Data science skills are of no value unless you have data to work with. Automating your data retrieval through application program interfaces (APIs) is a process that any data scientist must understand. In this 12-video course, learners will explore how to create RESTful OAuth APIs using Node.js. Begin with API prerequisites, installing the prerequisites to create an API using Node.js, and building a RESTful API using Node.js and Express.js. You will next discover how to build a RESTful API with OAuth in Node.js, before examining what OAuth is and why it is required. Learn about creating an HTTP server using Hapi.js; then look at how to use modules in your API using Node.js, and how to return data with JSON using Node.js. Learners explore using nodemon for development workflow in Node.js and learn how to make HTTP requests with Node.js by using request library. Use POSTman to test your Node.js API and deploy APIs with Node.js. Connect to social media APIs with Node.js to return data. A concluding exercise deals with building RESTful APIs.
