All of this project's code can be found in the First Look monorepo on my GitHub.
Introduction
Fly is a platform for full stack applications and databases that need to run globally. Fly executes your code close to users and scales compute in cities where your app is busiest. You can run arbitrary Docker containers and host popular databases like Postgres.
Fly Setup
Install flyctl
You can download the CLI on Mac, Linux, or Windows.
brew install superfly/tap/flyctl
Create Fly Account
If you are a new user you can create an account with flyctl auth signup.
flyctl auth signup
After your browser opens you can either:
- Sign-up with your name, email and password.
- Sign-up with GitHub and check your email for link to set a password for verification.
You will also be prompted for credit card payment information, required for charges outside the free plan on Fly. See Pricing for more details.
Login to Fly Account
If you already have an account you can login with flyctl auth login.
flyctl auth login
After your browser opens, sign in with your username and password. If you signed up with Github, use the Sign-in with Github button to sign in.
Create Project
mkdir ajcwebdev-fly
cd ajcwebdev-fly
npm init -y
npm i express --save
echo > index.js
echo > Dockerfile
echo > .dockerignore
echo 'node_modules\n.DS_Store' > .gitignore
Create Server
// index.js
const express = require("express")
const app = express()
const port = process.env.PORT || 3000
app.get("/",
(req, res) => {
greeting = "<h1>ajcwebdev-fly</h1>"
res.send(greeting)
}
)
app.listen(port,
() => console.log(`Hello from port ${port}!`)
)
Run Server
node index.js
Hello from port 3000!
Create Dockerfile
Add the following code to Dockerfile in the root directory of your project.
FROM node:14-alpine
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm i
COPY . ./
EXPOSE 8080
CMD [ "node", "index.js" ]
Add the following code to .dockerignore in the same directory as your Dockerfile.
node_modules
Dockerfile
.dockerignore
.git
.gitignore
npm-debug.log
Launch Application on Fly
Run flyctl launch in the directory with your source code to configure your app for deployment. This will create and configure a fly app by inspecting your source code and prompting you to deploy.
flyctl launch --name ajcwebdev-fly
