WORLD BANK LOAN RECORDS FINDER

Angular.js with $http

##APP

You will be provided with working server code that delivers an API of World Bank Loan data in JSON format. Your mission is to build an Angular front-end that makes use of the data.

######The app should display:

• A clickable list of all values associated with the key region in the database records. It's a list of all the region names with duplicates excluded.
• A dynamic list of all the records associated with a region when the region name is clicked
• The number of records in the database
• A search bar / filter box to narrow down the list of regions
• A working form to add a new record to the database

Image below-- TOP: the number of records is displayed. RIGHT: All region names in the database, duplicates excluded. Search bar / filter box. LEFT: All the records for a given region once the region name is clicked.

Image below-- RIGHT: A form to submit a new record.

STARTER CODE

SEED

You have a seed route within a seed controller. You can seed your database with all the World Bank records by going to /seed in your browser once.

WBINFO

You have a controller for serving Wbinfo data. You don't need to change these or anything else in the server. The routes are:

• /wbinfo/count Serves up a count of all records in the database.

• /wbinfo/uniqueRegions Serves up all values for the key region excluding duplicates.

• /wbinfo/byName/:name Will deliver all records where the region name is the same as req.params.name

• There is also an index route /wbinfo for testing to see if all the data is there.

• And POST /wbinfo for creating a new record.

Use the information served by these routes in your Angular by using $http to get the information.

There is no front-end code given to you, you are building the entirety of the static component of the app in the public folder. Your front-end doesn't have to look anything like the examples given above, just as long as the information from the routes is used and the program flow works.

NOTES

SUGGESTED STEPS

1. Get the number of records and display it on the page
2. Get the region names showing
3. Get click functionality on the region names working
   • Display records associated with a region
4. Get the search box working for fun
5. Add in the form for a new record and make sure data is flowing
   • Get the form to add a new record and display it on the page

MODEL REFERENCE

######A wbinfo record has five strings

• region
• projectabstract

NOTES ON FORM DATA IF YOU GET STUCK (don't look if you don't want spoilers)

You can have an empty object in your controller like formdata = {} that can accept data from an ng-model, and process that object in a function bound to ng-submit.

<form ng-submit="ctrl.processForm()">
	<input type="text" placeholder="region name" ng-model="ctrl.formdata.region"></br>
	<input type="text" placeholder="project name" ng-model="ctrl.formdata.projectname"></br>
	<textarea type="text" placeholder="project abstract" ng-model="ctrl.formdata.projectabstract"></textarea></br>
	<input type="text" placeholder="year approved" ng-model="ctrl.formdata.year"></br>
	<input type="text" placeholder="loan amount" ng-model="ctrl.formdata.loanamnt"></br>
	<button type="submit">SUBMIT</button>
</form>
