Reading about Pokémon is one thing, knowing about the 700+ different ones are another. How about an easy to understand chart to break down what types of Pokémon that exists? Or your own Pokedex? Even better what about an amazing simulated battle to watch two Pokémon fight each other.
Welcome to PokéDash, the dashboard that gives you the overview with a dash of fun in! So come and start your own journey!
This was a simple dashboard, but I as a developer found it boring to just have a «Dashboard» they all look the same. Since this was for a well-known game and stats around this, the people should feel right at home. It should feel like they are in the World of Pokémon’s.
The whole thing starts with the loading screen with an animated intro from Pokémon Gold. Just as in the game you would have a «Start Button»
Navigating a Dashboard can always be tricky so be sure to see «Professor Oak» and he will gladly explain what Pokémon’s are and a bit about the page. This was meant for a rough intro to it for users. Once closed the user will not see this again unless the Poké Dex icon in the menu is clicked.
The Pokemon list acts as the Poké Dex, where you can find a small image of each pokemon and some stats about them, this was intended to be looking and styled as a Pokedex, but due to the layout and how the page looks, I felt that this should be more of a table. Though on Mobile a Table can be hard to read, so this was redone to fetch data as small cards for easier understanding and reading on mobile devices.
What is Pokémon without a Pokémon Battle! For me, this was a must and for the project a bonus. Some people really wanted this to be the main event with more functionality and this is something I have planned to do at a later stage. It will change colour depending on if it’s in a fight, waiting, or not started.
The winner is drawn by random by rolling a dice between 0-10.
Again for mobile «cards» were used for simplicity and the way it’s easier for a user to consume.
Page Not Found
I always love good 404 pages, they are supposed to be fun but still have a meaning for the user. This will ruin the surprise with a screenshot so please do visit our the live demo here
If you do not have adobe XD installed you can have a look at the wireframes live on this page. There is also attached a PDF file for those that want to look at it that way.
Pokémon by type
- You can visualise the data and clearly see the amount of Pokémon’s by their type. This means its easy to see how many «Steel», «Electric», «Fairy» types of pokemon there is.
Pokémon Avg Stats
- This is will display the average stats for the all Pokémon’s combined.
- This is a simple table displaying data about each pokemon along with the picture of it.
- A minigame for the visitor to take part in to have fun and play a small round of Pokémon!
Features Left to Implement
- The minigame (aka Battle) needs a bit more attention to details, some people have requested to make use of stats to make a winner instead of random.
- Legend for BarChart, this is working fine for Pie Chart but due to the package, it seems to have an issue with loading undefined on Bar charts.
- Filter by other types. Currently it the table only sorts.
- If the server does not respond and we get an error, you will be stuck on a loading screen, I’m working on implementing an error handler to remove the loading screen and show an error. The reason was I sadly did not get enough time to implement this, but the idea is then to redirect to a page. As without the data we are unable to display anything to the user. - This is now implemented
These are technologies and third-party packages that are used throughout the project
- Angular I’m using this to build all the front end logic and components for my app. As Typescript makes it easy to compile and also easy to scaffold code. > Angular (commonly referred to as «Angular 2+») is a TypeScript-based open-source front-end web application platform led by the Angular Team at Google and by a community of individuals and corporations. Angular is a complete rewrite from the same team that built AngularJS.
Bootswatch - Cosmo Bootswatch is a collection of bootstrap themes. We are using the Cosmo theme modified with some material colours.
Angular CLI The Angular CLI is part of the Angular platform and is a great command-line interface to scaffold, generate, test and lint your code. This makes it easy to scaffold out components that we use in the project, saving time and give more time to focus on developing the application rather than create all the files, import them etc.
Angular2 Charts Angular2 directives for Chart.js. This is used to render our Chart.js within Angular as a native directive. >Angular2 directives for Chart.js
Ngx-pagination A simple solution to create pagination without a lot of code using directives in Angular. On the mobile display we are switching from a table to cards, by using this we can then also add pagination to the same data without calling the directive on the charts. >The simplest solution for pagination in Angular.
NgxSpinner Animated loading spinner service, this is the small clock you will see when making API calls and waiting for data. This then gives a simple service which you can call with
.hide()>An animated loading spinner for Angular 4⁄5 that is intended to inform the user that an operation is in progress.
ngx-toastr An amazing npm module to create minimal toast notification services. Using this to display errors and information on the first screen when fetching the API. >Easy Toasts for Angular
GitHub pages for angular-cli users This is a small dev dependency to make it easier to deploy our project to Github Pages. >Publish to any gh-pages branch on GitHub (or any other branch on any other remote). Made for angular-cli users.
Flask The API backend is written with the Flask Microframwork this is used to loop over the database, create an array and append the results into it for Angular to consume. >Flask is a microframework for Python based on Werkzeug, Jinja 2 and good intentions.
MongoDB The Pokémon data we gathered was a simple CSV file with the help of mongoimport we can make a simple one-line command to import a CSV file into our NoSQL Database. >MongoDB is a free and open-source cross-platform document-oriented database program
Heroku When hosting different applications that are not static Heroku is a great choice at least I think. If the backend is Django, Flask, Node, Ruby On Rails or any other this is a great hosting environment which simplifies a lot of work, it’s also FREE. We can simply push our app to Heroku using their CLI and from there it does everything for you, you can also setup pipelines and pull from a GitHub repo. >Heroku is a cloud platform as a service supporting several programming languages.
