I can't figure out how to import html files with webpack 2! I am using angular 1.6.0 and typescript.
I would like to import a template and use it as a router state template:
import * as angular from 'angular';
import * as uiRouter from 'angular-ui-router';
import theView from './theView.html';
import appComp from './app.component';
export default angular
.module('app.main', [uiRouter])
.component('myAppComp', appComp)
.config(($stateProvider, $urlRouterProvider, $locationProvider) => {
'ngInject';
$locationProvider.hashPrefix('');
$stateProvider
.state('main', {
url: '/main',
template: '<p>main state template</p>'
})
.state('main.cardList', {
url: '/cardList',
template: theView
});
}
It gives:
error:
ERROR in ./src/app/module.ts
(3,22): error TS2307: Cannot find module './theView.html'.
What (wierd) I don't understand is if I import the template same as above and use it in a component template, it does gives same error "cannot find module './theView.html'" but it works!
This works (with ts compilation error):
import template from './theView.html';
.component(appComp, {
template
})
webpack.config:
module.exports = {
entry: './src/app/module.ts',
module: {
rules: [
{
test: /\.tsx?$/,
loader: 'ts-loader',
exclude: /node_modules/
},
{
test: /\.html$/,
use: [{ loader: 'html-loader' }]
}
]
},
output: {
filename: 'bundle.js',
path: __dirname + "/dist"
}
};
What is going on here..?
For the people who can come across this problem in the future; it is solved as follows:
declare const require: any;
$stateProvider
.state('main.cardList', {
url: '/cardList',
template: require('./theView.html').default
});

Here: https://stackblitz.com/edit/partehoras?file=src/app/app.module.ts
When I add App Roting like I do it in my VS Code local project without any problem
In package.json
I get this error: "Error in src/app/app.module.ts (5:34)
Cannot find module './app-routing.module' or its corresponding type declarations."
Any idea, please?
Thanks
You already have RouterModule.forRoot([]) imported in the app module, I am assuming you want to move to a separate file, if so, you need to create a file in the same folder as the app module with the name app-routing.module.ts and add the following code
import { RouterModule, Routes } from '#angular/router';
import { ListadoEmpleadosComponent } from './empleados/listado-empleados/listado-empleados.component';
import { NgModule } from '#angular/core';
export const routes: Routes = [
{ path: 'empleados', component: ListadoEmpleadosComponent },
{ path: '', redirectTo: 'empleados', pathMatch: 'full' },
{ path: '**', redirectTo: 'empleados', pathMatch: 'full' },
];
#NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule],
})
export class AppRoutingModule {}
P.S. if you generate an angular app using the angular CLI you will get a prompt to create app routing module which will create the file automatically.
I have a file structure like so app(main) and dashboard(secondary) being the different pages
but when trying to open the secondary app at /
vite.config.js
import * as path from "path";
import { defineConfig } from "vite";
import react from "vite-preset-react";
import svgr from 'vite-plugin-svgr'
import rollupReplace from "#rollup/plugin-replace";
const outDir = path.resolve(__dirname, 'build')
export default defineConfig({
plugins: [
rollupReplace({
preventAssignment: true,
values: {
__DEV__: JSON.stringify(true),
"process.env.NODE_ENV": JSON.stringify("development")
}
}),
react(),
svgr()
],
root: 'app',
build: {
root: outDir,
rollupOptions: {
input: {
app: path.resolve(__dirname, "app/index.html"),
dashboard: path.resolve(__dirname, "dashboard/index.html"),
}
}
},
});
and the server.js file is just an empty file not used
I have a problem with images importing using vanilla-extract and esbuild
my build file:
const { build } = require("esbuild");
const { vanillaExtractPlugin } = require("#vanilla-extract/esbuild-plugin");
(async () => {
await build({
entryPoints: ["src/entry.tsx"],
bundle: true,
minify: true,
sourcemap: true,
platform: "browser",
outfile: "dist/entry.js",
plugins: [vanillaExtractPlugin()],
loader: {
".svg": "file",
},
});
})();
my entry.tsx
import { someStyle } from "./style.css";
console.log(someStyle);
When i importing my image in "css" way
import { style } from "#vanilla-extract/css";
export const someStyle = style({
backgroundColor: "url(./x.svg)",
});
The compiler return error
Could not resolve "./x.svg" (the plugin "vanilla-extract" didn't set a resolve directory)`
If i am trying to import x.svg using the typescript import
import { style } from "#vanilla-extract/css";
import svg from "./x.svg";
export const someStyle = style({
backgroundColor: `url(${svg})`,
});
I have other error
src/style.css.ts:5:16: error: No loader is configured for ".svg" files: src/x.svg'
Is it possible to import images with vanilla-extract modules without marking them as external?
