Google	Official Google Blog	Hear educators' stories this Teacher Appreciation Week	http://feedproxy.google.com/~r/blogspot/MKuf/~3/u4R9lDWop3Q/	Hear educators x stories this Teacher Appreciation WeekEditor s note In honor of Teacher Appreciation Week   National Teacher of the Year Tabatha Rosproy is sharing her story as well as some of the ways Google is supporting teachers this year   Every year Teacher Appreciation Week falls near the end of the school year which is an emotional time for many teachers Saying goodbye to our students is always tough and after a year of educating during a pandemic those emotions are more prominent than ever As National Teacher of the Year I ve had the honor of hearing hundreds of teachers stories over the past months I can say with confidence that this year educators have truly given everything they have There are the things people see like teaching lessons holding meetings and keeping kids on track academically But there is also work most people don t see like the hour days or the extra mile we go to comfort children who are not our own Those invisible moments are a critical piece of every teacher s story  So this week I hope that you ll join us in listening to teachers stories to uncover some of these invisible moments ーand celebrating the teachers who have shaped your own story Sharing teachers stories with StoryCorpsIn addition to today s Doodle which includes five teacher stories from the StoryCorps archives Google and the Council of Chief State School Officers CCSSO are teaming up to support StoryCorps new Thank an Educator campaign Anyone can use StoryCorps self directed recording tools to record their stories so you can grab a friend or family member and start reflecting upon the ways in which your favorite teacher changed your life In the midst of one of the most challenging school years to date the campaign hopes to spark a moment of gratitude for teachers everywhere Be sure to check out their website to hear my recording and those from other State Teachers of the Year Expanding access to inclusive stories with The Conscious KidBooks and reading materials are crucial practical tools that enable teachers to bring more of the world to their kids and help them develop kindness and empathy for the people around them Google and The Conscious Kid are building upon their work together to provide educators with recommended titles and evaluation criteria for bringing new materials into their classrooms  In honor of Teacher Appreciation Week their free inclusive reading guide ーwith book recommendations spanning Pre K through th grade ーhas been updated to include more than new titles And as part of their broader efforts to honor Asian Pacific American Heritage Month APAHM Google and The Conscious Kid are sending a free set of curated books by Asian authors featuring AAPI protagonists to classrooms across the country starting with eligible teachers at Title I schools Teachers can request these titles for their classrooms and anyone can contribute to the fund here  In addition The Conscious Kid has collaborated with Wong Fu Productions to bring four of the books to life in a series of read alongs on Asian American heritage and culture Rolling out with Harry Shum Jr reading Grandpa Grumps by Katrina Moore the videos will be released weekly onThe Conscious Kid s YouTube channel and in theYouTube Kids app s learning category throughout the month of May Supporting more inclusive classrooms with DonorsChoose Since Google org has committed more than million directly to teacher focused organizations and initiatives Starting Wednesday Google org will match donations up to ーdollar for dollar ーfor projects created by teachers of color as well as projects from all teachers requesting culturally responsive and antiracist resources such as books posters and more for their classrooms as part of their continued support of the DonorsChoose ISeeMe campaign And every dollar donated to projects created by male educators of color ーa group historically underrepresented in the field ーwill receive a two dollar match from Google org Learn more about ISeeMe setting up a campaign or supporting a classroom on the DonorsChoose website Introducing the new National Teacher of the YearThe new National Teacher of the Year will be announced soon and I ll be joining them for a conversation through Google s Education OnAir series on Friday May  Be sure to tune in to hear their incredible stories ーI can t wait for you to meet them As an early childhood educator it s especially important to me that every one of my students knows from a young age that they belong and sees themselves reflected in the stories we tell in our classrooms Thank you to every educator putting in the work to ensure every student feels included and valued Finally as you re thinking about ways you can appreciate the educators in your life beyond Teacher Appreciation Week remember that one of the best ways to support teachers is to listen to their stories elevate their voices and advocate for their jobs and their livelihood Together we can continue to do the work of supporting our children who will author our future	2021-05-03 14:00:00

