海外TECH	DEV Community	Nhost CLI: from Zero to Production	https://dev.to/nhost/nhost-cli-from-zero-to-production-220h	Nhost CLI from Zero to ProductionIn the previous tutorials that are covered in the documentation we tested various parts of Nhost such as DatabaseGraphQL APIPermissionJavaScript SDKAuthenticationAll changes we did to our database and API happened directly in the production of our Nhost app It s not ideal for making changes in production because you might break things which will affect all users of your app Instead it s recommended to make changes and test your app locally before deploying those changes to production To do changes locally we need to have a complete Nhost app running locally which the Nhost CLI does The Nhost CLI matches your production application in a local environment this way you can make changes and test your code before deploying your changes to production Recommended workflow with NhostDevelop locally using the Nhost CLI Push changes to GitHub Nhost automatically applies changes to production What you ll learn in this guide Use the Nhost CLI to create a local environmentConnect a GitHub repository with a Nhost appDeploy local changes to production Setup the recommended workflow with NhostWhat follows is a detailed tutorial on how you setup Nhost for this workflow Create Nhost AppCreate a new Nhost app for this tutorial It s important that you create a new Nhost app for this guide instead of reusing an old Nhost app because we want to start with a clean Nhost app Create new GitHub RepositoryCreate a new GitHub repository for your new Nhost app The repo can be both private or public Connect GitHub Repository to Nhost AppIn the Nhost Console go to the dashboard of your Nhost app and click Connect to GitHub Install the Nhost CLIInstall the Nhost CLI using the following command sudo curl L https raw githubusercontent com nhost cli main get sh bashInitialize a new Nhost App locally nhost init n nhost example app amp amp cd nhost example appAnd initialize the GitHub repository in the same folder echo nhost example app gt gt README mdgit initgit add README mdgit commit m first commit git branch M maingit remote add origin github username nhost example app gitgit push u origin mainNow go back to the Nhost Console and click Deployments You just made a new deployment to your Nhost app If you click on the deployment you can see that nothing was really deployed That s because we just made a change to the README file Let s do some backend changes Local changesStart Nhost locally nhost devMake sure you have Docker installed on your computer It s required for Nhost to work The nhost dev command will automatically start a complete Nhost environment locally on your computer using PostgresHasuraAuthenticationStorageServerless FunctionsMailhogYou use this local environment to do changes and testing before you deploy your changes to production Running nhost dev also starts the Hasura Console It s important that you use the Hasura Console that is started automatically when you do changes This way changes are automatically tracked for you In the Hasura Console create a new table customers with two columns idnameWhen we created the customers table there was also a migration created automatically The migration was created at under nhost migrations default ls la nhost migrations defaulttotal drwxr xr x eli staff Feb drwxr xr x eli staff Feb drwxr xr x eli staff Feb create table public customersThis database migration has only been applied locally meaning you created the customers table locally but it does not yet exists in production To apply the local change to production we need to commit the changes and push it to GitHub Nhost will then automatically pick up the change in the repository and apply the changes You can commit and push files in another terminal while still having nhost dev running git add Agit commit m Initialized Nhost and added a customers table git pushHead over to the Deployments tab in the Nhost console to see the deployment Once the deployment finishes the customers table is created in production We ve now completed the recommended workflow with Nhost Develop locally using the Nhost CLI Push changes to GitHub Nhost deploys changes to production Apply metadata and Serverless FunctionsIn the previous section we only created a new table customers Using the CLI you can also do changes to other parts of your backend There are three things the CLI and the GitHub integration track and applies to production Database migrationsHasura MetadataServerless FunctionsFor this section let s do one change to the Hasura metadata and create one serverless function Hasura MetadataWe ll add permissions to the users table making sure users can only see their own data For this go to the auth schema and click on the users table then click on Permissions and enter a new role user and create a new select permission for that role Create the permission with custom check id eq X Hasura User Id Select the following columns idcreated atdisplay nameavatar urlemailThen click Save permissions Now let s do a git status again to confirm the permission changes we did were tracked locally in your git repository We can now commit this change git add Agit commit m added permission for uses Now let s create a serverless function before we push all changes to GitHub so Nhost can deploy our changes Serverless FunctionA serverless function is a piece of code written in JavaScript or TypeScript that takes an HTTP request and returns a response Here s an example import Request Response from express export default req Request res Response gt res status send Hello req query name Serverless functions are placed in the functions folder of your repository Every file will become its own endpoint Before we create our serverless function we ll install express which is a requirement for serverless functions to work npm install express or with yarnyarn add expressWe ll use TypeScript so we ll install two type definitions too npm install d types node types express or with yarnyarn add D types node types expressThen we ll create a file functions time tsIn the file time ts we ll add the following code to create our serverless function import Request Response from express export default req Request res Response gt return res status send Hello req query name It s now new Date toUTCString We can now test the function locally Locally the backend URL is http localhost Functions are under v functions And every function s path and filename becomes an API endpoint This means our function functions time ts is at http localhost v functions time Let s use curl to test our new function curl http localhost v functions timeHello undefined It s now Sun Feb GMTAnd with a query parameter with our name curl http localhost v functions time name JohanHello Johan It s now Sun Feb GMTAgain let s use git status to see the changes we did to create our serverless function Now let s commit the changes and push them to GitHub git add Agit commit m added serverless function git pushIn the Nhost Console click on the new deployment to see detailsAfter Nhost has finished deploying your changes we can test them in production First let s confirm that the user permissions are applied Then let s confirm that the serverless function was deployed Again we ll use curl curl name Johan ConclusionIn this tutorial we have installed the Nhost CLI and created a local Nhost environment to do local development and testing In the local environment we ve made changes to our database to Hasura s metadata and created a serverless function We ve connected a GitHub repository and pushed our changes to GitHub We ve seen Nhost automatically deploying our changes and we ve verified that the changes were applied In summary we ve set up a productive environment using the recommended Nhost workflow Develop locally using the Nhost CLI Push changes to GitHub Nhost deploys changes to production In addition to all that the Nhost team is always happy to support you with any questions you might have on Discord and
