Creating Web Services in JavaScrpt

Still working on the slide. That's the general slides. I will take each subtopic and prepare a slide for each.

1. Ready. Steady. Go! The speed of Web Service Creation With JavaScript Oliver Mensah

3. Once Upon a Time? How Applications were: Built Thought of
4. Then there was an evolution Web Services Application Programming Interface  A single point of contact for each of client facing applications. Strategies  REST  GraphQL
5. Creating a REST API Using Nodejs  Bootstrapping Project with Dependencies  Designing the RESTful API Endpoints  Data Modeling and Storage(Mocked Data)  Data Validation  Authorization of endpoint  Cross Origin  Interaction between API and Client
6. Bootstrapping project with dependencies  Add what you need
7. Designing RESTful Endpoints Build around main Entities(resource) Model these Entities Operations occur on the model
8. Data Modeling and Storage/Mocked Data Model Data based on  Inherent structure of the data itself   Application usage of data(queries, updates and data processing
9. Data Validation Where should data be validated  Logic Layer(Controller)  - required  Model Layer(Data Storage)  - optional
10. Cross Origin Request Restrictions:  Get Requests on same origin  CORS request from different domains and ports  - API failure 
11. Demo Interaction between API and Client
12. RESTful APIs Pain Points  More or less data Writing lots of endpoints • Less endpoints with query parameters •
13. Can we do better with Our APIs?
14. Using Nodejs  Bootstrapping Project with Dependencies  Designing the GraphQL Data Model  Developing queries and mutations with Data Storage(Mocked Data)  Authorization to Access Queries and Fields  Interaction between API and Client Creating GraphQL API
15. Questions?
