For example is it safe to put this in my .js file that's client side.
Parse.initialize("myAppId");
Parse.serverURL = 'https://0fc98698cc.ngrok.io/1'

Yes, as the docs say, it is safe to use the YOUR_APP_ID, YOUR_JAVASCRIPT_KEY and YOUR_PARSE_SERVER URL on the client side, but NOT the YOUR_MASTERKEY.
Parse.initialize("YOUR_APP_ID", "YOUR_JAVASCRIPT_KEY", "YOUR_MASTERKEY"); //javascriptKey is required only if you have it on server. Parse.serverURL = 'http://YOUR_PARSE_SERVER:1337/parse'
It is totally safe to expose your APP_ID and SERVER_URL. App ID only identify your parse applications if you are hosting more than one parse app on your node process. For instance, if you are mounting more than 1 parse server to an express application, you use different app ids and mounting points.
