Run an express server on localhost with HTTP2 and SSL for free.
Serve static files or import as module in your project.
Add the root certificate we just generated to your list of trusted certificates. This step depends on the operating system you're running:
-
Mac OS: open Keychain Access, choose System from the left navigation bar, choose "Import items..." from the File app menu and select the file. Then double-click on the certificate and select always-trust in the Trust panel.
-
Linux: Depending on your Linux distribution, you can use
trust,update-ca-certificatesor another command to mark the generated root certificate as trusted.
From terminal navigate into the folder and run sudo npm install -g to install this tool globally.
Then serve static file with sudo serve <static-path>.
Install the dependency with npm install -s https-localhost.
Then just require this module, it will start the server automatically.
For example, put in your index.js file:
const app = require('https-localhost')
app.get('/', (req, res) => res.send('Hello World!'))
You can close the server with app.close().
Closing the server is an async operation, you can get notified with app.close(callback) or app.close().then(...).
