• Moving appended path in a div (d3.js)

  I have a map that I seem to be unable to move the position of. Here's my HTML:

  <div class="container">
      <!-- Title -->
      <h1 class="title has-text-centered">New York</h1>
      <h2 class="subtitle has-text-centered">Income vs Poverty</h2>
  
      <div class="columns">
        <div class="column is-half">
          <svg class="current" width="780" height="850" style="text-align:left;" ></svg>
        </div>
         <div class="column is-half">
          <svg class="2015" width="580" height="800"></svg>
        </div>
      </div>
  

  And here's where I draw the map and append it to the 'current' svg:

   var geoPath = d3.geoPath()
  .projection( albersProjection );
  
  
  
  d3.select("svg.current").selectAll("path")
  .data( CaliforniaCountiesOverdoses.features )
  .enter()
  .append( "path" )
  .attr( "fill", "white" )
  .attr( "opacity", .8 )
  .attr( "stroke", "#696969" )
  .attr("left", 200)
  .attr( "border-radius", '50%' )
  .attr( "stroke-width", ".35" )
  .attr( "d", geoPath )
      .attr("class","counties")
  
      .attr("fill", function(d) { 
          var value = currentMap.get(d.properties.ID);
          return (value != 0 ? current_color(value) : "grey");  
  

  The problem is I can't move the map (i.e the 'counties' class within the SVG rectangle. I'd like it to be way further to the left. I've tried to set the viewBox of the 'counties' class :

  $('counties').each(function () { $(this)[0].setAttribute('viewBox', '0 0 100 100') });
  

  And Ive tried other CSS manipulation:

  .counties {
  
   text-align: left;
  

  }

  All with no luck. Can any one tell me what i'm missing in my approach here?

• React - Game of Life - Update state of specific elements in 2D array depending on which elements are clicked by user

  I'm still learning React and working on coding John Conway's Game of Life. I have created a game board for the game using a 2D array in state. I have this 2D array stored in state in my App.js. I also have two functional components, Gameboard.js and Square.js receiving props and creating the game board.

  Gameboard.js creates a table and passed props to Square.js letting it know which squares should be highlighted and which shouldn't. In other words it let's each individual square know if the user has clicked it and if it's "alive" in the Game of Life sense.

  After a user clicks a specific square in Square.js I have a callback function triggered onClick. The callback function, aliveCallback, passes the X and Y coordinates of the specific square that was clicked back to App.js. App.js triggers a function called alive.

  When alive is called I need to update the state of the 2D array so that the specific square (it's X and Y coordinates, for example [0, 0] or [0, 1] etc...) is set to the boolean stored in state. Then, this boolean can be passed to Gameboard.js as isAlive. The game board then passes that isAlive value to Square.js and Square.js has conditional rendering that tells that individual square to be highlighted light blue.

  This has been a mouth full and it would probably be easiest to check out the Codesandbox and see the structure of the project. It also helps to mention that I am following advice a SO poster gave me in this post.

  After doing some reading and looking at the React docs it appears a good approach to this issue is to use immutability-helper and it's update function. That's the approach I have taken but I can't seem to properly update the state of the specific square clicked using it's X and Y coordinates.

  Instead of posting code here it would probably just be easier and neater to check out the code on CodeSandbox. How can I write my alive function so that it properly updates the state of whatever square is clicked on?

  Here is what I've tried:

  alive = (x, y) => {
      console.log(x, y);
  
      const data = this.state.board;
      const ySquare = y;
      const xSquare = x;
      console.log("X square is : " + xSquare);
      console.log("Y square is : " + ySquare);
  
      const updateData = update(data, {
        xSquare: {$set: this.setState({ alive: !this.state.alive })}
      });
  
    }
  

  The logic here is to try to pass xSquare and ySquare to update and then try to set alive to true for that particular square.
• Electron - mainWindow.webContents.executeJavaScript() with a file instead of text

  I'm building an application where I can't use a webview since it can't do everything I would like, whereas using the mainWindow does.

  However, I need to use a whole javascript file rather than just text.

  Example:

  const {app, BrowserWindow} = require('electron');
  
  let mainWindow;
  
  app.on('ready', function() {
      mainWindow = new BrowserWindow({
          width: 1024,
          height: 1024
      });
      mainWindow.loadURL("https://www.google.com/");
      mainWindow.webContents.executeJavaScript('alert("this is a test!");');
  
      // I want to load an entire file for the .executeJavaScript()
      // I have a file within the same directory called 'index.js'
      // How would I implement this?
      mainWindow.webContents.executeJavaScript('???');
  });
  
• assert.throws says => Missing expected exception

  I am using this chunk of code:

         assert.throws(async () => {
              patientSubscriber = await PatientSubscriber.create({
                  isSubscribed: true,
                  patient: patient._id,
                  subscriber: user._id
              });
          },{
               message: /foo/
          });
  

  when I run it I get this:

  AssertionError [ERR_ASSERTION]: Missing expected exception.

  The assert API is: https://nodejs.org/api/assert.html#assert_assert_throws_fn_error_message

  Maybe I am hitting this issue? https://github.com/nodejs/node-v0.x-archive/issues/8368

  Anyone know what that error is about?
• How to abort a FireStore transaction if any write operation fails?

  In the code below, I am updating two documents in a transaction. However, if only one of the update succeeds and the other one fails for whatever reason, FireStore will complete the transaction anyways. How do I abort the transaction if any of the write operations fail?

  var country; // forget to set a value to this variable
  // Create a reference to the SF doc.
  var sfDocRef = db.collection("cities").doc("SF");
  var usaDocRef = db.collection("country").doc(country);  //country is undefined  
  db.runTransaction(function(transaction) {
      return transaction.get(sfDocRef).then(function(sfDoc) {
          if (!sfDoc.exists) {
              throw "Document does not exist!";
          }
  
          var newPopulation = sfDoc.data().population + 1;
          if (newPopulation <= 1000000) {
              transaction.update(sfDocRef, { population: newPopulation }); //Will succeed
              transaction.update(usaDocRef, { lastPopulationUpdate: new Date()}); //Will fail
              return newPopulation;
          } else {
              return Promise.reject("Sorry! Population is too big.");
          }
      });
  }).then(function(newPopulation) {
      console.log("Population increased to ", newPopulation);
  }).catch(function(err) {
      // This will be an "population is too big" error.
      console.error(err);
  });
  

  In the above example, we forgot to assign a value to country .