and SASS Shorthands for code efficiencyCSS may look exhausting and not very many individuals can dominate it the correct way So in this post we ve written about CSS tricks and tips you should know also SASS mixins shorthand you should know Notwithstanding it is an expertise that can give you an incredible upper hand over different designers On the off chance that you like addressing puzzles you will discover bliss recorded as a hard copy CSS by viewing at it as a riddle to settle Let s look into some amazing CSS tricks Smooth ScrollingWhen you visit some websites and try to got to different sections it scrolls smoothly to that section You can achieve this feature on your website by using one line CSS html scroll behavior smooth Prevent lt textarea gt resizeYou can use the resize property to prevent lt textarea gt element form being resized or limit it to one axis textarea no resize resize none textarea horizontal resize resize horizontal textarea vertical resize resize vertical Drop

occasionally with amazing news resources and many thing Useful CSS Pseudo elements selectorsPseudo elements are a way to select and style a specific part of an element You can think of them as a sub element that are created as part of standard HTML elements How is it different pseudo class A pseudo class is used to select an element in a specific state like hover or focus A pseudo element is used to select a specific part of an element like first letter Pseudo element selectors begin with two colons as a way to differentiate them from pseudo classes This was only introduced in CSS therefore some selectors are backwards compatible and work with a single color before and afterCreates a pseudo element that is the child of the selected element The before pseudo element is assigned as the first child and after is the last main text font style italic main text before main text after content color wheat SUPPORTED IN ALL MODERN BROWSERS first lineApplies styles of the first line of a block level element Keep in mind that the length of the first line will depend on the width of the element or viewport p first line color wheat text decoration underline placeholderRepresents the

mixinsUsing SASS makes your CSS codes very efficient SASS is a CSS preprocessor and we have used it in almost every project Here I am sharing some SASS mixins you can use to make your code efficient Center BlocksWe always find our self needing to center a block element so this mixin saves me a little typing css mixin center block margin left auto right auto Use case wrapper include center block Output wrapper margin left auto margin right auto PseudoWhen using pseudo element you always need these properties so why not put them in a mixin css mixin pseudo display block pos absolute content conent content display display position pos css Use case default element before include pseudo output element before content display block position absolute css Use case with args element befire include pseudo inline block relative output element before content display inline block position relative RatioA ratio mixin to create scalable elements usually images Since aspect ratio isn t very well supported yet this alternative is useful css mixin responsive ratio x y padding top unquote y x use case wide image include responsive ratio output wide image padding top TruncateTruncating text is another useful mixin have since it can be easy to forget the syntax css mixin truncate width limit max width width limit white space nowrap overflow hidden text overflow hidden text overflow ellipsis Use case excerpt include truncate rem output excerpt max width rem white space nowrap overflow hidden text overflow ellipsis Cover backgroundIf you re working a lot with cover background images this one can save a lot of typing css mixin cover background image src background image url image src background repeat no repeat background size cover background position center use case hero include cover background image main png output hero background image url image main png background repeat no repeat background size cover background position center OrganizingKeep you SCSS files organized by keeping you mixing in a separate file Since mixins don t generate any output until they are used it s easier to keep them in a separate file and import whenever you need to use one css keep all mixins together import mixin scss Separate files for mixins import center block scss import pseudo scss import responsive ratio scss import truncate scss import cover background scss Thank

