Hi I am using NuxtJS to build a VueJS application. I have installed an image cropping library vue-croppie. I have imported the Vue component as per the documentation like below
import VueCroppie from 'vue-croppie'
However, I am getting the following error on import statement
Could not find a declaration file for module 'vue-croppie'. 'xxx/node_modules/vue-croppie/dist/vue-croppie.cjs.js' implicitly has an 'any' type.
Try npm i --save-dev #types/vue-croppie if it exists or add a new declaration (.d.ts) file containing `declare module 'vue-croppie';
I have tried declaring index.d.ts file at the root of my project with following content but id doesn't solve the problem
declare module 'vue-croppie';
I have tried using require like below as suggested on other posts but of no use
const VueCroppie = require('vue-croppie')
I understand this is a Typescript issue but have no knowledge about Typescript. Can somebody throw more light on this. What is happening and how to fix it.
Thanks
The issue was I had not installed the plugin with VueJS app. Here is how to do it.
VueJS
We can use Vue.use to isntall a plugin before it can be used like below
import Vue from 'vue';
import VueCroppie from 'vue-croppie';
Vue.use(VueCroppie)
NuxtJS
In case of NuxtJS it is little different. The plugin is registered globally, here's how.
Create a file called vue-croppie.js under plugin folder. And add the following to it
import Vue from 'vue'
import VueCroppie from 'vue-croppie'
Vue.use(VueCroppie)
In your nuxt.config.js add this under plugins
{ src: '~/plugins/vue-croppie.js', ssr: false }
Now, the plugin will be available globally. So there is no need to import and can be used directly.

GOAL
I am trying to setup Typescript, Vue, and Vuetify in Codesandbox, but it seems like nothing will cooperate.
I copied code straight from a normal Vue app initialized with Vue CLI and it doesn't work :/
PROBLEM
Typescript will not recognize .vue files (such as import App from "#/App.vue"; in main.ts)
In App.vue, eslint keeps flagging # from the #Component decorator EVEN though I set a parser in .eslintrc.js
ATTEMPTED SOLUTIONS
I tried to solve the problem with Typescript not recognizing .vue files using Importing Vue components in TypeScript file
BUT it doesn't work anymore. Also, this implementation makes every import hyperlink go to vue-shim.d.ts. When I CNTRL click the import to go to the imported file's contents, I go to vue-shim.d.ts instead of to the imported file.
I tried solving the #Component decorator problem with eslint using ESLint unexpected character '#' for JS decorators
BUT it did nothing.
CODE
https://codesandbox.io/s/infallible-framework-pjbx1?file=/src/App.vue
I'm starting out using vue.js in a real django project, but I'm already encountering an issue.
I've installed npm in the venv environment, and installed the vue package.
I now want to create a Vue object inside a js file, so I use :
import Vue from 'vue'
But in the console I get this error
Uncaught SyntaxError: Cannot use import statement outside a module
I've searched for this issue but couldn't find a good answer for my specific case.
How to proceed to use vue js via the npm package then ?
I'm pretty sure the better, but much harder approach is getting webpack and babel involved. However, for my small project, that seemed overkill. I made the node_modules directory visible to staticfiles finder:
STATICFILES_DIRS = (
os.path.join(BASE_DIR, "node_modules"),
)
Now I had to access them thru the STATIC_URL (for me it is "/static/").
import Vue from 'static/dist/vue/vue.js'
Right now I pull in all my own es6 modules and create a bundle using Rollup.
Recently I started using VueJS, which now has an ES6 Module which can be pulled in just like my own modules. Rollup does some treeshaking on it, but I don't know if that is a very good idea? I don't know what it is doing, so I would rather it does nothing!
Instead I just add vue at the end of my HTML:
<script src="dist/bundle.js"></script>
I love the convenience of having everything as one bundled file, but should I really treeshake the entire Vue app, is there a command in Rollup that I can not treeshake just this one module?
EDIT
I have found the --external option, which seems good as it would just keep the import for vue and bundle the rest, but it does not seem to work!
When I use rollup --format=iife --external=../node_modules/vue/dist/vue.esm.browser.js --file=dist/bundle.js -- src/main.js it says Error: Could not resolve '../node_modules/vue/dist/vue.esm.browser.js' from src/app.js.
In my main.js it has import Vue from '../node_modules/vue/dist/vue.esm.browser.js; which works fine for the app. I want to make Vue an external, but it won't work!
To prevent Rollup from treeshaking a particular module, you can simply import it blindly (instead of a part of it), so that Rollup thinks the module performs some side effect:
import 'vue'
Of course you can still import some bits in parallel, so that you can rename the default export for example:
import 'vue'
import Vue from 'vue'
As for your --external option, you probably just need to wrap the path value with quotes:
--external='../node_modules/vue/dist/vue.esm.browser.js'
Note that you should probably switch to Rollup configuration file (instead of CLI options) to make your life easier. You will also be able to use rollup plugins, e.g. rollup-plugin-alias to manage the exact location of the Vue file you want to use.
Context
I'm working on a project using Angular2, TS and SystemJS. I've built a simple module loader using SystemJS which allows me to import 'custom' modules like this :
import { NavComponent } from "component#nav";
Maybe it'll be important.
Goal
I would like to import .scss files inside my angular components to be able to do things like that :
#Component({
selector: 'app-view',
styles: [ require('path/to/mainScss/file.scss') ],
template: //...
})
Issue
I've found some examples using webpack but I can't get this works. During searching, I've found this module. It can be interesting because it uses SystemJS like me and I don't have to add webpack to my project.
So I've decided to use it (and I'm not sure if it's possible to use webpack and SystemJS at the same time. require was undefined). I didn't know jspm before using this module, I've always used npm. So I've installed jspm locally (relative to my project) and globally and I've installed the module.
Then, inside a component : import './styles/importer.scss!';. And I get an error here.
Error: SyntaxError: Unexpected token <. I know that this error happens when SystemJS failed to load a module but I can't figure out why.
Why ?!
Why am I trying to do that ?
My module loader allows me to write some modules in separate folders (named like this namepace#name). I can add those folders inside another one named modules/ and then enable/disable modules by editing a configuration file.
So I want my .scss files to be loaded only if a module is enabled. That's why I want to include my sass inside an Angular component. That way, it'll be loaded only if the component is loaded.
I looked at this and that link. I bower installed file-saver and Blob. I am having a similar problem with both components so I will just talk about one.
When I do import FileSaver from 'file-saver';
I get the following error.
Error while processing route: some.route Could not find module `file-saver` imported from `client/pods/some/folder/controller` Error: Could not find module `file-saver` imported from `client/pods/some/folder/controller`
I know the I have file-save because it is in my bower_components folder.
And right about the line that is giving me trouble is the following line.
import Ember from 'ember';
that package is about the file-saver package in my bower_components folder. And the app seems to find that package.
Bower assets have to be imported in Brocfile.js, see http://www.ember-cli.com/#managing-dependencies
In my project, filesaver is located at bower_components/FileSaver.js/FileSaver.js, so I have the following line in my Brocfile.js:
app.import('bower_components/FileSaver.js/FileSaver.js');
This makes it available as a global on window.saveAs, no need to use an import statement in the file you use it in.
