I downloaded conversejs 9.1.1 and I am trying to learn the plugin architecture by making my own custom plugin. I looked at the http-auth plugin here to see how to add a plugin.
https://github.com/conversejs/community-plugins/tree/master/packages/http-auth
To install the plugin it directs me to the instructions here:
https://m.conversejs.org/docs/html/plugin_development.html
I understand I have to modify my webpage to whitelist the plugin, but for some reason I can't grok a few things. Here is my awesome plugin which resides in a file called Hello-World.js
import { converse } from "#converse/headless/core";
const plugin = {
initialize() {
console.error("Hello World!")
}
}
if (typeof converse === "undefined") {
window.addEventListener(
'converse-loaded',
() => converse.plugins.add("Hello-World", plugin)
);
} else {
converse.plugins.add("Hello-World", plugin);
}
The htpp-auth.js has no imports, but WebStorm was complaining that converse was unknown so I had to add the import. Why does the http-auth plugin not have to do that?
I am not sure where the plugin code is supposed to live. I added Hello-World under src/plugins/Hello-World. Is this correct?
Maybe related to above, but to get the plugin to actually run in addition to whitelisting it in my webpage I had to modify converse.js and add import "./plugins/Hello-World/Hello-World.js" which makes me think I am missing something obvious as I would think adding a plugin shouldn't require you to change the base code.
If it matters I am testing my plugin by running make serve in the conversejs directory and directing my web-browser (Chrome) to localhost:8000/fullscreen.html
Thanks, Wray

converse is available as a global once converse.js has been loaded via the <script> tag.
That's why there's the if (typeof converse === "undefined") { check at the end of the plugin. It waits for converse.js to be loaded if converse isn't yet defined.

Most community plugins are developed in such a way that they're loaded separately via <script> tags. If you do it like that, it doesn't matter where they live.

You can do it like that if you want to include your plugin inside a custom build of Converse, then you can also import stuff from converse.
The alternative is to load your plugin separately via a <script> tag, but then you can't import stuff and have to use the converse global and the closured _converse object that is passed to your plugin's initialize function.

I am hoping to confer on a strategy for a flutter web app (as can ignore mobile cases here) to get chrome extension info for a Polkadot.js wallet from the Polkadot browser extension.
My first thought is to use dart's JS library and use the Polkadot extension JS package and then try and pull the info from there. However, I'm not sure how to properly use this in flutter as it is a whole package full of dependencies, not just a single JS file. Also it is in TS not JS. Any thoughts here?
Eg., I need a JS file to be able to call this; and for flutter to in turn call the JS file:
import {
web3Enable,
} from '#polkadot/extension-dapp';
By writing out a "bridging" layer, you can do it easily.
Firstly, create a normal javascript (or typescript) application (nothing related to Flutter). You should be able to happily use the polkadot lib in your js/ts code without any problem. You may need to learn a bit about how to develop js code normally (e.g. you can depend on polkadot using npm, etc).
One small thing is that, you should "expose" some object publicly in your js/ts code. For example, your code may look like window.myFancyFunction = function() { call_some_polkadot_function(); }. Of course you can do more things like exposing other functions/objects/...
Then, you can bundle this normal js/ts application into a .js file. This is still very normal for js/ts developers and should have nothing special to deal with here, and you still do not need to touch Flutter at this stage.
Next, load this single-filed .js file when you are loading your Flutter Web application. You may simply do this by editing your Flutter Web's html file and add <script src="my_single_filed_js_mentioned_above.js" />. Notice that, when loading this script, it simply sets window.myFancyFunction and does not do anything more. Still very trivial here, should have no problem.
Lastly, in your Flutter Web code, i.e. Dart code, call that window.myFancyFunction function. For example, Flutter Web : How to run javascript using dart js says you can do import 'dart:js' as js; js.context.callMethod('myFancyFunction', ['some arguments']);
Im using the login example from the Meteor React Tutorial
meteor add accounts-ui accounts-password
Its all ok but Im trying to find the file and change it but I dont know where is it.
This is my code:
import { Blaze } from 'meteor/blaze';
export default class AccountsUIWrapper extends Component {
componentDidMount(){
this.view = Blaze.render(Template.loginButtons,
ReactDOM.findDOMNode(this.refs.container));
}
componentWillUnmount(){
Blaze.remove(this.view);
}
render(){
return <span ref="container"/>
}
}
And i have installed meteor add useraccounts:materialize
How can I put the template on this?
You need to put your component inside /imports/ui/ directory and name the file as AccountsUIWrapper.jsx
So it will be saved as /imports/ui/AccountsUIWrapper.jsx.
Then you can import your wrapped component inside /imports/ui/App.jsx file with:
import AccountsUIWrapper from './AccountsUIWrapper.jsx';
And then use it in your React render function in the same file as:
<AccountsUIWrapper />
The tutorial lays it out pretty clearly, including all the filenames and locations. You should be able to access their GitHub repository for the same.
If you want, for reference, you can also take a look at my code at this particular step back when when I did this tutorial myself.
Update: For useraccounts:materialize
The useraccounts:materialize package that you have mentioned depends on useraccounts:core package as its base. So you cannot apply useraccounts:materialize to default meteor accounts package directly.
Follow the instructions on useraccounts:core to set it up. You may need to remove accounts-ui as well, as it would likely clash with the above packages.
Then, go through the documentation for useraccounts that shows how to render their accounts template in Blaze.
After that, using the same way as shown in the tutorial, you should be able to create a new React wrapper for useraccounts:materialize Blaze template.
Here are links to boilerplate useraccounts:materialize code for Iron Router and Flow Router. From these you can take reference for the Blaze template code, which you can then wrap in React:

