Preface 97 As indicated in the above table, to get a listing with all the ‘stories’ we have to make an HTTP GET or HEAD request to api/stories. To update an existing story we have to make an HTTP PUT or PATCH request to api/stories/{storyID} providing the data we want to override, and replacing {storyID} with the id of the story we want to update. The same logic applies to all endpoints, I think you get the idea. Assuming your server is running on http://localhost:3000, you can view a listing of all stories in JSON format by visiting http://localhost:3000/api/stories on your web browser. Tip JSON response Reading raw JSON data on browser can be a pain . It is always easier to read a well formatted JSON. Chrome has some great extensions that could format raw JSON data into tree view format that can be easily read. I use JSONFormatter³ because it supports syntax highlighting and displays JSON in tree view where the nodes on the tree can be collapsed or expanded by clicking the triangle icon on the left of each node. It also provides a button for switching to original (raw) data. You can choose whichever extension you like but you should definitely use one! ³https://chrome.google.com/webstore/detail/json-formatter/bcjindcccaagfpapjjmafapmmgkkhgoa
9. Working with real data It is time to actually put to use our database and perform the operations we have mentioned (CRUD). We will utilize the last example from the Components chapter, but this time of course our data will be coming from an external source. To exchange data with the server we need to perform asynchronous HTTP (Ajax) requests. Info AJAX is a technique that allows web pages to be updated asynchronously by exchanging small amounts of data with the server behind the scenes. 9.1 Get Data Asynchronous Take a moment to have a look at the last example from the Components chapter. As you can see we hardcode stories array inside the data object of Vue instance. Stories array hardcoded 1 new Vue({ 2 data: { 3 stories: [ 4 { 5 plot: 'My horse is amazing.', 6 writer: 'Mr. Weebl', 7 }, 8 { 9 plot: 'Narwhals invented Shish Kebab.', 10 writer: 'Mr. Weebl', 11 }, 12 ... 13 ] 14 } 15 }) This time, we want to fetch the existing stories from the server. 98
