When managing dates, it is good practice to choose only one robust library and stick to it. To look up later, I wanted to keep one specific moment.js usage here.

Solution

Start date of the previous month

const startDate = moment().add(-1, 'months').startOf('month');

End date of the previous month

const endDate = moment().add(-1, 'months').endOf('month');

Conclusion

Thank you for reading! I hope you have found this post helpful.
