This command outputs detailed usage instructions for the Fly CLI. The psql command-line application is the go-to tool for anyone working with PostgreSQL. We should be able to run the fly command in our terminal if the Fly CLI has been correctly included in our PATH. Lets use the LB4 CLI lb4 app to create a LoopBack 4 application called MyApp : 2. Now we need to restart our terminal or open a new terminal tab. Instead of the export statements, we need to add something along the lines of: set -x PATH $PATH /path/to/the/.fly/bin Typically we should be able to add the export statements to the bottom of our shell’s rc file: This will allow us to run the fly CLI program in our terminal. Once the CLI has been installed, there’s a message telling us that we need to add the directory path where the CLI has been installed to our shell PATH. We can follow the Installing flyctl documentation to install the Fly CLI. We’ll use the Fly CLI for creating, configuring and deploying our application to Fly. You can check the latest LTS version of Node.js on the Node.js Downloads page. That’s it - the Node.js version specified in engines.node will be automatically detected by Fly. For demonstration purposes, we will use the suppliers sample database. Deleting data from PostgreSQL tables in Python show you how to delete data in a table in Python. The Node.js application I was deploying is built with the Fastify framework, but the steps in this guide should generally apply to any Node.js application you want to deploy to Fly. Handling PostgreSQL BLOB data in Python give you an example of inserting and selecting the PostgreSQL BLOB data in a Python application. This isn’t an exhaustive Fly deployment guide, but it should give you a solid base for getting things up and running. I wrote them up as I figured they might be helpful for other folks looking to deploy Node.js applications on Fly. I recently deployed a Node.js application and Postgres database to Fly while creating my upcoming egghead course.ĭeploying to Fly was mostly a smooth process thanks to their Build, Deploy & Run a Node Application guide, but I discovered a few extra things I needed to take care of along the way. One newer platform offering this style of deployment is Fly.io. Cloud application platforms can help provide a low friction deployment process that’s more "here’s my app, please get it in production for me!". Many Node.js projects don’t require the complexity of "infrastructure as code" based tooling, such as CloudFormation or Terraform.
