package.json install script references yarn, but none of the dependencies install it, should it be added there? Running npm i minidump as instructed in the README generates the following error:

npm error command sh -c yarn submodule && node build.js
npm error sh: 1: yarn: not found

Running npm i yarn before trying to install minidump seems to help ([email protected] for [email protected] worked for me at the time of writing this report).

Happy to make a PR if it's as simple as adding it to package.json (but I admit I know nothing about yarn and if there's some reason you wouldn't want to do that as there often seems to be with overenthusiastic build systems ^_^)
