Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

http.createServer(function(request, response) {

  var uri = url.parse(request.url).pathname
    , filename = path.join(process.cwd(), uri);

/**
 * A function to take a string written in dot notation style, and use it to

 *
 * Useful in a plugin or module that accepts a JSON array of objects, but
 * you want to let the user specify where to find various bits of data
 * inside of each custom object instead of forcing a standardized

Try-catch oneliner

If you search npm with query try await you will find a big modules list (you can find it in the boottom).

What all this developers want is just more clear way to use try catch. All of them suggest to use:

const tryCatch = require('try-catch');
const [error, data] = tryCatch(JSON.parse, 'hello');
