We're attempting to create a PHP Laravel application using ReactJS as the view for each page. Laravel handles the routing and the presenting of each view. Each view loads a react js bundle.js file. Each bundle.js file is custom to that view and inside contains the react components needed for that view (screen). What were finding out is that each bundle.js file is about 4MB because each contain its dependencies as well as the components. Also were still trying to figure out how to share a component such as a TableComponent.js file across multiple views but have been so far unsuccessful.
Are we architecting this totally wrong? Should there always be only one bundle.js file for the application as a whole?
Or are there good fixes to remove the dependencies from each bundle.js file in a single dependency js file that gets loaded for all views?
Is there a good way to reuse ReactJS components accross multiple bundle.js files ?
Sounds like a perfect case to use Webpack which is an amazing bundling tool, here is an example on how to build multiple entries(pages):
https://webpack.github.io/docs/multiple-entry-points.html
You just write your entry point code, and webpack will figure out the details on how to build shared dependencies of different entries(pages) into a common bundle.

I'm really a newbie in front-end development. I'm currently involved in a project that does front-end development. I hope I can explain this clearly.
Whenever I call http://localhost:8080/test, it is loaded by page1.jsp.
Now I would like to load a TSX file instead of a JSP. I tried changing my <welcome-file> from page1.jsp to html/js/page2.tsx in web.xml but I don't know why it is not working.
What happened is that a download file window will pop up instead of loading http://localhost:8080/test.
I placed the TSX file in the html/js directory because that's where the package for Typescript and React is located. By the way, the TSX file I'm talking about is a React component that uses Typescript.
Is it possible to configure the web.xml to render the TSX file? If not, is there any other way for me to load it?
Is web.xml still important if I want to load a TSX file?
No, for several reasons:
A .jsp is a "Java server page". You are probably running an application server like Tomcat (I haven't done that in fifteen years or so, so bear with me). It is compiled into a Servlet, which then runs to produce your page as output. Your .tsx file doesn't fit in that process.
Your application server probably has a directory somewhere where you can put static files that don't need to be run on the server side; see if you have a "WebContent" directory or so. In it you can place pure HTML files, Javascript files, fixed images and so on.
But if you put your TSX file there, your browser still won't be able to use it: browsers don't understand Typescript. Typescript needs to be compiled into Javascript, and if you put the resulting .js file there, then a HTML file could use it (with a tag), and that would work.
But your file isn't only Typescript, it's a tsx -- it probably also contains JSX, which also needs to be translated to Javascript.
There are also dependencies, like React, that you'll also need to download in your HTML.
On the whole this is what a bundler like Webpack is for (if you used create-react-app, for instance, you'll get a working Webpack configuration from the start). It can create a "bundle.js" containing all the Javascript needed in one file, including all the dependencies and all your TSX code compiled to Javascript.
Place that in a WebContent or similar directory, call that from a tag in some HTML file -- and you'll hopefully get a nice error message in the console that'll lead you to the first thing I forgot to mention :-)
I know that React and Vue build files are a bunch of HTML, CSS, and JS.
So, what if I want some path (for example /react) is built with React
and another path (for example /vue) is built with Vue
Is it possible to do that?
I'm thinking of building with react/vue and put it on a directory (/react or /vue)
I'm looking to embed my react application into an existing plain html / javascript website. What I've found so far is that you are only able to embed individual components into existing websites, not entire react applications.
Naturally I have an app component which contains the entire application. Am I able to embed the full application by embedding this component? My concern is all the modules I'm using (e.g. axios, bootstrap) will break.
I've been looking for a good tutorial on how to do this but I'm not finding many examples of trying to embed the entire application into an existing page.
My understanding of how to do this, is to reference the react javascript source links in the html page head, possibly also babel although its unclear to me if babel will work. Then we can use the renderDom method like we normally would.
On page load can I run my index.js file to insert my react app component into the dom? If this would work, are there any issues with file structure, file updates I would need to take care of?
If I'm driving off path out into the wilderness and there is a better way to handle it I'm open to suggestions. I'm just looking to see if someone else has experience doing this before I start down a bad path.
I was able to embed my full react application by doing the following...
I built my react app production files with npm run build
I copied those files into the existing web project at the root level
Then I opened the index.html file generated from npm run build and copied the scripts in the head and body sections to the page I wanted to drop in my application
Finally I added a div with the id root (this is what my renderDOM method is looking for) where I wanted my application to appear on the existing web page.
That was it. Super easy, thanks for the help!
Just wanted to add a quick additional approach here.
If you already have a Flask app and you're trying to put React components or an app (so the base component of an app) onto an existing HTML page in the Flask app, basically the only thing that you need is Babel, unless you are able to write React components without using JSX (so in plain Javascript) in which case you'd need nothing.
Step 1: To attach Babel to your project, you'll have to grab the Babel node modules which means your project will be associated with NPM for the sole purpose of using the Babel functions. You can do this by running the following commands in your project root directory (Node.js must be installed):
npm init -y
npm install babel-cli#6 babel-preset-react-app#3
Step 2: Once Babel is attached to your project, you'll have to actually transpile the existing React component .js files from JSX into plain Javascript like so:
npx babel --watch (jsdirectory) --out-dir (outputdirectory) --presets react-app/prod
where (jsdirectory) is the path to the directory where your React component files written using JSX are, and (outputdirectory) is where you want your translated files to show up--use . for (outputdirectory) to have transpiled files appear in your root directory.
Step 3: After the plain Javascript versions of your React files appear, make sure they are linked to your HTML page instead of the original JSX-utilizing files (replace the original script tag's .js file)
Step 4: Make sure the HTML page in question is linked to the .CSS files you want (they will modify the transpiled Javascript in the same manner as they did the JSX files in a project made using Create-React-App because the class names are the same) as well as the required React resources:
<script src="https://unpkg.com/react#16/umd/react.production.min.js" crossorigin></script>
<script src="https://unpkg.com/react-dom#16/umd/react-dom.production.min.js" crossorigin></script>
After you do those quick steps your React components should render no problem on that page in your Python-Flask application.
I am using sencha cmd 6 for building my application.
my folder structure is
classic
src
model
view
account
jobs
portal
portal.js
controller
store
production build process execution is successful but when i load that build its giving .js file not found error.
So i include all js files in folder structure into main js portal.js then .js error is removed and build works.
But i dont want to include all these list of files in one single js, so can we skip the js include part from portal.js and use any property or attribute to include all js files ?
You can specify with * like 'Ext.chart.*' in requires section of Ext.app.Application.
Hope this helps.
Up until now I have been building my application using the following structure.
/src
/components
/shared
/messagebox
/alertbox
/Home
/About
So as you can see I have shared components which are components being used on other components / pages. and I have the concept of Home, About which are also components (which translate to viewable pages) as everything in Angular is now supposed to be a component - right?
Does anyone have a better implementation of the structure of a NG 1.5 app?
I now need to create some filters and as far as I am aware I cannot hang these off of a component, so where is the based place for putting this type of file?
Also other things that come to mind are constants, services etc.
There is no recommendation on Angular docs site as far as I can see.
The one which i used to follow for my project is :
project
/www
/assets
/components // directives
/accordion
/accordion.html
/accordion-directive.js
/accordion-controller.js
/accordion-controller-test.js
/core // shared services
/route
/router-service.js
/sections // pages we build by adding components
/registration-page
/registration.html
/registration-controller.js
/registration-controller-test.js
app.js
index.html
index-controller.js
app-configuration.json // for keeping constants
this might help you.Please check.
