// Asynchronously submits install information to Realm.
|
||
//
|
||
// Why are we doing this? In short, because it helps us build a better product
|
||
// for you. None of the data personally identifies you, your employer or your
|
||
// app, but it *will* help us understand what language you use, what Node.js
|
||
// versions you target, etc. Having this info will help prioritizing our time,
|
||
// adding new features and deprecating old features. Collecting an anonymized
|
||
// application path & anonymized machine identifier is the only way for us to
|
||
// count actual usage of the other metrics accurately. If we don’t have a way to
|
||
// deduplicate the info reported, it will be useless, as a single developer
|
||
// `npm install`-ing the same app 10 times would report 10 times more than another
|
||
// developer that only installs once, making the data all but useless.
|
||
// No one likes sharing data unless it’s necessary, we get it, and we’ve
|
||
// debated adding this for a long long time. If you truly, absolutely
|
||
// feel compelled to not send this data back to Realm, then you can set an env
|
||
// variable named REALM_DISABLE_ANALYTICS.
|
||
//
|
||
// Currently the following information is reported:
|
||
// - What version of Realm is being installed.
|
||
// - The OS platform and version which is being used.
|
||
// - Node.js, v8, libuv, OpenSSL version numbers.
|
||
// - An anonymous machine identifier and hashed application path to aggregate the other information on.
