I have a problem importing/writing a function which calculates Currency A into Currency B. The problem is that the function is not recognized properly. My Function:
async function convertRMB(inputAmount) {
const fetch = require("node-fetch");
try {
const responseRMB = await fetch('http://www.floatrates.com/daily/cny.json');
const dataRMB = responseRMB.json();
const rateEUR = dataRMB.eur.rate
const rateUSD = dataRMB.usd.rate
const RMBinEUR = Number(inputAmount) * Number(rateEUR)
const RMBinUSD = Number(inputAmount) * Number(rateUSD)
return RMBinEUR;
} catch (err) { console.log(err) }
}
module.exports = {convertRMB};
The Class im using the function in:
const Discord = require('discord.js');
const convertRMB = require('../functions/convertRMB');
module.exports.run = async (bot, message, args) => {
var inputAmount = args.join(' ');
const amountEUR = convertRMB(inputAmount);
const embed = new Discord.MessageEmbed()
.setDescription(`${inputAmount}RMB = ${amountEUR}€`)
.setFooter("© CSGO Library")
message.channel.send(embed);
convertRMB(inputAmount);
};
module.exports.help = {
name: `rmb`
}
The Error im getting: "TypeError: convertRMB is not a function"
As the error says, "convertRMB" is not a function: it is the export object of your file convertRMB.js. You exported the function convertRMB() as a function of module.export, or to be clearer, is the same thing as:
module.export.convertRMB = function (input) {...};
To obtain what you want, that is to export the function as an anonymous one, you should do something like this:
module.exports = function (input) {...};
Or, using your code, you can use the export object that you have:
module.exports.run = async (bot, message, args) => {
var inputAmount = args.join(' ');
const amountEUR = convertRMB.convertRMB(inputAmount);
const embed = new Discord.MessageEmbed()
.setDescription(`${inputAmount}RMB = ${amountEUR}€`)
.setFooter("© CSGO Library")
message.channel.send(embed);
convertRMB.convertRMB(inputAmount);
};
Here you can find some useful example to better understand the module.export dynamics.
