QuickServe has a built-in Self-Healing Mode that handles certificate generation for you. You just need to tweak your settings.json.

Here is the exact setup.

The Baseline Configuration

Navigate to Settings > Extensions > User/Workspace > QuickServe Configuration (or just open your settings.json).

You'll be targeting this JSON block:

"quickserve.https": {
    "enable": true,
    "certPath": "",
    "keyPath": ""
}

By setting "enable": true and leaving the paths empty, QuickServe takes over. What happens next depends on what is installed on your machine.

Method 1: The Self-Healing Fallback (With Browser Warning)

If you don't have any local Certificate Authority tools installed, do absolutely nothing else.

With the empty paths above, QuickServe's Self-Healing Mode kicks in. It automatically generates a standard self-signed certificate in the background to serve your project over HTTPS.

Result: Your browser will throw an ERR_CERT_AUTHORITY_INVALID warning because it's self-signed. Just click Advanced > Proceed to localhost to bypass it, and you're good for quick testing.

Method 2: Trusted Local CA (No Browser Warning)

Use mkcert to create a local Certificate Authority. This permanently prevents browser warnings and avoids strict cross-origin blocks.

1. Install mkcert:

# macOS
brew install mkcert

# Windows (using Chocolatey)
choco install mkcert

# Linux (Ubuntu/Debian)
sudo apt install libnss3-tools mkcert

2. Setup the local CA (Run once per machine):

mkcert -install

3. Let QuickServe Take Over:

With mkcert installed and the certPath/keyPath still empty in your settings.json, simply restart the QuickServe extension. The Self-Healing Mode will detect mkcert and automatically generate a fully trusted local certificate for you.

Result: A smooth, trusted https://127.0.0.1 connection. No red text, no warnings.

Bonus: The Manual Override

If you already have your own custom OpenSSL certificates and want to bypass the Self-Healing Mode entirely, just provide the absolute paths in your settings.json:

JSON

"quickserve.https": {
    "enable": true,
    "certPath": "/absolute/path/to/cert.pem",
    "keyPath": "/absolute/path/to/key.pem"
}

Save the file, restart the extension, and QuickServe will use your specific files.
