i am trying to make a simple React/Truffle project.
Truffle-config file:
module.exports = {
contracts_build_directory: "./src/contracts",
networks: {
development: {
host: "127.0.0.1",
port: 7545,
network_id: "*",
}
},
mocha: {
},
compilers: {
solc: {
}
}
};
The migrations work and json files get created. However, when i run truffle test
Compiling your contracts...

I've been searching stackoverflow for a while but couldn't find a solution.
You should use build_directory instead of contracts_build_directory

I have a stand alone script that I am using to create an admin user. There will always be only one admin user. However, when I run the standalone script using node command in my nextjs project, I get this weird error below

Node.js v19.3.0
The script I am running has the below code:
import bcrypt from 'bcryptjs';
import MongoClientConnection from '../db';
import readline from 'readline';
import { logger } from '../logger';
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout,
});
rl.question('Enter username: ', (username) => {
rl.question('Enter email: ', (email) => {
rl.question('Enter password: ', async (password) => {
const hashedPassword = await bcrypt.hash(password, 10);
const adminUserData = { username, email, hashedPassword };
try {
const db = await MongoClientConnection.Get();
const res = await db.insert(adminUserData);
} catch (e) {
logger.error(e);
}
rl.close();
});
});
});
In the code above, when I remove import MongoClientConnection from '../db'; the script works fine so, I believe the error is because of mongodb. I am using singleton connection for mongodb and have the below code for that
import { MongoClient } from 'mongodb';
const MongoClientConnection = (() => {
let db = null;
let instance = 0;
const DbConnect = async () => {
try {
let url = process.env.DB_URL;
let mongoClient = await MongoClient.connect(url, {
useUnifiedTopology: true,
});
const mongoDbInstance = mongoClient.db(process.env.DB);
return mongoDbInstance;
} catch (e) {
return e;
}
};
const Get = async () => {
try {
instance++; // this is just to count how many times our singleton is called.
console.log(`DbConnection called ${instance} times`);
if (db != null) {
console.log(`db connection is already alive`);
return db;
} else {
console.log(`getting new db connection`);
db = await DbConnect();
return db;
}
} catch (e) {
return e;
}
};
return {
Get: Get,
};
})();
export default MongoClientConnection;
Cannot really find any solution to this.

Why?Tanks!
In Node.js, I noticed that file operations were not always stable. I have the impression that fs gives up when the operations are not completely finished. Here is an example to illustrate:
"use strict";
Error.stackTraceLimit = Infinity;
const fs = require("fs");
const filename = "foo.txt";
for (let i = 0; ; i++) {
try {
fs.writeFileSync(filename, "bar");
fs.unlinkSync(filename);
}
catch (e) {
throw Object.assign(new Error(`Error at iteration ${i}!`), { cause: e });
}
}
After a certain number of iterations, I get an error :
Error: Error at iteration 12980!

Do you have the same observation?
How can we ensure that these operations are stable?
I am trying to declare a logger object, then have a child function write to the log that was declared in the parent using the context. However the context appears to be undefined inside the children, whether I use an arrow function or not.
Is it possible to pass the winston object to the child function implicitly ie without having to pass a winston object as a parameter?
Error log output:
this main context: {}
undefined

I'm trying to make a model for my dcauser table. I get stuck because it returns an error 'Unrecognized datatype for attribute'. Now i don't know if i messed something up in the database or is sequelize not working correctly with my DB or did i mess something up in the code below. I followed some guides but i get always stuck on the same problem i mentioned above.
var Sequelize = require('sequelize');
var sequelize = new Sequelize('postgres://postgres:xpwdx#localhost:xportx/xdbx');
const UserSchema = sequelize.define(
'dcauser',
{
userid: {
type: Sequelize.Integer,
allowNull: false,
}
}
);
module.exports = UserSchema;
i get the following error:
C:\Users\luka\source\repos\dcaBotManager\node_modules\sequelize\lib\model.js:1005
throw new Error(`Unrecognized datatype for attribute "${this.name}.${name}"`);
^

The integer keyword must be in uppercase
{
userid: {
type: Sequelize.INTEGER,
allowNull: false,
}
}
INTEGER must be in uppercase. See
https://sequelize.org/v5/manual/data-types.html
Though you should start using DataTypes.INTEGER instead.
