I have been trying to make custom component in Adminjs 6.6.5 dashboard but Adminjs ComponentLoader not found error occurs. then i have tried to
import AdminJS from 'adminjs'
const {ComponentLoader} = AdminJS
but i get: Trying to bundle file 'file:/Users/Josip/WebstormProjects/ferry-backend/components/dashboard.jsx' but it doesn't exist
I would really appreciate help...
admin/index.js
import {ComponentLoader} from "adminjs";
const componentLoader = new ComponentLoader()
const Components = {
MyDashboard: componentLoader.override('Dashboard','../components/dashboard.jsx')
}
export { componentLoader, Components }
index.js
import {componentLoader, Components} from "./admin/index.js";
AdminJS.registerAdapter(AdminJSSequelize)
const admin = new AdminJS({
databases: [],
rootPath: '/admin',
resources:[UsersResources, GuestResources, SalesResources, FinancesResources],
components:{
edit: Components.MyDashboard
},
componentLoader
})
you are fixed this problem? I also ran into this problem and don't understand how to solve it
i fixed this problem. You need to do the import as follows
import AdminJs from 'adminjs';
// And now you can use any adminjs dependencies as follows
AdminJs.ValidationError(errors)
My usage example:
if(Object.keys(errors).length) {throw new AdminJs.ValidationError(errors)} else {...}
Good luck with your development!

I am creating an application in Svelte Sapper. I have a routes/account/login.js API route where I am trying to use mysql2. The route itself works (I checked with Postman), but as soon as I import mysql, the server crashes and an error appears:
[rollup-plugin-svelte] The following packages did not export their `package.json` file so we could not check the "svelte" field. If you had difficulties importing svelte components from a package, then please contact the author and ask them to export the package.json file.
- mysql2
import mysql from "mysql2/promise";
export async function post(req, res) {
//route test
const { login, password } = req.body;
res.end(`${login}, ${password}`);
}
What can I do to make this import work?
What can I do to make this import work?
The Sapper documentation doesn't say anything about whether you need to change something in the configuration additionally. https://sapper.svelte.dev/docs#Server_routes
I found a solution. I had to create a #lib folder in the src/node_modules folder and there file eg. db.js. In that file instead of import you need to use require()! and then you have to export the function that connects to the database. and then you can import that in the path
//src/node_modules/#lib/db.js
const mysql = require("mysql2");
export async function connectToDatabase() {
return mysql.createConnection({
host: "localhost",
....
})
}
//routes/account/login.js
import { query } from "#lib/db";
export async function post(req, res) {
...
}
I have a react app running redux and thunk which has all been working fine. I need to persist the store state on page reload so that data is not lost, so have created a function which is storing data in the localstorage and then returning the data ready for adding to createStore (https://stackoverflow.com/a/45857898/801861). The data storage is working fine and returning the object ready for setting the sate. When adding the data object at createStore react fails to compile with this error:
Error: It looks like you are passing several store enhancers to createStore(). This is not supported. Instead, compose them together to a single function
Here is CURRENT CODE RETURNING ERROR:
const store = createStore(reducers, LoadState, applyMiddleware(thunk) );
//Error: It looks like you are passing several store enhancers to createStore(). This is not supported. Instead, compose them together to a single function
My original code which was running:
const store = createStore(reducers, applyMiddleware(thunk) );
I attempted to fix this following some similar issues I found online, compiles but breaks site code which was originally working fine:
const composeEnhancers = LoadState || compose;
const store = createStore(reducers, composeEnhancers( applyMiddleware(thunk) ) );
//Error: Actions must be plain objects. Use custom middleware for async actions.
Not sure what I need to change to get this to work, any help is appreciated.
I think you are following a tutorial which is performing tasks in a previous version of redux.
You need to create a composeEnhancer which will take in your Redux Dev Tools extension as shown
const composeEnhancer = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
after importing compose from 'redux' obviously as shown -
import {createStore, compose, applyMiddleware} from 'redux';
and then, you can create the store as shown -
const Store = createStore(rootReducer, composeEnhancer(applyMiddleware(thunk)))
The error is self-explanatory. It tells you what to do exactly!!
Namely it tell you that you should compose your enhancers instead.
Here is how to it:
Step #1: Import 'compose' from redux library
import { createStore, applyMiddleware, compose } from 'redux';
Step #2: Compose your list of enhancers since you have more than one
const enhancers = [LoadState, applyMiddleware(thunk)];
const store = createStore(
reducers,
compose(...enhancers)
);
Refer to this page for more details.
