Up to the point of writing this tutorial I had used es2015-node5 (which I can't remember why it worked better than es2015) but according to the documentation we just need to use the env preset.īabel-preset-env is a new preset, first released over a year ago that replaces many presets that were previously used including: babel-preset-es2015, babel-preset-es2016, babel-preset-es2017, babel-preset-latest other community plugins involving es20xx: babel-preset-node5, babel-preset-es2015-node, etc This is where we'll let babel know what we need it to look out for.
Now create another file, you can do this through the terminal touch. This would create the package.json file which keeps track of the packages required. Getting startedĪs per every node project, the best way to start is by creating a directory and running npm init -y into it from the terminal ( -y automatically answers yes to all the questions that you'd otherwise need to answer or manually skip). This means that those two packages are installed on your computer and will work for any future projects and any set up independent on your local computer. Next, we should install nodemon and babel-node globally. Since this is for node, we would obviously need to have node and npm (or yarn) installed - the installation for those two is beyond the scope of this tutorial. Installing globally locks you down to a specific version of webpack and could fail in projects that use a different version.
This locks you down to a specific version of webpack and might fail in projects that use a different version. However, this is not a recommended practice. The webpack command is now available globally. Global Installation npm install webpack -g. We assume you have node and npm already installed.Webpack 4 - Resolving globally installed dependencies When using NPM (or yarn ) to manage JavaScript dependencies for a project, it is best practice to install the dependencies locally in the project so that multiple NPM projects on the system do not have clashing dependencies or dependency versions. # create project directory mkdir hello-app cd hello-app # install latest version of webpack locally npm init -y # will generate package.json file npm install -save-dev webpack # will generate node_modules directory.
Install webpack We would do a local installation of webpack, so that it’s easier to maintain/upgrade projects individually. Today I am going to explain how I use babel to quickly enable ES6 when working in node, and how webpack can be used when working with react.
