How this library was built

In order to create and upload this library to Npm, we have used C-J Kihl's tutorial from Medium.

Important things to keep in mind;

• Start the project
• Configure it.
• Create a build (transpile it with tsc).
• format it and paint it with Prettier and Tlint.
• Test it with Jest in the best case.

Once the library is finished, we create a commit and upload it to github using git push in order to continue with the steps to upload it to npm.

Let's publish the lib to npm with:

npm publish

And that's all 🎉. It's interstingt to know we can make diferent versions with:

npm version patch

Thanks for reading!