海外TECH	DEV Community	Build a Reddit Clone with React and Dgraph Cloud	https://dev.to/thawkin3/build-a-reddit-clone-with-react-and-dgraph-cloud-4do1	Build a Reddit Clone with React and Dgraph CloudSocial media apps are perfect candidates for using graph databases and GraphQL APIs The combinations of complex data queries and relationships are endless Take Reddit for example The app consists of “subreddits or topics Users can create posts in these subreddits which means that there is a many to one relationship between posts and subreddits Each post belongs to exactly one subreddit and each subreddit can contain many posts Users can comment on posts leading to another many to one relationship between posts and comments Each comment belongs to exactly one post and each post can have many comments There is also a many to one relationship between users and posts and between users and comments Each comment and post is made by a single user and a single user can have many comments and posts In an app like Reddit each page of the app requires different subsets of this data Using traditional REST API endpoints could mean developing several unique endpoints each tailored to meet the needs of a specific use case GraphQL APIs however are based around the idea of having a single API endpoint that developers can use to pick and choose the relevant pieces of data they need for any given page This article will highlight the flexibility of GraphQL and how easy using a hosted backend from Dgraph Cloud makes it for frontend developers to get exactly the data they need for each page of their app Demo App ーReaditThe demo app we ll be using throughout the rest of the article is Readit a Reddit clone but for book lovers …get it The app is built using React for the UIReact Router for the client side routingDgraph Cloud for the GraphQL backend and databaseApollo Client for facilitating the communication between the frontend and the backendAs noted above the basic data types in the app are subreddits “subreadits ha… posts comments and users A diagram may be helpful to visually highlight the relationships between each of these nodes that make up our graph Node relationships in the graphThe app contains routes for viewing the home page viewing a single subreadit viewing a specific post and viewing an individual user Here we see the home page Readit home pageIf you d like to follow along at home or try this out on your machine all of the code for this app can be found on GitHub You can also view the demo app here Configuring the Dgraph Cloud BackendNow that we have an overview of the app let s get started First we ll create a backend with Dgraph Cloud For those not familiar with this service Dgraph is a native GraphQL graph database built for the cloud With a little configuration you get a graph database as well as an API endpoint for working with your database Dgraph s free tier is great for learning and getting started so that s what I used More advanced features like shared and dedicated clusters are available on additional paid tiers if you need to make your backend production ready After signing in to our account we click the “Launch a new backend button which will bring up the following setup page Configuring a new Dgraph Cloud backendSince this is a demo app we can choose the Starter option for the product type Production apps should use a higher tier with a shared or dedicated instance though I left my region as “us west since that s the region closest to me I used “reddit clone for the name but feel free to use whatever you like After filling out all the options we can click “Launch to spin up the new backend Once the backend has been created we ll see an overview page with the new backend API endpoint New backend API endpointNow it s time to build a schema This schema declares the various types of data that we ll be working with in our app and storing in our database We can either enter our schema info directly in the Schema Editor or for a more interactive experience use UI Mode Let s use UI Mode to create our schema The GUI helps us configure our types their fields and even the relationship between various types and fields Creating a schema in UI ModeAfter creating the schema we can click the “Deploy button to make it official If we now look at the Schema Editor view we ll see the resulting GraphQL snippet type Comment id ID commentContent String user User hasInverse field comments post Post hasInverse field comments voteCount Int type Post id ID title String subreadit Subreadit hasInverse field posts user User hasInverse field posts voteCount Int comments Comment hasInverse field post type Subreadit id ID name String search by exact description String posts Post hasInverse field subreadit type User id ID userName String search by exact bio String comments Comment hasInverse field user posts Post hasInverse field user As you can see each field has an associated type For instance the Comment type we created has an id field that contains a unique identifier generated by Dgraph Cloud It has a commentContent field which contains the string text entered by the user It has a voteCount field which is an integer representing the number of votes the comment has received Finally the user field references the user that wrote the comment and the post field references the post on which the comment was made The relationship between the comment and the user is designated by the hasInverse directive which tells Dgraph Cloud that the Comment type is linked to the User type by the comments field on the User type The same is true for the relationship between the comment and the post You ll also notice that a few of our fields include the search directive This allows us to filter our queries by these searchable fields For instance we can find a specific subreddit by filtering our query results by a specific string of text for the name field The same is true when filtering user results by their userName field The next step is to populate the database with some seed data which we can do using the API Explorer We won t go through all the mutations necessary to populate the data in this article but you can view the GraphQL snippets here These snippets are used to create the subreadits users posts and comments For example here s what I used to create a few subreadits mutation AddSubreadits addSubreadit input name description A dystopian social science fiction novel by English novelist George Orwell name fahrenheit description A future American society where books are outlawed and firemen burn any that are found name thecatcherintherye description Holden Caulfield an angry depressed year old lives in an unspecified institution in California after the end of World War II subreadit id name description Configuring the FrontendNow that we have the backend created we can move along to building the frontend We ll use create react app to generate a skeleton app as a starting point and then continue to build upon the app from there yarn create react app reddit clonecd reddit cloneNext we ll install react router dom so that we can do client side routing in the single page app with React Router yarn add react router domUsing React Router we can create routes for each of our pages home subreadit post and user Below is the App component with each of its routes import React from react import BrowserRouter as Router Switch Route Redirect from react router dom import Nav from components Nav import HomePage from pages HomePage import PostPageWithRouter from pages PostPage import SubreaditPageWithRouter from pages SubreaditPage import UserPageWithRouter from pages UserPage import App css export function App return lt Router basename reddit clone build gt

