vmsg requires a URL link to a .wasm file that it requires in order to work. Their sample code (which does work) looks as follows:
import React, { Component } from 'react';
import vmsg from 'vmsg';
const test = new vmsg.Recorder({wasmURL: "https://unpkg.com/vmsg#0.3.0/vmsg.wasm"});
But I would like to have that file refer to a directory in my app rather than this external URL and I'm not certain:
Where I should place this file (assets/public/node_modules folder)?
What I would do to make this work (do I do an import or do I reference it directly somehow)?
I've tried placing the file in my assets folder and changing the line of code to many things along the lines of:
const test = new vmsg.Recorder({wasmURL: '../../assets/vmsg.wasm'});
But nothing seems to be working, which, after some reading, makes sense. But I'm still not sure what the right way to add a file like this should be instead.
I've seen some people run into something like this specifically when trying to import photo assets. One solution that I've found to work for that is to include .default at the end.
const test = new vsmg.Recorder({wasmURL: require('../../assets/vmsg.wasm').default});
Let's say I have a couple translation files like so:
import English from "./lang/compiled-en.json";
import Spanish from "./lang/compiled-es.json";
and so on for all the languages we plan to support. These are imported directly into the component they are used, and our app as a whole is split into chunks with webpack that may contain many components and thus, many strings.
It would be ideal to only be importing the languages.json file I need depending on the user's locale, and not import all of them while having to check the locale and using only one.
I tried a super naive stab at it here, but it certainly does it work:
Helper function existing in another directory:
export async function loadLocaleData(locale: string, path: string ) {
switch (locale) {
case "en-US":
return await import(path + "/lang/en-compiled.json");
case "pt-BR":
return await import(path + "/lang/pt-br-compiled.json");
default:
return await import(path + "/lang/en-compiled/en.json");
}
}
I was thinking that importing this helper function into my components that need translations would look in their own directory for the translation file. But even when I have that path hardcoded to specify exactly where the translation file is, I still get errors.
The above may be implemented into a component like so:
const localeContext = useContext(LocaleContext);
const messages = loadLocaleData(
localeContext.locale,
"packages/components/Preferences/Billing"
);
And then I'd ideally pass just that message into my IntlProvider that wraps this individual component.
This definitely isn't working. Is there a way to make it work? I know what I want to do, I'm just not sure how possible it is.
You can use dynamic imports like you are trying, but you need to use absolute paths. Otherwise your bundler (Webpack) won't actually know where to find them.
Alternatively, store your language files in your public/ directory and use the public path to it. Webpack won't touch those files (besides index.html) and might be your best option here.
I am getting the below error on a page that is stopping it being rendered and after checking other similar errors I have double checked the import is correct and the node_modules react index file is installed.
What else could be causing this? I have had linting issues yesterday out of nowhere that I thought had fixed themselves.
The file this refers to should be node_modules/React/react.indexjs but on my system is node_modules/react.index.js. I haven't changed this myself so i'm not sure where it has come from. I have also removed any code that was added to this file which could of been causing it.
Cannot find file: 'index.js' does not match the corresponding name on disk: '.\node_modules\React\react'
This happens when you import react like this
import React from "React"
notice the capital R
instead, you should do :
import React from "react"
( with a small r )
This happens due to case sensitivity. Check if the file name is exactly the same in the same case.
Eg:
Cannot find file: 'CheckBox.js'
Check if the filename is exactly CheckBox.js not Checkbox.js
try creating the index.js in the src folder, i'm sure you created it outside the src folder.
I have a problem, already solved it, but make me confuse about modules.
I tried to import an Animated in my component.
import { Animated, Easing } from 'react-native';
and then, I tried to find Its type (flow), I found that answer in.
Flow types for react-native's Animated library (Thank you).
import type AnimatedValue from 'react-native/Libraries/Animated/src/nodes/AnimatedValue';
The question is.
