod migrates BigNumber in v5 to BigInt in v6 in ethers.js library. It also changes the syntax for addition, and checking equality according to v6.

Example

Before

// Using BigNumber in v5
value = BigNumber.from('1000');
// Adding two values in v5
sum = value1.add(value2);
// Checking equality in v5
isEqual = value1.eq(value2);

After

// Using BigInt in v6
value = BigInt('1000');
// Addition, keep in mind, both values must be a BigInt
sum = value1 + value2;
// Checking equality
isEqual = value1 == value2;
