Google API Express Server

Intended as an example for utilizing Google APIs.

Installation

npm install
npm install -g foreman # Install foreman globally

.env File Example

Update your .env file to look similar.

{
    "server": {
        "ip": "0.0.0.0",
        "port": 3000
    },
    "auth": {
        "secret": "YourSecretHere", /* Add your public key here for RS256 */
        "algorithm": "HS256" /* or RS256, etc. */
    },
    "google": {
        "auth": {
            /* Your Google JSON Secret */
        },
        "api": {
            /* Deliminate scopes with a comma */
            "scopes": "https://www.googleapis.com/auth/calendar,https://www.googleapis.com/auth/drive"
        },
        "calendar": {
            "id": ""
        }
    }
}

Generate Keys

We'll use a either a secret key or RSA public key for verifying using JSON Web Tokens for certain API requests. Generate a private and public key using the below commands for RS256.

# RS256 key
openssl genrsa -out keys/priv.pem 1024
openssl rsa -pubout -in keys/priv.pem -out keys/pub.pem

Get Access Token

Generate an access token and use it for authenticated API requests.

# RS256
const privateKey = fs.readFileSync('keys/priv.pem');
const RS_256_ACCESS_TOKEN = jwt.sign({}, privateKey, { algorithm: 'RS256'})

# HS256
const HS256_ACCESS_TOKEN = jwt.sign({}, AUTH_SECRET);

The token should be in the Authorization Header.

// Authorization: Bearer <token>
req.headers['authorization'];

Starting API Server