gt lt UserPageWithRouter gt lt Route gt lt Route path gt lt HomePage gt lt Route gt lt Route path gt lt Redirect to gt lt Route gt lt Switch gt lt main gt lt div gt lt Router gt Then we ll install a couple of packages for Apollo Client which is a JavaScript state management library for working with GraphQL While it s possible to make requests to a GraphQL API endpoint directly using something like the fetch API Apollo Client makes this process even simpler yarn add apollo client graphql You ll note that we ve installed the graphql package as well as the apollo client package even though we never directly use the graphql package in our code This is because graphql is a peerDependency of apollo client and is used internally to facilitate working with GraphQL in JavaScript Now that we have Apollo Client installed we can easily query data from the GraphQL backend and consume it in our React components We can first create the Apollo client like so import ApolloClient InMemoryCache from apollo client export const apolloClient new ApolloClient uri cache new InMemoryCache And then we can wrap our main App component in the ApolloProvider in the index js file import React from react import ReactDOM from react dom import ApolloProvider from apollo client import index css import App from App import apolloClient from apolloClient ReactDOM render lt React StrictMode gt lt ApolloProvider client apolloClient gt lt App gt lt ApolloProvider gt lt React StrictMode gt document getElementById root Home PageNow that we have our routing set up and Apollo ready to go we can begin building the pages for each of our routes The home page shows a list of popular subreadits and a list of popular users Readit home pageWe can query our endpoint for that information and then use Apollo to declaratively handle the loading error and response data states The code for the HomePage component is reproduced in full below import React from react import useQuery gql from apollo client import Subreadit from components Subreadit import User from components User import LoadingSpinner from components LoadingSpinner import ErrorMessage from components ErrorMessage import HomePage css const FETCH SUBREADITS AND USERS gql query FetchSubreaditsAndUsers querySubreadit name description queryUser userName bio postsAggregate count commentsAggregate count export const HomePage gt const

s posts and comments The only thing we re interested in for the home page is how many posts and how many comments each user has We can use the count field from postsAggregate and commentsAggregate to find the relevant numbers Subreadit PageIf we click on one of the subreadits from the home page we ll be taken to that particular subreadit s page where we can see all the posts under that topic Readit subreadit page for the subreaditOn this page we need the data for the subreadit name and description just like we did on the home page We now also need to fetch all of the posts that are part of this subreadit For each post we need the post title the number of votes and comments and the username of the user who posted it We don t need the actual comments yet though since they re not displayed on this page Here s the code for the SubreaditPage component import React from react import useQuery gql from apollo client import withRouter from react router dom import Subreadit from

original post as well as all of the comments on the post Readit post page for Oscar s postHere we need all the same post data that we did on the subreadit page but now we also need to know the subreadit it was posted on and we need all of the comments on the post For each comment we need to know the username for the user who posted it what the actual comment content was and how many votes it has The code for the PostPage looks like this import React from react import useQuery gql from apollo client import withRouter from react router dom import Post from components Post import Comment

PageFinally if we decide to view a user s profile we can see all of their posts and comments they ve made Readit user page for Oscar MartinezThis page should show the user s username bio number of posts and number of comments We also need all of their posts and all of their comments On each post we need to know the subreadit it was posted on the post title as well as the number of votes and comments For each comment we need to know which post it was a comment on what the comment content was and the number of votes it s received The code for the UserPage is below import React from react

withRouter UserPage This page is by far the most complex as we need to query more than just summary data or aggregate count data ConclusionAs we ve seen each page in our app requires unique portions of data Some pages need only high level summaries like the number of comments or posts a user has made Other pages need more in depth results like the actual comments and actual posts Depending on the page you may need more or less information The benefit of using GraphQL and Dgraph Cloud is the flexibility in querying exactly the data we need for each page ーno more and no less For each request we used the same single API endpoint but requested different fields This greatly simplifies the development work as we don t need to create a new backend endpoint for each page Or worse create a single endpoint that retrieves a monstrous payload of data we then have to sift through to find the minor subset of data that we need GraphQL makes it easy to quickly and painlessly request exactly the right data exactly when you need it	2021-05-03 12:21:22
