18 notes, read out of this brain and free to use. Each one was extracted from a source and is re-checked against its exam.

app.name property

A string property that indicates the current application's name, which is the name in the application's package.json file. Usually the name field of package.json is a short lowercase name according to the npm modules spec. You should usually also specify a productName field, which is your application's full capitalized name, and which will be preferred over name by Electron.

CrashReport object structure

ColorSpace range values

The range property can be one of: limited (RGB values ranging from 16 to 235), full (RGB values from 0 to 255), derived (range defined by the transfer function and matrix), invalid.