I have a project which is a mix of new code and old libraries, some of which is based on JQuery and JQuery plugins. I'm facing some issues where some plugins are using the global object ($) to integrate, and other are doing require("jquery") or the equivalent. This appears to be fetching two different instances of JQuery.
Because of some existing code, I need the global object to be there. However, to support my newer code I want anything that requires or imports 'jquery' to be provided the window.jQuery object instead of trying to load an external module.
Can I do this with SystemJS?
Did you try the SystemJS-Adapter-Modules? Create a file jquery.js and reference the globally loaded jQuery function:
module.exports = window.jQuery;
When you import "jquery" you should get a reference to the already loaded jQuery function.

I am looking for an example about combining the four technologies in the title :) I have a working ReactJS application using Play, Scala and WebJars, it's here on GitHub.
Now I would like to add RequireJS, but I'm not sure how to go, especially because it seems to require a different JSXTransformer? If anybody has a pointer (or even a PR) it would be very appreciated.
This is not the easiest thing to do, but I was able to pull it off. I will give you some tips here. I also uploaded my own project to github. This is a very simple snake game built using React and RequireJs. It based on Webjars and Play Framework.
Remember that RequireJs is part of Play Framework. Here's a step by step guide to create React/RequireJs/WebJars/Play integration:
In your plugins.sbt add addSbtPlugin("com.github.ddispaltro" % "sbt-reactjs" % "0.5.2"). This is a plugin which transforms JSXes into JSes and also strips flow types if you want that.
In your main scala.html file add #helper.requireJs(core = routes.WebJarAssets.at(WebJarAssets.locate("require.js")).url, module = routes.Assets.at("javascripts/main").url). This will add add a script tag with data-main and src attributes that are used to bootstrap your RequireJs app.
Create react.js file in your assets/javascripts folder:
define(['../lib/react/react-with-addons'], function(React) {
window.React = React;
return React;
});
Create main.jsx file in your assets/javascripts folder:
require.config({
// standard requirejs config here
});
require(['react', 'components/YourComponent'], function(React, YourComponent) {
'use strict';
$(document).ready(function() {
React.render(<YourComponent />, document.getElementById('container'));
});
});
Your standard React component goes to assets/javascripts/components/YourComponent.jsx and is defined like standard RequireJs module. Remember to return a React class:
define(function(require) {
var React = require('react');
var AnotherComponent = require('components/AnotherComponent');
return React.createClass({ ... });
}
I hope that helps. If you have any questions, please let me know.
Someone said to have got the text plugin working with sbt-rjs: https://groups.google.com/forum/#!topic/play-framework/F789ZzTOthc
I would attempt with the text plugin first, as it's the simplest plugin of all, right? Once this is successful, move on to the JSX plugin:
https://github.com/philix/jsx-requirejs-plugin
Have a look at: https://github.com/nemoo/democratizer
This is an example project that uses play framework, scala, slick, mysql as a restful backend.
The client is a javascript single page application (SPA) written in react. It uses react router for client site routing and ES6 javascript.
The build process combines webpack and play activator which enables simple automatic browser refresh for server and client side code.
I've working on a project and I'm using some jquery plugins, right now I'm trying to update my code to use backboje js but it's not clear how to put together those old plugins with backbone js.
the most important plugin I want to use is jcvl (http://code.google.com/p/jcvl/) but I'm trying to put this question general to get more ideas about how to integrate any pluggin with backbone.
Backbone only creates one global variable, Backbone, so there shouldn't be any conflicts with any jQuery plugins. Backbone also depends on Underscore.js, which also only creates one global variable, _, so it also shouldn't cause any conflicts. And if there is a conflict, both Backbone and Underscore.js offer you a noConflict() option.
I've been using Backbone with jQuery plugins for a while and haven't encountered any problems. You would use the plugin in the same way as before you introduced Backbone. For example:
var MyView = Backbone.View.extend({
render: function(){
$(this.el).html('<div class="foo"></div>');
this.$('.foo').somejQueryPlugin();
}
});
