Cypress Browser Testing tool that becomes popular recently. Looking forward to exploring it
Firebase : For its easy and quick set up procedure, user with any level of experience get a mini production level project to spin on. Its real time ,web socket feature is another huge bonus!
React Broad community, Write once and use everywhere. The concept is the core. My personal favorite Node.JS framework and most experienced one. Notes for everyone : Enterprise level can go really complicated than you think React is.
Node.js : Developing backend with your favorite Node.js and experience the power of Express.js. Also supporting socket programming which provides the feature for some real time stream service, chat, game,voice,etc.
Stack Overflow : Broad community to help developer find almost any type of question. Voting system is also an inspiration for folks who are new to this community.
Postman Util tool for API test, team collaboration supported. Very handy for testing API and provide a neat UI to configure your own API request.
Vue.js : Very similar to React but with much less legacy to take care of. Because of this even more light weight feature and quick setup step, it is really nice to work with VueJS so far. Notes for everyone : Enterprise level VueJS can grow as complicated as React as well.
Docker Potentially use to create a isolate,virtual server for backend. Personally haven't done anything big but just helped out my team to config and fix bug out of it. Looking forward to spending more time digging on it
GitHub Basically the ticket of your developer journey. Certain conventions are encouraged to follow.
