Report

Today I have have an actual app! You can click around and do stuff! Not much but... In all seriousness, today you can create an account an log-in, stay logged, and see a list of characters. There's still a lot of features to develop, but I'm making progress, however slowly. Anyway here's what I did today.

Finished up authentication.

First priority was fixing a bug in the user signup. The form validation failed continuously failed, preventing a user from signing up. I'm using HTML5 form validation on the signup fields, and despite meeting the requirements the password kept being rejected as invalid.

A Tale of Debugging

I started debugging yesterday after I encountered the error. I started my search under the assumption that something was wrong with the password field since that was what threw the error. Given my inexperience with regex I focused my debugging efforts there. Today I decided to remove the pattern attribute on my password field and discovered that the validation failed even without the pattern!

And that is why you shouldn't make assumptions. I should have through checked to verify what was wrong with the form before jumping into debugging regex. After some testing I realized that the validation on all the field failed and that something in that page's javascript was causing the bug. In the end the javascript was cruft and needed to be wiped anyway.

I didn't identify the exact source of the bug, I'm guessing it was the setCustomValidity() function? That doesn't seem likely given what the function is supposed to do according to the documentation. If anyone is interested here's the offending code.

// public/js/users/login.js
$(document).ready(() => {
    document
        .getElementById("signup-password")
        .setCustomValidity(
            "Include 1 lowercase, 1 uppercase, and 1 number.\n Minimum 8 characters, maximum 40 characters."
        );

    $("form").on("submit", e => {
        e.preventDefault();
        const $form = $(e.target);
        fetch($form.prop("action"), {
            method: "POST",
            credentials: "same-origin",
            redirect: "follow",
            headers: {
                "Content-Type": "application/x-www-form-urlencoded"
            },
            body: $form.serialize()
        })
            .then(response => {
                if (response.redirected) {
                    window.location.href = response.url;
                } else {
                    return response.json();
                }
            })
            .then(data => {
                console.log(data);
            })
            .catch(err => {
                console.log(err);
            });
    });
});
// views/users/login.ejs
<form action="/users/signup" method="post">
    <div class="form-group">
        <label for="signup-email">Email</label>
        <input
            type="email"
            name="email"
            id="signup-email"
            class="form-control"
            required
        />
    </div>
    <div class="form-group">
        <label for="signup-username">Username</label>
        <input
            type="text"
            name="username"
            id="signup-username"
            class="form-control"
            required
        />
    </div>
    <div class="form-group">
        <label for="signup-password">Password</label>
        <input
            type="password"
            name="password"
            id="signup-password"
            class="form-control"
            required
            minlength="8"
            maxlength="50"
            pattern="^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.{8,50})"
        />
    </div>
    <div class="form-group">
        <button class="btn" type="submit">Signup</button>
    </div>
</form>

I also add some flash messages from the server to provide error messages with the signup is invalid. Here's the flash middleware.

// index.js
app.use((req, res, next) => {
    req.flash = function (flash) {
        this.session.sessionFlash = { type: flash.type, message: flash.message };
        return this;
    };
    res.locals.sessionFlash = req.session.sessionFlash;
    req.session.sessionFlash = null;
    next();
});

Lastly I began persisting the state(making it so that sessions could last past a server shutdown) to the mongo database.

Wrote a Character List view

I wrote a simple Character List view. It still initial and needs testing but it's accessible in app via a link in the navbar.


Thanks for reading!