It not working now. Workaround is to use babel
import babel from 'esbuild-plugin-babel';
plugins: [
babel({
filter: /.*.css.ts/,
config: {
presets: ['#babel/preset-typescript'],
plugins: ['#vanilla-extract/babel-plugin'],
},
}),
],
Running webpacker 3.5.5 (both the gem and package). This is mostly working, but in IE11 the app is broken because arrow functions do not appear to be transformed. However, inspecting the minified code it seems like the only place arrow functions aren't transformed are inside my vue components.
I think this is because my babel class properties plugin is not applying to my Vue loader somehow, but I haven't been able to come up with a solution.
Here's my .babelrc
{
"presets": [
[
"env",
{
"modules": false,
"targets": {
"browsers": [
"> 1%",
"IE 11"
],
"uglify": true
},
"useBuiltIns": true
}
]
],
"plugins": [
"syntax-dynamic-import",
"transform-object-rest-spread",
[
"transform-class-properties",
{
"spec": true
}
]
],
"env": {
"test": {
"presets": ["es2015"]
}
}
}
And here's the entirety of my environment.js file that modifies the webpack environment that webpacker ships with (vue loader is at the bottom).
const { environment } = require('#rails/webpacker');
environment.loaders.append('expose', {
test: require.resolve('jquery'),
use: [{
loader: 'expose-loader',
options: 'jQuery'
}]
});
const webpack = require('webpack');
// append some global plugins
environment.plugins.append('Provide', new webpack.ProvidePlugin({
$: 'jquery',
jQuery: 'jquery',
axios: 'axios',
moment: 'moment-timezone',
_: 'lodash'
}));
// Necesary configuration for vue-loader v15
const VueLoaderPlugin = require('vue-loader/lib/plugin');
environment.plugins.append(
'VueLoaderPlugin',
new VueLoaderPlugin()
);
environment.loaders.append('vue', {
test: /\.vue$/,
loader: 'vue-loader'
});
module.exports = environment;
Edit for more info: Here is the entry point to my pack called 'wrestling'
import 'babel-polyfill';
import 'wrestling';
Then in wrestling.js...
import './styles/wrestling'
import Rails from 'rails-ujs'
Rails.start();
import wrestlingSetup from './wrestlingSetup'
wrestlingSetup();
WrestlingSetup contains the actual references to the vue files. I've cut down the file to show what a single vue import looks like within the file. All the rest are essentially the same.
import Vue from 'vue/dist/vue.esm'
// Redacted a bunch of imports, but they all look like this oen
import WrestlerCreate from './vue/wrestler_create.vue'
export default function() {
document.addEventListener('DOMContentLoaded', () => {
axiosSetup();
const app = new Vue({
el: '#app',
components: {
// Other vue components here that I've removed for simplicity
WrestlerCreate,
}
})
});
}
Here's an actual example of the Vue component
<template>
<div role="form">
<!-- other form elements -->
</div>
</template>
<script>
export default {
name: 'wrestler-create',
props: [
],
// This does not get transformed by babel
data() {
return {
loading: false,
error: false,
errorMessage: "Error, please try again later or contact support.",
first_name: '',
last_name: '',
weight_class: '',
academic_class: ''
}
},
methods: {
// removed for simplicity
}
}
</script>
For clarify sake:
Please use function() for data. I find function() gives me less trouble than arrow functions.
export default {
data: function() {
return {
message: "Hello something!",
secondMessage: "Hello world!"
};
}
}
If you really wish to use arrow function, you can write:
export default {
data: () => {
return {
message: "Hello something!",
secondMessage: "Hello world!"
};
}
}
My team updated the Rails version of our application to 5.1 so we could use Webpacker, a wrapper to use Webpack with Rails and then use Angular 2 properly.
We started setting up the test suite for the Angular 2 modules using Karma + Jasmine + Webpack following this article.
If I write simple test cases, without Angular Component, TestBed and ComponentFixture, everything looks fine. However, if I try to import Angular modules and test some components, Karma raises the following error message for every component and module:
ERROR in ./app/javascript/app/app.module.ts
Module parse failed: /[application path omitted]/app/javascript/app/app.module.ts Unexpected character '#' (17:0)
You may need an appropriate loader to handle this file type.
