Gatsby Blog with Contentful CMS, how to sort blog posts by date



My query looks like this(i have left some variables out):


allContentfulBlog(
filter: node_locale: eq: "en-US"
sort: fields: [node___date], order: DESC
)
edges
node
id
date(formatString: "DD MMMM, YYYY")





Terminal error:



GraphQL Error Argument "sort" has invalid value fields:
[node___date], order: DESC. In field "fields": In element #0:
Expected type "ContentfulBlogConnectionSortByFieldsEnum", found
node___date.



For sorting this i tried all arguments i saw in tutorials or could think of. I think its something regarding Contentful and it's data format that goes into my gatsby app.

This did the trick:



sort: fields: [date], order: DESC



I found it in a Gatsby-Contentful-Starter; I had the false impression the syntax needs to be something like fieldName___argumentByWichToSort





For figuring out the right queries I can highly recommend the included GraphiQL interface. :) With this you have a powerful autocompletion at hand. gatsbyjs.org/tutorial/part-five/#introducing-graphiql

@stefanjudis GraphiQL doesn't work with arguments like filter or sort, nor suggests them when you press Ctrl + Enter

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]...
