CanJS with StealJS 0.3.0 - canjs

I am playing around on an app with canjs 2.1.0 and stealjs 0.3.0:
I have stealconfig.js like below:
System.config({
map: {
"can/util/util": "can/util/jquery/jquery",
"jquery/jquery": "jquery"
},
paths: {
"jquery": "bower_components/jquery/dist/jquery.js",
"can/*": "bower_components/canjs/*.js",
"lodash": "bower_components/lodash/dist/lodash.js",
"bootstrap" : "bower_components/bootstrap/dist/js/bootstrap.js",
"bootstrap.css" : "bower_components/bootstrap/dist/css/bootstrap.csscss"
},
meta: {
jquery: {
exports: "jQuery",
deps: supportsUnknownElements ? undefined : ["can/lib/html5shiv.js"]
}
},
ext: {
mustache: "can/view/mustache/system"
}
});
And my main.js is:
import can from 'can/';
import $ from 'jquery';
import _ from 'lodash';
import LayoutController from 'apps/layout/layout';
can.route.ready();
new LayoutController(document.body, {});
layout .js loos like:
(function() {
'use strict';
var can = require('can/'),
layoutView = require('./view/layout.mustache!');
})();
But, I get these errors.
GET http://localhost:8080/bower_components/canjs/can.js 404 (Not Found)
GET http://localhost:8080/bower_components/canjs/view/mustache/system.js 404 (Not Found)
How can I solve this issue?

To use CanJS with the new Steal you need to be using the minor branch of CanJS. There hasn't been a tag release yet that supports the new version of Steal.
You can do this easily with bower, just like this (in your dependencies):
"canjs": "bitovi/canjs#minor"
Other comments:
1) When you're using CommonJS (as you are in layout.js) you don't need to wrap it in an self-calling function. That will be done by Steal.
2) The error suggests it cannot find the file. Are you certain you have ran "bower install" to install CanJS? Your configuration looks fine.

Error: Step implementation missing for: [step_definition] when trying to run a scenario using cucumber with cypress 10

I have updated my project to cypress 10. But getting this error couldn't solve the problem described in the title.

Unresolved dependencies & Missing global variable name when trying to import #mapbox/mapbox-gl-geocoder

I'm beginning with Svelte and I would like to (more or less) reproduce Mapbox store locator tutorial with Svelte & rollup. (Starting from svelte REPL starter kit).
Everything's fine for loading a map and some markers, but as soon as I try to import this package https://github.com/mapbox/mapbox-gl-geocoder, nothing works anymore and I'm not familiar enough with Svelte to figure out how to setup rollup and fix it.
<script>
import { onMount, setContext } from 'svelte'
import mapbox from 'mapbox-gl/dist/mapbox-gl.js';
import MapboxGeocoder from '#mapbox/mapbox-gl-geocoder'; // <<--- Problem here
mapbox.accessToken = 'xxx';
let map;
let geocoder;
onMount(() => {
map = new mapbox.Map({,,,});
geocoder = new MapboxGeocoder({,,,});
});
</script>
terminal :

declaring namespacesRequired array on page-level component

I've got a project based on next and react, using i18next package I encounter the following warning which I think is the reason why it takes plenty of time to load i18n according to react profiler:
You have not declared a namespacesRequired array on your page-level
component: withI18nextTranslation(Error). This will cause all
namespaces to be sent down to the client, possibly negatively
impacting the performance of your app. For more info, see:
https://github.com/isaachinman/next-i18next#4-declaring-namespace-dependencies
notes : The translation works fine, I have declared namespacesRequierd in all of my components except 404.
this is my i18n config :
const NextI18Next = require('next-i18next').default
const { localeSubpaths } = require('next/config').default().publicRuntimeConfig
const path = require('path');
module.exports = new NextI18Next({
preload: ['fa'],
defaultLanguage: 'fa',
otherLanguages: ['en','ar'],
localeSubpaths,
localePath: path.resolve('./public/static/locales'),
localeStructure: '{{lng}}/{{ns}}',
fallbackLng: 'fa',
ignoreRoutes:['/_next/', '/static/', '/public/', '/api/'],
serverLanguageDetection: false,
defaultNS: 'common',
localeExtension: 'json'
});
next.config.js :
const { nextI18NextRewrites } = require('next-i18next/rewrites');
rewrites: async () => nextI18NextRewrites(localeSubpaths),
publicRuntimeConfig: {
localeSubpaths
}
versions :
package.json :
"i18next": "^19.7.0"
yarn :
next-i18next#^6.0.2:
version "6.0.2"
dependencies:
"#types/express" "^4.16.1"
core-js "^3"
hoist-non-react-statics "^3.2.0"
i18next "^19.6.3"
i18next-browser-languagedetector "^5.0.0"
i18next-fs-backend "^1.0.7"
i18next-http-backend "^1.0.17"

path-match "^1.2.4"
prop-types "^15.6.2"
react-i18next "^11.7.0"
url "^0.11.0"
there's nothing related to this in my server.js file.

