![[SOLVED] Web322 assignment 2 create and publish a web app that uses multiple routes which serve static content (text / json)](https://assignmentchef.com/wp-content/uploads/2022/08/downloadzip.jpg)
Create and publish a web app that uses multiple routes which serve static content (text / json) as well as create a “data service” module for accessing data.
As with the previous assignment, we will first be creating the files and directories for our solution. To begin:
Now we now have the data for the assignment.
The purpose of the “data-service.js” file is to provide easy access to the Site data for other files within our assignment that require it.
To start, add the following two lines to the beginning of the “data-service.js” file:
const siteData = require(“../data/NHSiteData”);
const provinceAndTerritoryData = require(“../data/provinceAndTerritoryData”);
This will automatically read both files and generate two arrays of objects: “siteData” and “provinceAndTerritoryData”.
Next, create a variable called “sites”, initialized to an empty array, ie:
let sites = [];
This will be the completed array of Site objects, after processing the above “siteData” and “provinceAndTerritoryData” arrays.
The remainder of this file will contain functions, according to the following specification:
{
“siteId”: “BC010”,
“site”: “Butchart Gardens”,
“description”: “Internationally known gardens, including remarkable Sunken Garden in a former limestone quarry; unique combination of 3 aspects of Canadian gardening history: early 20th-century estate garden, early twentieth century beautification movement, and the Victorian bedding out system”,
“date”: 1904,
“dateType”: “established”,
“image”: “https://upload.wikimedia.org/wikipedia/commons/thumb/d/d9/Sunken_Garden.jpg/360px-Sunken_Garden.jpg”,
“location”: “Brentwood Bay”,
“latitude”: “48.56528”,
“longitude”: “-123.46944”,
“designated”: 2004,
“provinceOrTerritoryCode”: “BC”
}
However, each of these objects must also include a new “provinceOrTerritoryObj” property. The value of the “provinceOrTerritoryObj” property should be the corresponding provinceOrTerritory object from the provinceAndTerritoryData.json file, whose “code” value matches the “provinceOrTerritoryCode” for the “siteData” object.
For example, in the above “siteData” object, we have a “provinceOrTerritoryCode” value of “BC”. Therefore, we must add an additional “provinceOrTerritoryObj” property with the value of { “code”: “BC”, “name”: “British Columbia”, “type”: “province”, “region”: “West Coast”, “capital”: “Victoria” }
since the “code” value for the object is also “BC” within the provinceAndTerritoryData.json file.
This will result in the following object being added (pushed) to the “sites” array:
{
“siteId”: “BC010”,
“site”: “Butchart Gardens”,
“description”: “Internationally known gardens, including remarkable Sunken Garden in a former limestone quarry; unique combination of 3 aspects of Canadian gardening history: early 20th-century estate garden, early twentieth century beautification movement, and the Victorian bedding out system”,
“date”: 1904,
“dateType”: “established”,
“image”: “https://upload.wikimedia.org/wikipedia/commons/thumb/d/d9/Sunken_Garden.jpg/360px-Sunken_Garden.jpg”,
“location”: “Brentwood Bay”,
“latitude”: “48.56528”,
“longitude”: “-123.46944”,
“designated”: 2004,
“provinceOrTerritoryCode”: “BC”,
“provinceOrTerritoryObj”: {
“code”: “BC”,
“name”: “British Columbia”,
“type”: “province”,
“region”: “West Coast”,
“capital”: “Victoria”
}
}
As an additional example, consider the following object from a “siteData” array:
{
“siteId”: “QC001”,
“site”: “Acton Vale Railway Station (Grand Trunk)”,
“description”: “A small passenger terminal with dormer, turret and bellcast roof; symbolic of the expansion of the Grand Trunk Railway”,
“date”: 1900,
“dateType”: “completed”,
“image”: “https://upload.wikimedia.org/wikipedia/commons/thumb/a/a5/Gare_d%27Acton_Vale_2.JPG/320px-Gare_d%27Acton_Vale_2.JPG”,
“location”: “Acton Vale”,
“latitude”: “45.6482917”,
“longitude”: “-72.5640139”,
“designated”: 1976,
“provinceOrTerritoryCode”: “QC”
}
This has a “provinceOrTerritoryCode” of “QC”. From the “provinceAndTerritoryData.json” file, the object of the province or territory with code “QC” is { “code”: “QC”, “name”: “Quebec”, “type”: “province”, “region”: “Central Canada”, “capital”: “Quebec City” }. Therefore, the new object to be added to the “sites” array should be:
{
“siteId”: “QC001”,
“site”: “Acton Vale Railway Station (Grand Trunk)”,
“description”: “A small passenger terminal with dormer, turret and bellcast roof; symbolic of the expansion of the Grand Trunk Railway”,
“date”: 1900,
“dateType”: “completed”,
“image”: “https://upload.wikimedia.org/wikipedia/commons/thumb/a/a5/Gare_d%27Acton_Vale_2.JPG/320px-Gare_d%27Acton_Vale_2.JPG”,
“location”: “Acton Vale”,
“latitude”: “45.6482917”,
“longitude”: “-72.5640139”,
“designated”: 1976,
“provinceOrTerritoryCode”: “QC”,
“provinceOrTerritoryObj”: {
“code”: “QC”,
“name”: “Quebec”,
“type”: “province”,
“region”: “Central Canada”,
“capital”: “Quebec City”
}
}
HINT: Consider using the .find() and .forEach() Array methods for your solution
This function simply returns the complete “sites” array
This function will return a specific “site” object from the “sites” array, whose “siteId” value matches the value of the “id” parameter, ie: if getSiteById(“ON016”) was invoked, the following site object would be returned:
{
“siteId”: “ON016”,
“site”: “Public Grounds of the Parliament Buildings”,
“description”: “The focal point for national celebrations in Ottawa; the grounds were originally designed by Calvert Vaux, and since supplemented by 18 monuments and memorials”,
“date”: 1875,
“dateType”: “initial completion”,
“image”: “https://upload.wikimedia.org/wikipedia/commons/thumb/5/5f/East_Block_and_Langevin_Block.jpg/320px-East_Block_and_Langevin_Block.jpg”,
“location”: “Ottawa”,
“latitude”: “45.424807”,
“longitude”: “-75.699234”,
“designated”: 1976,
“provinceOrTerritoryCode”: “ON”,
“provinceOrTerritoryObj”: {
“code”: “ON”,
“name”: “Ontario”,
“type”: “province”,
“region”: “Central Canada”,
“capital”: “Toronto”
}
}
HINT: Consider using the .find() Array method for your solution
The purpose of this function is to return an array of objects from the “sites” array whose “name” value of the embedded “provinceOrTerritoryObj” object matches the “name” parameter. However, it is important to note that the “name” parameter may contain only part of the “name” value of the embedded “provinceOrTerritoryObj” object and must be case insensitive. For example:
getSitesByProvinceOrTerritoryName(“Ontario”);
would return all the sites from your “sites” array whose “name” value of the embedded “provinceOrTerritoryObj” object contains the string “Ontario” (ignoring case). For example, if your “sites” array contained the following objects, they would be returned (28 site objects):
[
{
“siteId”: “ON001”,
“site”: “Adelaide Hunter Hoodless Homestead”,
“description”: “The childhood home of activist and organizer Adelaide Hunter Hoodless, educational reformer and co-founder of the Women’s Institute, the National Council of Women of Canada and the Victorian Order of Nurses”,
“date”: 1839,
“dateType”: “completed”,

