+
+Abstract
+
+   PSA for frustrated Internet searchers
+
+Body
+
+   When pushing Socii[1] to production, I ran into a couple of problems
+   and I'm sharing them on my blog for you (learn from my mistakes!) and
+   me (external memory source). This post will go over how I dealt with
+   secure sessions not working out of the box with HTTPS.
+
+   Let's start with some code. I'm using Feathers with Express but this
+   code will still work sans Feathers:
+
+   ```javascript
+   const app = express(feathers())
+     // above removed for brevity
+
+     // Initialize session and restore auth state
+     .use(session({
+       cookie: {
+         httpOnly: process.env.NODE_ENV !== "development",
+         path: "/",
+         maxAge: 1000 * 60 * 60 * 24 * 7, // 1 week
+         secure: process.env.NODE_ENV !== "development"
+       },
+       proxy: process.env.NODE_ENV !== "development",
+       resave: false,
+       rolling: true,
+       saveUninitialized: true,
+       secret: secret,   // this should be an environment variable
+       store: store,     // your session store of choice
+     }))
+   ;
+   ```
+
+   The `process.env.NODE_ENV !== "development"` is a clever shortcut I
+   found while troubleshooting this issue. If `process.env.NODE_ENV`
+   does not equal `development`, the result will be true in a production
+   environment. In a development environment, the result would be false.
+   This is assuming of course, that your development script sets the
+   environment. Something like this in your `package.json`:
+
+   ```json
+   {
+     …above removed for brevity
+
+     "scripts": {
+       "build": "npm run clean && npm install && npm run build-server",
+       "build-server": "babel -d build server",
+       "clean": "rm -rf build package-lock.json && mkdir build",
+       "deploy": "vagrant push",
+       "dev": "NODE_ENV=development nodemon server/index.js --ignore 'public/' --exec babel-node --presets env,stage-2",
+       "sass": "sass --watch sass:public/css --style compressed",
+       "start": "npm run build && NODE_ENV=production node build/index.js",
+       "test": "echo \"Error: no test specified\" && exit 1"
+     }
+   }
+   ```
+
+   The scripts to pay attention are `dev` and `start`. You can see that
+   I set the node environment before running my app. And there you have
+   it, I hope you've found this post helpful!
+
+   Going back to the `express-session` code above, I list what most of
+   the parameters mean:
+
+   1. proxy
+      Trust the reverse proxy when setting secure cookies (via the
+      "X-Forwarded-Proto" header). The default value is undefined.
+
+      - `true` The "X-Forwarded-Proto" header will be used.
+      - `false` All headers are ignored and the connection is considered
+        secure only if there is a direct TLS/SSL connection.
+      - `undefined` Uses the "trust proxy" setting from express
+
+   2. resave
+
+      Forces the session to be saved back to the session store, even if
+      the session was never modified during the request.
+
+   3. rolling
+
+      Force a session identifier cookie to be set on every response. The
+      expiration is reset to the original maxAge, resetting the
+      expiration countdown.
+
+      The default value is false.
+
+      *Note* When this option is set to `true` but the
+      `saveUninitialized` option is set to `false`, the cookie will not
+      be set on a response with an uninitialized session.
+
+   4. saveUninitialized
+
+      Forces a session that is "uninitialized" to be saved to the store.
+      A session is uninitialized when it is new but not modified.
+
+   5. httpOnly
+
+      Ensures the cookie is sent only over HTTP(S), not client
+      JavaScript, helping to protect against cross-site
+      scripting attacks.
+
+   6. secure
+
+      Ensures the browser only sends the cookie over HTTPS.
+
+   Hope this helps! 🕸
