I want to use moment.js library in my angular2-meteor application. For this, I installed the npm package with:
meteor npm install moment --save
Now, in the component, where I want to use this library, I have to import it somehow:
import {???} from 'moment';
But what must be imported here, so I can use it somewhere in the component in the following way:
var foo = moment().format('LLLL');
i have used moment in one of my angular2-meteor app. for using moment.js you should import it like this
import * as moment from 'moment';
and delcare it and use it like this.
current_year_header: any;
date: any;
this.date = moment();
this.current_year_header = this.date.format('YYYY');

I'm following along the guide to setup Meteor Tabular v2.1.2 (guide). I have added the package and installed the theming packages. I'm using Meteor v2.8.0 and the project is a Blaze-based project.
In client/main.js, I set up the library as instructed.
import { $ } from 'meteor/jquery';
import dataTablesBootstrap from 'datatables.net-bs';
import 'datatables.net-bs/css/dataTables.bootstrap.css';
import "../imports/ui/body";
dataTablesBootstrap(window, $);
Now when I go to the browser, there is this error:
Can anyone help me on this?
So after serious debugging , I discovered it is enough to just import the DataTable module as such after installing it with npm
import { $ } from 'meteor/jquery';
import 'datatables.net-bs';
import 'datatables.net-bs/css/dataTables.bootstrap.css';
import "../imports/ui/body";
// You don't need the code previously here .
You can now setup you DataTable as such
$(element).DataTable(//Your config object)
I want to import the firebase-database using esm import. I can only find the script version:
<script src="https://www.gstatic.com/firebasejs/7.21.0/firebase-database.js"></script>
What is the url I need for the esm module version?
Note: I do not want a "bare import", I am not using webpack etc. I need a complete url.
There is an older version available on unpkg.com but not the current version.
It turns out there are two CDN's that can provide this: snowpack/skypack, and jspm:
skypack:
import firebase from 'https://cdn.skypack.dev/#firebase/app'
import 'https://cdn.skypack.dev/#firebase/database'
jspm:
import { firebase } from 'https://jspm.dev/#firebase/app'
import 'https://jspm.dev/#firebase/database'
These both deal with "bare import" conversion to JS, and any code conversions required to be JS Modules.
Google does not appear to want to support a module form on their firebase CDN, an Issue to that effect was immediately closed, suggesting complex workflow solutions.
I'm really thankful to the two projects above, supporting simple es6 JS and zero workflow solutions.
Edit: snowpack's esinstall can turn most js files into modules. Here's a node script that brought in all my dependencies:
#!/usr/bin/env node --require esm
import { install } from 'esinstall'
import nodePolyfills from 'rollup-plugin-node-polyfills'
async function run() {
const foo = await install(
[
'mapbox-gl',
'three',
'three/examples/jsm/controls/OrbitControls.js',
'three/src/core/Object3D.js',
'chart.js',
'dat.gui',
'fflate',
'#turf/turf',
'stats.js',
'#firebase/app',
'#firebase/database',
],
{
rollup: {
plugins: [nodePolyfills()],
},
}
)
}
run()
If you're using a bundler, then follow the instructions in the documentation:
Install the firebase npm package and save it to your package.json file
by running:
npm install --save firebase
To include only specific Firebase products (like Authentication and
Cloud Firestore), import Firebase modules:
// Firebase App (the core Firebase SDK) is always required and must be listed first
import * as firebase from "firebase/app";
// If you enabled Analytics in your project, add the Firebase SDK for Analytics
import "firebase/analytics";
// Add the Firebase products that you want to use
import "firebase/auth";
import "firebase/firestore";
For realtime database, you would add import "firebase/database".
I downloaded the ChartJS package on Symfony, and I would like to be able to use it with webpack-encore
In my Twig template, I can use Chart with :
new Chart(document.getElementById("myChart"), { ..... }
It works with CDN, but now I would like to use it with webpack-encore.
So in my app.js I tried :
//1er essai
import Chart from "chart.js";
global.Chart = Chart
//2eme essai
const Chart = require("chart.js");
global.Chart = Chart;
But neither works. Each time in the browser I get the following error :
Uncaught ReferenceError: Chart is not defined
Can someone help me please ?
When using webpack encore I find it easier to install different modules via npm.
In the documentation it says that bower and npm are recommended.
So you basically write this
npm install chart.js --save
And for usage you simply import it.
If you use Yarn (recommended by Webpack Encore), just type :
yarn add chart.js
Then in your js file :
import Chart from 'chart.js';
new Chart($("#myElement"), {
...
});
I'm trying to use the firebase in a react native project
I installed the firebase in my project:
npm install --save firebase
and I'm importing it into my app.js
import firebase from 'firebase';
import React, { Component } from 'react';
import {
Platform,
Text,
View
} from 'react-native';
type Props = {};
export default class App extends Component<Props> {
render() {
return (
<View >
<Text>Testando Firebase</Text>
</View>
);
}
}
and then the error is displayed:
Objects are not valida as a react child (found: object with
keys{&&typeof, type, key, ref, props, _owner, _store}). If you meant
to render a collection of children, use an array instead.
but when I remove the import from firebase, the app works perfectly.
Try to install the version 5.0.2. Use this command as administrator:
npm uninstall firebase
npm install --save firebase#5.0.2
As far as i see, the current version (5.0.4) is buggy!
You need to import as follow
import * as firebase from 'firebase';
You first must have firebase installed.
The solution is to uninstall the current version of Firebase and install an older version.
1st step npm uninstall firebase
2nd step npm i firebase#8.0.3
It was the version that worked for my case.
I would like to know how to use React components from npm in Meteor 1.3 using import.
I am trying to use react-gravatar in my project. I did npm install --save react-gravatar. And in my component, I required it:
import React from 'react';
import Gravatar from 'react-gravatar';
export default React.createClass({
render() {
...
}
});
But I get:
Uncaught Error: Cannot find module 'querystring'
I think this is because querystring is not available in client side, and I need to use browserify-reactify of some sort. But how can I do so in Meteor 1.3?