{
“siteId”: “ON003”,

“provinceOrTerritoryCode”: “ON”,
“provinceOrTerritoryObj”: {
“code”: “ON”,
“name”: “Ontario”,
“type”: “province”,
“region”: “Central Canada”,
“capital”: “Toronto”
}
},
… …

HINT: Consider using the .filter() Array method as well as the .toUpperCase() / .toLowerCase() and .includes() String methods for your solution
The purpose of this function is to return an array of objects from the “sites” array whose “region” value matches the “region” parameter. However, it is important to note that the “region” parameter may contain only part of the “region” string, and case is ignored. For example:
getSitesByProvinceOrTerritoryName(“Prairie Provinces”);
or
getSitesByProvinceOrTerritoryName(“prairie provinces”);
would return all the sites from your “sites” array whose “region” property contains the string “Prairie Provinces” or “prairie provinces” (ignoring case), i.e., all Prairie Provinces’ sites from “sites” array would be returned.
Once you have completed the above four functions, test them at the bottom of your file by first invoking the “initialize()” function, then the others (since they all need the “sites” array to be filled with data).
NOTE: You should be able to run this file using the command “node modules/data-service.js”
If the correct data is returned and you’re satisfied that everything is working correctly, you can delete your testing code.
Now, we can begin to refactor our functions to use “Promises“.
Finally, we must make sure this file functions as a “module“, either by manually adding all 5 functions to the “module.exports” object individually, or by assigning them at once using an object literal shorthand, ie:
module.exports = { initialize, getAllSites, getSiteById, getSitesByProvinceOrTerritoryName, getSitesByRegion }
The final part of this assignment is to create a “simple web server” that makes our data available. For now, this will simply involve returning the data – we will focus on “rendering” actual HTML pages in future assignments.
To begin:
From this point on, we can begin creating a simple web server using Express.js that features simple GET routes.
However, before the server starts (ie: the app.listen() function is invoked), we must ensure that the “sites” array has been successfully built within our “data-service” module. Therefore, we must invoke the siteData.initialize() function and make sure it has completed successfully (ie “resolves”) before we execute our app.listen() function.
NOTE: Even though we do not have any routes configured, we should be able to start the server using the command “node server.js”
Finally, ensure that the following routes are configured in your server.js file:
With your routes complete, you should be ready to hand in our assignment. To see a completed version of this app running, visit: https://as2-322-sample.vercel.app/