See more about this in Deployment below.
mLab In convention with Heroku, this is offered as a free add-on, this means we do not need to spin our anything like a docker image or anything to run our host. >mLab is a fully managed cloud database service that hosts MongoDB databases.
The course teaches and goes into the dept of TDD and writing automatic testing. I’m a person that loves the challenge of searching then test and write code. So I admit that writing a lot of TDD has not been the biggest but I wanted to give it a go.
I wrote a quick and simple test to see if we can get a response with
content_type="application/json" and a response code of
This test should simply check that the route is correct and that it will give you the correct data back.
You can run the unit test by executing the following:
Note: If you are in the folder
api you can simply run
I’m fairly certain that I have done a lot of tests. So for manual tests, we have tested the following
Microsoft Explorer 11 Microsoft Edge (v18) Chrome (v70) Firefox Developer Edition (v62)
I had some issues regarding the battle, where the help text would not update. This was simply because I forgot to rename the help text in
battles.component.ts this was fixed at a later date but now updates correctly.
The user would start a battle and the help text would be
Get Ready to fight. The user then would start the fight and the text would change to
Fight in progress, once the fight was completed it would say
Please stop the Fight to continue.
Now the bug would the be that if a user clicked stop it would still display this message. This was fixed in the following commit #d922680
Since the project is built with Bootstrap 4 (Bootswatch) I’m fairly certain things are responsive, though there will always be widths and heights that are uncommon and will «glitch».
- An example of this was pointed out to me on the following widths and heights
710-726px x 837px 919-935px x 837px
The bug here would be regarding ChartJS and the Angular 2 Charts, where it would try to resize itself and go into an infinite loop. I’m currently working finding a solution but trying to delay the resize or change the breakpoint will then cause it to break on a different breakpoint.
- Go to the Pokémon Stats page
- Resize to any of the above sizes.
710-726px X 837pxor
919-935px X 837px
- You will see that the Chart will try to auto update and flickers.
There is also a bug where if Bar Chart Legend is enabled it will display
undefined, I think the reason for this is that it writes and creates the Legends BEFORE it fetches the data. Sadly I have been unable to fix this, so if you have a way to do this please let me know so this can be fixed.
To reproduce the bug or test this:
2. Change line 38
public barChartLegend = false; to
public barChartLegend = true;
ng serve to start the server
4. Open PokéDash Stats Page or navigate to
You will now see that at the top of the Bar Chart the legend it’s undefined`
Installing and building
NodeJS 8+ (Built with: 10.7.0) NPM 5.6+ (Built with: 6.1.0) Python 3+ (Built with: 3.6.5) Angular 4+ (Built with: 6.1.3)
- Clone the project (The documentation consider the
PokeDashthe root folder)
console git clone https://github.com/Eventyret/PokeDash.git
- Change Directory into the root folder
console cd PokeDash
Create a Virtual Environment (This creates a folder named
.venvto hold python environment files)
Install Python dependencies (This installs all flask dependencies)
pip install -r api\requirements.txt
Install Angular dependencies by running (This installs all the angular dependencies)
Running project locally.
As a developer, I feel its important to give you different ways to run your backend in a simple and clean way, so I have made two ways to run your backend project.
Sidenote: The project has set up a default database to connect to on developer mode, check Deployment for info on how to create a database etc to connect to.
1. Docker (Recommended)
If you have Docker installed you can simply run the command below (This will start the server on port
- Activate the Virtual Environment:
- Start the server
console python api/app.py
Since we are using angular for our build it’s as simple as running:
ng serve in the root folder of the project.
This will start our development server on port
Building the application
Since Angular is built with a mix of HTML, SCSS and Typescript the browser has no clue on how to interpret the languages, so we need to compile this into a web application.
To build your app and make it ready for deployment Angular again gives you a simple command to build and make this ready
ng build --prod --base-href "https://yourdomain.com/
If you are building this to be uploaded directly to the root folder of a domain you can also shorten this by doing
ng build --prod
There is no compiling / building for the backend, so you can just continue to read about deploying the backend.
There is a simple but great git command we can use to upload JUST the backend instead of the whole project folder.
We can use the power of git and use
git subtree to upload and deploy ONLY the API to Heroku you can use the following command.
git subtree push --prefix api heroku master
note the API here which is the folder name we want to push
As we are using mlab to host our database please follow this guide mLab MongoDB | Heroku Dev Center - This will help you set up a database to connect to.
Heroku Environment variables We need to set a secret variable so Heroku knows what database to use.
heroku config:set Development=False
This tells the server that we are in a production environment and chooses the correct database accordingly.
heroku config: set SECRET_URI="mongodb://dbuser:dbpassword@hostname:port/databasename"
All this information you can find on mlab Dashboard once you are logged in. You are looking for an URL like the one in this picture.
Make sure you change the following in that string:
dbuser your mlab username for the database
dbpassword your mlab password for the database
NOTE: Make sure you set the configurations before you push to Heroku, else you won’t get any data back.
After you have built your application you got a few options.
1. If you are uploading to your own domain, just upload the content of the
dist folder and you’re ready to go.
2. If you want to deploy to GitHub Pages there is an amazing dev dependency installed in the project for you named GitHub pages for angular-cli users. So all you need to do is issue the command
npx ngh and the npm package will automatically publish this to your GitHub pages.
Sidenote: If your using this method make sure you do the following command. This is to make it compatible with GitHub pages.
ng build --prod --base-href="https://USERNAME.github.io/REPOSITORY_NAME/"
