Source maps can be uploaded to Asayer using an NPM module:
npm i @asayerio/sourcemaps-uploader
Upload Source Maps to Asayer
You need to set up your build system to create the various source files. Source maps files must be uploaded to Asayer, otherwise it won't be able to un-minify your stack traces.
Source maps can be uploaded for a single file:
sourcemaps-uploader -k API_KEY -i PROJECT_ID file -m ./dist/app.js.map -u https://mywebsite.com/app.min.js
Or a directory including many files:
sourcemaps-uploader -k API_KEY -i PROJECT_ID dir -m ./dist -u https://mywebsite.com/
