How can I import custom files in libary.js?

dogs

Hey!

I want to read out a file inside my plugin:

const fs = require("fs");
const config = JSON.parse(fs.readFileSync("./utils/config.json", "utf-8"));

My Folder-Structure looks like this:

ubuntu@ubuntu:~/nodebb-linked-modules/nodebb-plugin-sync-bot$ ls
lib  library.js  node_modules  package.json  plugin.json  static  utils

Inside of utils is the file config.json which I have to read via the fs.

const config = JSON.parse(fs.readFileSync("./utils/config.json", "utf-8"));

On startup I receive the following error:

error: Error: ENOENT: no such file or directory, open './utils/config.json'

How can I import files in the same directory to work with it?

I checked the file permissions. They are identical.

Looking forwar to your answers.

@pitaj Many thanks for your effort

Okay so I just npm link'ed my plugin again so I thought some file will be updated. But they weren't.

Here is my full source code of libary.js:

'use strict';


/* NodeBB Basic Plugin Libraries */
const controllers = require('./lib/controllers');
const plugin = {};


/* Third Party Libraries */
const Discord = require("discord.js");
const fs = require("fs");

// Nodebb Discord Bot 
const config = JSON.parse(fs.readFileSync("./utils/config.json", "utf-8"));
var client = new Discord.Client();



let debug = true;

plugin.init = function (params, callback, client) {
	
	myDebug("nodebb-discord-bot-started");

	callback();
};


function myDebug(msg){
	if(debug){
		console.log(msg);
	}
}

module.exports = plugin;

I tried it with path again:

// Nodebb Discord Bot 
var configpath = path.join(__dirname, 'utils', 'config.json');
const config = JSON.parse(fs.readFileSync(configpath, "utf-8"));
var client = new Discord.Client();

an suddenly ... it worked! o.O

I think it was really because I ran npm link again. Funny.* I'm sorry. Most of the time, the problem is in front of the computer.

But still a strange behavior in my opinion. Well ... Good to know for the future. @PitaJ as mentioned thank you for you effort.

For any others having the same issue:

Read the Stackoverflow Solution posted by @PitaJ right here
If it still not work use npm link in ./nodebb again to refresh something in the plugin folder ...I dont know tbh ...

@pitaj My folder with the config.json is in the same directory as library.js is. I tried it with path but it didn't work either.

my-plugin
├── library.js
└── utlis
    └── config.json

var configpath = path.join(__dirname, 'utils', 'config.json');

Results also in:

error: Error: ENOENT: no such file or directory, open './utils/config.json'

What can I do to get it work? Any other suggestions or tips? Would be awesome!

PitaJ

@dogs what you have should work. Are you sure you're using configpath inside the readfilesync?

dogs

@pitaj Oh okay...

Yes I am sure it is the correct path. I als tried different folders like static which is being initialized for scripts and templates. Didn't work either.

Maybe I should open an issue on that topic...

PitaJ

@dogs no please don't open an issue for this. This is certainly not a problem with NodeBB. In fact this is a basic Node.js programming issue

Please share the full source of library.js

The reason I know there's something wrong with your code is that the error mentions ./utils/config.json, but if the correct path with __dirname was passed in, it would be something like node_modules/nodebb-plugin-blah/utils/config.json