Getting svelte-material-ui working with snowpack and sass

I'm trying to get svelte material UI working with snowpack.
I have installed Snowpack and Snowpacks svelte template like so:
npm install --save-dev snowpack#next
npx create-snowpack-app xpapp --template #snowpack/app-template-svelte
This works, the sample svelte page shows up. Next I followed the Svelte Material UI instructions to "bundle this in your own code" as cited on the Usage chapter in the instructions here: https://github.com/hperrin/svelte-material-ui#usage
So I installed Sass and configured it in my snowpack.config.json file like this:
{
"extends": "#snowpack/app-scripts-svelte",
"scripts": {
"build:scss": "sass"
},
"devOptions": {},
"installOptions": {}
}
I followed the (very concise) instructions here: https://www.snowpack.dev/#sass
I've also added an empty src/theme/_smui-theme.scss file to my source files as the instructions say, and I installed the nessecary #smui components.
The problem is that I'm currently getting this error when starting the snowpack dev server:
> snowpack dev
Snowpack Dev Server (Beta)
NOTE: Still experimental, default behavior may change.

It seems that the #import statements in Material UI's _index.scss aren't recognized. I figure Snowpack should interpret/transpile .scss files, but it doesn't seem to be doing that.
So I came across the same problem using Svite as well as Snowpack. I was able to use the bare implementation:
// component.svelte <script>
import Button, { Label } from '#smui/button/bare'
import '#smui/button/bare.css'
That's all that's required with Svite.
With Snowpack, I needed to add rollup-plugin-svelte and update snowpack.config.js
// snowpack.config.js
module.exports = {
// ...
installOptions: {
rollup: { plugins: [require('rollup-plugin-svelte')()] }
},
// ...
}
I got it working with these install options:
installOptions: {
rollup: {
plugins: [
require("rollup-plugin-svelte")({
include: ["./node_modules"],
}),
require("rollup-plugin-postcss")({
use: [
[
"sass",
{
includePaths: ["./src/theme", "./node_modules"],
},
],
],
}),
],
},
},
Unfortunately, you'll have to run npx snowpack dev --reload for changes to the theme to take effect.
This won't extract css into .css files.
I also got an error message with the Dialog component during a production build.
Here is a full example: https://github.com/LeanderG/svelte-smui

Loading D3 with Nuxt/Vue

I am trying to implement D3 in an app I am building with Nuxt. I have successfully imported it into a view in the <script> section with import * as d3 from 'd3' however because the app is being rendered server-side D3's functionality doesn't work (i.e. d3.select(...)) due to the lack of browser. In the Nuxt plugin documentation it suggests a pattern for client-only external plugins:
module.exports = {
plugins: [
{ src: '~plugins/vue-notifications', ssr: false }
]
}
I attempted to implement the pattern in the nuxt.config.js of my project:
module.exports = {
head: {
title: 'My Demo App',
meta: [...],
link: [...]
},
loading: {...},
plugins: [
{ src: '~node_modules/d3/build/d3.js', ssr: false}
]
}
However D3 throws a ReferenceError while looking for document and Nuxt throws a SyntaxError in the console pointing to something in the plugins field of nuxt.config.js.
For reference, demo.vue:
<template>
<div class="demo-container"></div>
</template>
<script>
import * as d3 from 'd3';
d3.select('.demo-container');
</script>
Would someone be able to point to what I'm doing wrong?
For anyone coming to this page looking for a solution,
these suggestions from piyushchauhan2011 here on GitHub sent me in the right direction.
All I needed to do:
import d3 in my single-file component, and then
do any DOM manipulation with d3 only within mounted()
Before all this, I had to of course add d3 to my project with yarn add d3 (or npm install d3).
[Edit: removed link that no longer works. It wasn't that relevant anyway.]
I was getting an error:
Must use import to load ES Module: .../node_modules/d3/src/index.js require() of ES modules is not supported. require() of .../node_modules/d3/src/index.js from .../node_modules/vue-server-renderer/build.dev.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules. Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from .../node_modules/d3/package.json.
I solved it by reading this: https://github.com/nuxt/nuxt.js/issues/9223
which indicates you can add this to your nuxt.config.js file:
build: {
standalone: true,
}
This allowed the d3 import to work.
import * as d3 from "d3";
Here's a simple step-by-step tutorial:
Create a new NuxtJS project (Skip this step if you have an existing project)
npm init nuxt-app nuxtjs-d3js-example
Install D3JS
npm install d3
npm install #types/d3 --save-dev
Import D3JS and add a target
HTML:
<p id="d3-target"></p>
JavaScript:
import * as d3 from 'd3'
export default {
name: 'NuxtTutorial',
mounted: function() {
d3.select("#d3-target").text("This text is manipulated by d3.js")
},
}
Fix ES Module error (mentioned by #agm1984)
Error:
require() of ES Module /home/johnson/projects/nuxtjs-d3js-example/nuxtjs-d3js-example/node_modules/d3/src/index.js from /home/johnson/projects/nuxtjs-d3js-example/nuxtjs-d3js-example/node_modules/vue-server-renderer/build.dev.js not supported. Instead change the require of index.js in /home/johnson/projects/nuxtjs-d3js-example/nuxtjs-d3js-example/node_modules/vue-server-renderer/build.dev.js to a dynamic import() which is available in all CommonJS modules.
nuxt.config.js:
build: {
standalone: true,
}
