I'm building a project in Vue.js, but it has a quite a lot of Javascript processing (it's all local, so I don't need to have anything server side), and I was wondering if there is a way to import a file that is basically just some processing (mathematical, structure processing, etc.) functions in Javascript - no template, etc. - into a Vue component? It's all working fine using methods in the component, but getting a bit large and "monolithic".
You can keep working with several files and then just to the following.
import AlgebraicFunctions from 'algebraic-file';
import GeometricFunctions from 'geometric-file';
Using the spread operator:
methods: {
...AlgebraicFunctions,
...GeometricFunctions
}

I am learning React.js, and I have noticed that each React file appears to be just a mix of JavaScript and HTML. But I enjoy having distinct files for my HTML and JS. So, I am wondering if I can have these two independent files but also include a link (or something) in either the HTML or JS file, so that they may communicate with one another.
Thank you.
React components implement a render() method that takes input data and returns what to display. This example uses an XML-like syntax called JSX. Input data that is passed into the component can be accessed by render() via this.props.
In other words, it was more simple than we separate html and render it on React, as a component.
If we still want to access html page via any page that created with react, we can did it via a href.
For any other way like import it (maybe), i think it was too complicated because of some reason.
Hope you will more understand about react with this react docs link
React is used to build single-page applications which is an application that loads a single HTML page and all the necessary assets (such as JavaScript and CSS) required for the application to run . this single HTML page is index.html located in the public folder (if you're using create-react-app)
I was trying flutter but do not like it so have started looking for react libays to use instead and a came across matierial ui which is great as it has the flutter components (why I considered flutter in the first place) but is built in react. I would like to use this in my projects however am struggling to import it. I have tried a number of different urls for the file including:
https://cdn.jsdelivr.net/npm/#material-ui/core
#material-ui/core
https://cdn.skypack.dev/#material-ui/core
and a number of ways of importing it incliding
import * as ui from "[url]" (js)
script(src="[url]" type="module" crossorigin) (pug)
I have a Meteor app built using blaze. Now I am shifting the UI to react. I have just started learning react and hence I am confused how to use #with, #each, etc., in reactjs.
Code Sample:
<div className="page-content {{#unless}} FLT rd-body {{/unless}}">
How to use '#unless', '#with' and other Meteor components in ReactJS?
Also, how to use Session variables in reactjs?
React is a library to create web-ui e.g. the 'view-layer'. Meteor is a framework, build-system and server all-in-one.
Blaze is the default view-layer. In Blaze you can make your html dynamic with the {{ .. }} tags, as you use above.
React works differently. React templates are Javascript files mixed with HTML. Usually with extension .jsx. I'd visit https://reactjs.org/ for more information, or one of the many tutorials and books that exist.
Read the manuals:
https://guide.meteor.com/react.html
and
https://www.meteor.com/tutorials/react/creating-an-app.
Especially the first link.
It contains the syntax to embed react JSX into blaze templates or use blaze templates as JSX components. So you basically have to decide which templating system you're going to cast to the other system.
Concerning the session variables, have a look at the react documentation.
I'm working on a webpage and I want to visualize a certain tree structure.
I bumped into this beautiful D3.js tree (http://bl.ocks.org/robschmuecker/7880033), but I'm having trouble importing it into my project since there are several ways (dg3-ng2 for example).
D3.js is a javascript-libary - and Angular works with typescript.
How do I integrate that certain tree into my project so that I also can modify it without any trouble afterwards?
I do have several questions like:
Where do I import the .js and the .json file?
Do I have to convert the javascript code into typescript manually?
Should I write the .js code into a .ts file?
Should I make a reference in my index.html?
Should I make use of a D3-Service?
As you can see I'm quiet confused.
If you use Angular, it's simple)
Istall d3 from npm.
Import d3 in component like that:
import * as d3 from 'd3';
And write you logic, use d3 syntaxis, example:
constructor(private element: ElementRef) {
this.htmlElement = this.element.nativeElement;
this.host = d3.select(this.element.nativeElement);
}
You graphic is a component, in you component descrite functions to build svg, draw axis and etc.
Then on init of component call methods that you describe, example:
ngOnInit(): void {
this.setup();
this.buildSVG();
this.drawFirstPlanRects();
this.drawSecondPlanRects();
this.drawXAxis();
this.drawYAxis();
this.drawCrossLines();
}
I'd strongly recommend using angular-cli since when you install the d3 library you won't have to deal with the boiler plate of hooking it into the app properly. You'd just need to import it into your ts document like the above example shows. On importing the json there are several different ways that it could be handled. You could just store the json in a variable in the .ts file, you could store it in a static json document that you then host along with the app and there a many examples of pulling files and loading json data out there already.
You don't have to convert any of the js code you have since ts is essentially js with types, though you might have to declare an any type for some things, but if you want ts code you will have to manually convert or find a ts example. I'd strongly recommend a good IDE that is compatible with ts. It'll do a lot of the heavy lifting of finding mistakes.
It's rather difficult to answer that question since I don't know the specs of your project. Generally if you are doing a one off thing that does't need angular I'd just keep it simple with js and drop the usage of angular. If this is part of a larger app though I'd recommend writing it in ts since angular2+ is written in ts and most examples you find online will be in ts.
If you are using angular-cli you won't need to make a reference in your index.html file
I'm not sure what you are asking here.
From the questions you are asking I'd strongly recommend really looking at angular and learning how to properly create an app with it and then figure out how to integrate d3 int the project, since some of the questions you are asking aren't related to just working with d3 in angular.
how to import different methods from different files to another javascript file for page objects E2E testing using protractor.
like i am dividing the page-objects as per each individual page and writing the all possible actions on that page as methods.
so, how to import those methods from multiple pages(files) to my test file.
You just use require to import your page objects into the specs:
var myPage = require("./po/mypage.po.js");
See examples at:
