One line deploy¶
After you’ve built your Hoodie app you probably want to put it online. You can choose to deploy your app as read-only or deploy the backend couchdb database as well. This video and the text below descibes how to deploy your app using one line of code. Alternatively, you can deploy your app using Docker, please refer to the Docker section.
Deploying to Now¶
Now allows you to deploy a Node application with its command line tool. It’s 100% free for Open Source projects. You can deploy an app from your computer or right from a GitHub repository. For example, to deploy our Hoodie Tracker demo app all you have to do is to run this command:
$ now hoodiehq/hoodie-app-tracker --npm -e NODE_ENV=production -e hoodie_inMemory=true
To decribe this further:
hoodiehq/hoodie-app-trackeris the GitHub repository slug.
--npmtells now to deploy using npm as there is also Dockerfile in the repository.
-e NODE_ENV=productionsets the NODE_ENV environment variable to production, which makes the deployment faster as no devDependencies will be installed.
-e hoodie_inMemory=truemakes the Hoodie app run in-memory mode, meaning that no data is persisted and no files are written. This is important because now is a read-only file system. That means that all user accounts and data will be lost on the next deployment, but it is great for for a quick test or demo of your application.
Alternatively, add this script to your package.json and you are good to go:
"now-start": "hoodie --inMemory",
Store Data With Cloudant¶
Cloudant is a DBaaS (database-as-a-service). It provides most of CouchDB’s APIs and can be used as Hoodie’s database backend. Signing up for a free account only takes a moment. After sign up, you need to slightly adjust the now deployment command above.
$ now hoodiehq/hoodie-app-tracker -e NODE_ENV=production -e hoodie_inMemory=true -e hoodie_dbUrl=https://username:firstname.lastname@example.org/
hoodie_inMemory environment variable makes sure that Hoodie does not try to write any files like the bundled /hoodie/client.js library. The
hoodie_dbUrl environment variable sets the address and credentials to your CouchDB. Replace username and password to whatever you signed up with.
Test and set an alias¶
When you deploy with now you will receive a random subdomain where you can access your application. It looks something like https://hoodie-app-tracker-randomxyz.now.sh/ and was already copied to your clipboard during the deployment. Open the URL in your browser to give it a try. Once everything is good, you can change the subdomain to your preference by running:
$ now alias set hoodie-app-tracker-randomxyz my-tracker-app
