Week 2: Async JS & Server Introduction

Learning Outcomes

Achievements

1. Access values that aren’t available synchronously

---

    const { bridge } = require('../../../app');

    /* export the data attribute, then... */

    async execute(interaction) {
        await interaction.deferReply();
        const question = interaction.options.getString('question');
        const reply = await bridge(question);
        await interaction.editReply(reply);
    }

2. Filter & Map

---

discord.js's Collection() method is essentially a Map() with additional utilities

    const { Collection } = require('discord.js');

    client.commands = new Collection();

---

Running a filter() on ./discord/commands/ to return only .js files

    const comPath = path.join(__dirname, 'commands');
    const comSubs = fs.readdirSync(comPath); 
    
    for (const sub of comSubs) {
        const subPath = path
            .join(comPath, sub);
        const subFiles = fs
            .readdirSync(subPath)
            .filter(file => file.endsWith('.js'));
        /* more stuff */
    }

---

3. Managing project dependencies with `npm`

---

    "dependencies": {
        "discord.js": "^14.16.2",
        "dotenv": "^16.4.5",
        "openai": "^4.61.1"
    }

---

4. Protecting keys & secrets

---

I like to store my .env values in an object. It helps with coherent naming and means I can fold it all out of sight

    const dotenv = require('dotenv').config();
    const keys = {
        discord: {
            /* other discord keys */
            token: process.env.DISCORD_TOKEN,
        },
        /* other APIs */
    };
    
    /* other stuff */

    client.login(keys.discord.token);

---

5. Bug Hunting

---

This was horrendous a useful learning experience

---

Difficulties

• Making sure code isn't replicated in multiple files

Feedback

Name: Alexander What Went Well: I love that you used not only code snippets, but also screenshots and even config files to explain your progress. Very well detailed and concise Even Better If: I just would like to see a bit of project management progress. But apart from that there is not much to improve, to be honest.