I suspect your issue is within your LoadState. What ever is it? Here is a working createStore:
const store = createStore(
reducers,
{ counter: { count: 5 } },
applyMiddleware(() => dispatch => {
console.log('Yoyoyo')
return dispatch;
}));
Hope it solves your issue. Make sure to put actual initial state values and not some function or what ever it is LoadState is :)
You can use a package to persist the redux store into the local storage and you don't need to make your own function:
https://github.com/rt2zz/redux-persist
In the first example of the package you can see how to use the persistReducer() and persistStore() to save your state and then auto rehydrates on refresh page.
plz check this advanced store setup that may help you
enter link description here
https://github.com/zalmoxisus/redux-devtools-extension#12-advanced-store-setup
import { createStore, applyMiddleware, compose } from 'redux';
+ const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
+ const store = createStore(reducer, /* preloadedState, */ composeEnhancers(
- const store = createStore(reducer, /* preloadedState, */ compose(
applyMiddleware(...middleware)
));
Am starting out with it React-Redux and faced the same issue. am not sure if it is the right approach but here we go.
the one issue you only need to fix in your code is to call the function,
store = createStore(reducers, LoadState(), applyMiddleware(thunk) );
this solution worked for me.
For redux saga users,
import createSagaMiddleware from "redux-saga";
const sagaMiddleware = createSagaMiddleware();
const composeEnhancer = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
const store = createStore(rootReducer, composeEnhancer(applyMiddleware(sagaMiddleware)))
import { applyMiddleware, compose, createStore } from "redux";
import { devToolsEnhancer } from "redux-devtools-extension";
import { logger } from "./middlewares/logger";
import reducers from "./reducers";
import { todoReducer } from "./todoReducer";
const store = createStore(
reducers,
compose(applyMiddleware(logger), devToolsEnhancer({ trace: true }))
);
export default store;
I have a strange problem with my application. I get an error, and I can't solve it. First at all, I installed a new project, so everything is clean. Someone sent me this repo to use for an Angular, Electron and Nodejs Application. Everything worked fine, but then I decided to install an embedded database like sqlite3. For this I found NeDB, and the module is perfect for my needs. First I had the problem, has nothing to do with my general problem, that I can't create a database file. So I read that I can only create files in my application path, because something about Electron and that's working in a browser.
I found the getAppPath() method that is implemented in my app object from the Electron module. Here starts the problem. For hours I tried to get the application path from this object. Finally, I wrote this code.
import { Injectable } from '#angular/core';
var nedb = require('nedb');
import { app } from 'electron';
import * as path from 'path';
#Injectable()
export class DatabaseService {
app: typeof app;
Database: any;
constructor() {
this.app = window.require("electron").app;
this.Database = new nedb({ filename: path.join(this.app.getAppPath(), '/diary.db'), autoload: true, timestampData: true });
var scott = {
name: 'Scott',
twitter: '#ScottWRobinson'
};
this.Database.insert(scott, function(err, doc) {
console.log('Inserted', doc.name, 'with ID', doc._id);
});
}
}
And I get this error.
I found this posting, but I don't really understand what the post is trying to tell me. I followed the links, but nothing seems to help. Anyone have an idea?
i´v got a class which i want to export and import it in another file.
//db.js
class sqlConn {
constru....
}
modules.exports = sqlConn;
I tried to import it, but that doenst worked for me...
//main.html
var sqlConn = require('path_to_file');
var obj = new sqlConn(...);
That gives me following error:
Uncaught Error: Cannot find module 'path_to_file'
can someone help me?
Edit on some answers
I´m using electron with node.js
and my class is laying on an html server.
Also i´m trying to import all in an index.html to sahre an electron.exe which imports all with ajax.
Pass the good path on the required function :
var sqlConn = require('./db'); // or other path if the file db.js isn't on the same folder
but I see main.html, you try to use a node.js code into html?
If you're using ES6/ES2015 you can import the class:
db.js:
class sqlConn {
...
}
export { sqlConn as default }
main.html:
import sqlConn from './path_to_file');
var obj = new sqlConn(...);
Already tried. Gives me error: Uncaught SyntaxError: Unexpected token import
Did you try the require syntaxt?
const db = require('./db');
I have two files, one of them is the app.js and the otherone is api.js.
In the first file I have :
app.use(setHeader)
app.use(api.routes())
app.use(api.allowedMethods())
And in api.js I have:
import KoaRouter from 'koa-router';
const api = new Router();
//Validatekey
const validateKey = async (ctx, next) => {
const { authorization } = ctx.request.headers;
console.log(authorization);
if (authorization !== ctx.state.authorizationHeader) {
return ctx.throw(401);
}
await next();
}
api.get('/pets', validateKey, pets.list);
When I run the project a error message is throw: Router is not defined.
But If I write both files together, the application go fine.
Anybody knows the problem?
I have solved with var Router = require('koa-router')
The import is currently not implemented in nodejs, neither is it supported in the latest ES2015(ES6).
You will need to use a transpiler like Babel to use import in code.I advice that avoid transpiler as it cause performance issues on production just go with require and it will work.
Obviously Nodejs does not support import / export syntax and using require will solve your problem.
However it is possible to make import work on Node.js by using babel transformers.