When I open Animated in import { Animated, Easing } from 'react-native';(right click, then I go to type definition with "Visual code"), Why it doesn't go to Its module, but to this path? (Library/Caches)
I tried to find out this file (index.d.ts) in "react-native" modules, but I cant find it. Why?
Then I try to read index.d.ts, to find out type for Animated.Value.
export namespace Animated {
type AnimatedValue = Value;
type AnimatedValueXY = ValueXY;
export class Value extends AnimatedWithChildren {
Horraay, I got Animated.Value is a class, and Its type is an AnimatedValue. Then as usual to find Its path, I right click, then I go to type definition with "Visual code", but I found nothing.
So, how can this import type AnimatedValue from 'react-native/Libraries/Animated/src/nodes/AnimatedValue relate to type AnimatedValue = Value; in index.d.ts?
"react-native": "0.63.2",
index.d.ts files are used to provide typescript type information about a module that's already written in JavaScript. This will allow you to use the javascript modules without the need to first convert them completely to ts without getting any type error on your code.
Why it doesn't go to Its module, but to this path?
It's because when you install types for particular library using npm, they get installed under node_modules/#types/<library-name>/ location as index.d.ts file. Therefore using VSCode's navigate to type definition feature takes you to this index.d.ts file instead of taking you within library.
I tried to find out this file (index.d.ts) in "react-native" modules,
but I cant find it. Why?
All index.d.ts files are stored at node_modules/#types/<library-name> not at node_modules/<library-name>. As a result you can't finid these files in corresponding modules.
I was attempting to make a "library" type of project in dart and then "depend" on that library from another project (all using the path dependency functionality of the yaml file). I understand that I might be able to get the dependency stuff to work if I hosted my library or if I used GIT, but I don't want to do either, because I feel that pure filesystem based dependencies should be a "no brainer".
So, without further adieu, here is my situation. I have a very simple dart library/project based on web_ui that contains two files:
esrvdartui.dart
---------------
library esrvdartui;
import 'dart:html';
import 'package:web_ui/web_ui.dart';
part 'esrvradiobutton.dart';
esrvradiobutton.dart
--------------------
part of esrvdartui;
class ESrvRadioButton extends RadioButtonInputElement
{
ESrvRadioButton ()
{
}
}
I then created another very small/simple web_ui based project called "ExampleForm" that wants to use my esrvdartui project above. Both of these projects exist in the same directory structure. My ExampleForm project contains the following yaml file:
pubspec.yaml
------------
name: ExampleForm
description: A sample WebUI application
dependencies:
js: any
browser: any
web_ui: any
esrvdartui:
path: ../esrvdartui
No matter what I set my path to in the above yaml file, I never see my web\packages directory underneath of my ExampleForm project get updated with my files from the esrvdartui project and as such, I cannot use the files in my library using the file based dependency method, because the build fails for my ExampleForm project.
"Pub install" does not complain with the above path and it doesn't complain when I use an absolute path, so I know that "Pub install" see my dependent project. It just doesn't copy the darned files for me.
Any thoughts?
My pubspec.lock file for ExampleForm is:
# Generated by pub

I finally got this to work, but for the life of me, I couldn't find this documented anywhere. All you have to do is create a project in the Dart IDE. Then, create a top level folder in that project called "lib" (blow all other directories away other than the top level "packages" folder). Now, create your main library's .dart file. Let's call it "mylibrary.dart". This contents of this file will look something like this:
mylibrary.dart
library mylibrary;
import 'dart:json';
part 'src/libraryfile1.dart';
Now, create a sub-directory underneath of "lib" to place your library's source files into. This can really be named anything, but I choose to name it "src". Place your libraryfile1.dart file there and it should look something like this:
src/libraryfile1.dart
part of hix_lib;
.
.
.
All import statements should always be placed in your top-level main library file: mylibrary.dart.
Now, in the project that you wish to use this file-based library in, you must add your "mylibrary" to your project's pubspec.yaml file and choose: "Source: path". On my machine, because all projects are in the same directory, my path simply points to: ../mylibrary
And that's all there is to do!!!!!
