Articles, notes and random thoughts on Software Development and Technology
If you’ve staged more files than you intended with a ‘git add .’, if you haven’t committed yet you can selectively unstage files with:
git rm --cached path/filename
If you want to unstage multiple files in a folder, use the recursive flag
git rm --cached -r foldername/
This seems to be a recurring issue after every major OS update. You need to reinstall XCode and the Command Line Tools to get them working again.
Trying a ‘git status’ after upgrading to Ventura over the weekend, I get this error:
> git status xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
To fix this you need to reinstall the XCode Command Line Tools (described here) with:
xcode-select --install
Press Install when prompted:
After the install completes, restart your Terminal and you should be good to go.
I work primarily with AWS and so my first choice for deployment of personal React projects is either a public S3 bucket with Static Website Hosting option enabled, or CloudFront with an S3 origin.
While costs for a site with low traffic will typically cost you < $1 a month with these options, there’s other options available that can be used for personal projects for free. Many of these are covered in this LogRocket article. If you’re already using GitHub, using GitHub Pages to host a React app is pretty easy with the gh-pages utility.
Assuming you have an exising React project, add gh-pages to your app:
npm i --save-dev gh-pages
Edit your package.json and add a couple of scripts:
"predeploy": "npm run build",
"deploy": "gh-pages -d build",
When you run ‘npm run deploy’ predeploy will run first to build your prod app, and then upload it to the remote origin for your git project. Note – this util assumes your GitHub remote repo is called origin, and it will fail with this error if it is called something else:
Failed to get remote.origin.url (task must either be run in a git repository with a configured origin remote or must be configured with the "repo" option).
If you name your remote GitHub repo something else, just add it again with the name origin ‘git remote add origin remote-repo-url’
When gh-pages runs, it uploads the built React app from ./build to a new branch on your repo called gh-pages. If you check the settings for your project, you should see the GitHub Pages settings for your app is configured to use this branch as it’s source:
If it’s using another branch change it to use gh-pages. Hit the url shown in the settings above to load your app from GitHub Pages!
Using gh-pages npm module to build and deploy a React app to github pages I get this error:
Failed to get remote.origin.url (task must either be run in a git repository with a configured origin remote or must be configured with the "repo" option).
According to this answer to an issue logged on the project, gh-pages expects your remote repo to be named ‘origin’ and doesn’t work if you use any other name when you ‘get remote add’ you repo for a project. Add the same repo with the name ‘origin’ and then it works as expected.
