Deploy Node js API on AWS\r\nDeploy Node js API on AWS EC2 Instance\r\n\r\nGreat for testing simple deployments on Cloud, VPS\r\n\r\n## Step 1: Install NodeJS and NPM using nvm\r\nInstall node version manager (nvm) by typing the following at the command line.\r\n\r\n```bash\r\nsudo su -\r\ncurl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash\r\n```\r\nActivate nvm by typing the following at the command line.\r\n\r\n```bash\r\n. ~/.nvm/nvm.sh\r\n```\r\n\r\nUse nvm to install the latest version of Node.js by typing the following at the command line.\r\n\r\n```bash\r\nnvm install node\r\n```\r\n\r\nTest that node and npm are installed and running correctly by typing the following at the terminal:\r\n\r\n```bash\r\nnode -v\r\nnpm -v\r\n```\r\n\r\n## Step 2: Install Git and clone repository from GitHub\r\nTo install git, run below commands in the terminal window:\r\n\r\n```bash\r\nsudo apt-get update -y\r\nsudo apt-get install git -y\r\n```\r\nor \r\n```bash\r\nsudo yum update -y\r\nsudo yum install git -y\r\n```\r\n\r\nJust to verify if system has git installed or not, please run below command in terminal:\r\n```bash\r\ngit --version\r\n```\r\n\r\nThis command will print the git version in the terminal.\r\n\r\nRun below command to clone the code repository from Github:\r\n\r\n```bash\r\ngit clone https://github.com/dmhaui/ocr-eop.git\r\n```\r\n\r\nGet inside the directory and Install Packages\r\n\r\n```bash\r\ncd ocr-eop\r\nnpm install\r\n```\r\n\r\nStart the application\r\nTo start the application, run the below command in the terminal:\r\n\r\n```bash\r\nnpm start\r\n```\r\n\r\n# Keep the api alive\r\nNow, we will need to run the api 24/24 even when the EC2 console is closed\r\n\r\nWhen you close the console tab in web view, even though the instance is still running, the code will not function properly\r\n\r\n## Step 1: Install PM2\r\nPM2 will help us continue running our code even after the terminal is closed\r\n\r\nInstall PM2 by typing the following at the command line.\r\n\r\n```bash\r\nnpm install pm2 -g \u0026\u0026 pm2 update\r\n```\r\n\r\n## Step 2: Run the code by PM2\r\n\r\n\r\n### Here are some basic commands for PM2:\r\n\r\npm2 start app.js: Start a Node.js application.\r\n\r\npm2 stop app: Stop a running application.\r\n\r\npm2 restart app: Restart an application.\r\n\r\npm2 list: List all running processes.\r\n\r\npm2 monit: Display a monitoring interface for all running processes.\r\n\r\npm2 logs: View logs of running processes.\r\n\r\npm2 delete app: Remove a process from PM2.\r\n\r\n\r\n### In this project, we will use PM2 to start the server.js file:\r\n\r\n```bash\r\npm2 start server.js\r\n```\r\n\r\n### Retrieve all processes managed:\r\n\r\n```bash\r\npm2 list\r\n```\r\n\r\nWe will see our server.js file displayed in a table.\r\n\r\n### To stop, we can use either the name or the ID from the previous table:\r\n\r\n```bash\r\npm2 stop 0\r\n```\r\n\r\n\r\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flinux-vps%2Focr-eop","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flinux-vps%2Focr-eop","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flinux-vps%2Focr-eop/lists"}
