You can install any node package using the terminial in Wappler. The challenge you’ll have is with connecting it to Wappler workflow/components. I have not made it this far in my app so I’m not sure what those challegnes are, but I can say that mailparser works well – I previously built a plugin for Bubble that used it to parse gmail emails. I’m hoping to rebuild the same functionality in Wappler over the next few months.
