Does the Web App Manifest include order matter?



I am trying to add PWA functionality to a simple site, and I am running into odd issues with Chrome version 68.0.3440.106.



I am running on http://localhost:4502 for my testing, in the context of a CMS (so I am working within a few constraints). Also, note that I removed all my PWA/Service Worker code so there is no caching at play.



In the <head> .. I include the manifest via:


<head>


<link rel="manifest" href="/content/foo/bar.pwa.manifest.webmanifest" type="application/manifest+json">



(The "odd" name of the manifest file is a constraint of the CMS i'm working in; i've also used the "json" extension to the same effect as described below).



Which contains...


"name":"Sample",
"short_name":"sample",
"theme_color":"#001F3F",
"background_color":"#FF4136",
"display":"standalone",
"scope":".",
"start_url":"/content/foo/bar.html",
"icons":["src":"/content/assets/sample.jpg","size":"192x192","type":"image/jpeg","src":"/content/assets/sample.jpg","size":"512x512","type":"image/jpeg","src":"/content/assets/sample.jpg","size":"144x144","type":"image/jpeg"]



I've observed the following:
When I have JS/CSS includes ABOVE my <link rel="manifest" .. things go haywire.
* If i copy the page's URL, paste it into a NEW chrome tab (a refresh of an existing tab does not cut it), and open up Chrome Dev Tools FOR that new tab, I can see the HTTP request/response for the manifest, and in Dev Tools > Application > Manifest is appears to display everything correctly. (so far so good).
* If I then REFRESH this tab, i don't see the request for the manifest and the Application > Manifest section is blank. The HTML source has not changed at all.
* No matter how many times I refresh it doesn't seem to help (also clear cache, etc.)


<link rel="manifest" ..



2) When i move the <link rel="manifest" to be ABOVE any CSS/JS in the <head> it seems to load consistently and correctly. Refreshing the page the HTTP request for the manifest displays, and Application > Manifest displays the correct info.


<link rel="manifest"


<head>



I've been scouring docs (Google, MDN) to see if the manifest MUST be included before ANY other includes, but I can't find anything that says that - and it's odd that on the first load of a tab, it seems to work even when included after CSS/JS.



Im hoping there is a way to get this to load regardless of where in the <head> the <link rel="manifest".. happens to be (as the CMS makes it hard to guarantee the order)


<head>


<link rel="manifest"..

No, the relative position of the <link rel="manifest"> within your page's <head> does not make a difference from the perspective of how it's parsed and interpreted.


<link rel="manifest">


<head>



I'm hard pressed to explain the behavior you're seeing, other than perhaps a syntax error in the HTML that includes your JavaScript and CSS, causing the subsequent <link rel="manifest"> to be parsed incorrectly. But in general, the position shouldn't matter.


<link rel="manifest">

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas...

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12...

Creating a leaderboard in HTML/JS

Image
Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]...
