Task description

In the chart on the homepage, the "Price" always says $2 because it is hardcoded. Fetch the live data from Coinbase API and display the accurate price for each date in the chart.

[Iwueseiter]

Hi @mazurroman can I work on this?
I’m a frontend developer and also a blockchain developer. I’ve work on projects on onlydust before.

I’d go through the code and understand. Then to implement the task, I’d get the latest price from coin base API using endPoint. I’d integrate the fetched data into the cart to display the accurate prices. Then set up regular updates to ensure prices are updated regularly by calling the API at intervals.
I’d deliver a PR promptly if assigned.

UI: Live price for the homepage chart

Hello Walnut team,

I am Joel Vargas, and I'm member of Dojo Coding. I also come from OnlyDust

I would like to request the assignment of the issue related to using the live price in the chart. As a previous contributor to your project, I am familiar with the codebase and would be happy to contribute. Below is my proposed approach for implementing this issue:

How I plan on tackling this issue

Implementation Plan

• Fetch the Price:
  Assuming that the fetchHomePageData function already retrieves the data, the implementation in the chart section can be achieved with the following things.

Initial Data Setup:
Set the initial data to display a placeholder value (e.g., $2) while the real data is being fetched. This is done with the following code:

const initialData = Array.from({ length: 15 }, (_, i) => {
  const date = subDays(new Date(), 15 - i);
  return {
    name: format(date, "MMM d"),
    date: format(date, "yyyy-MM-dd"),
    transactionsCount: Math.floor(Math.random() * 200) + 400,
    price: 2,
  };
});

State Management:
Use useState to manage the chart data:

const [data, setData] =
    useState<
      { name: string; date: string; transactionsCount: number; price: number }[]
    >(initialData);

Data Fetching:
Use useEffect to fetch the data and update the chart:

useEffect(() => {
    const fetchData = async () => {
      const { tokensPrices } = await fetchHomePageData();

      const chartData = Array.from({ length: 15 }, (_, i) => i).map((i) => {
        const date = subDays(new Date(), 15 - i);
        return {
          name: format(date, "MMM d"),
          date: format(date, "yyyy-MM-dd"),
          transactionsCount: Math.floor(Math.random() * 200) + 400,
          price: tokensPrices.op.today,
        };
      });

      setData(chartData);
    };

    fetchData();
  }, []);

• Changes in transaction-history.tsx:
  

With this approach, we get these results:

While the data is loading:

When the data is ready:

I am willing to follow any specific guidelines the team may have. I appreciate the opportunity to contribute and am ready to start as soon as the issue is assigned to me.

My background and how it can be leveraged

Hello
I’m Isaac, a JavaScript developer with notable experience contributing to projects on OnlyDust on and off the ODHACK. I am a returning contributor to your project and would love to contribute more here.

I’m skilled in using JavaScript and typescript to build out efficient solutions and this experience of mine can be seen on my OnlyDust profile at https://app.onlydust.com/u/Dprof-in-tech and on my GitHub at https://github.com/dprof-in-tech

I have my proposed solution to this issue below.

How I plan on tackling this issue

Here's my plan for improving the chart on the homepage by integrating dynamic data from the Coinbase API:

Analyze the Current Chart Code:
    First, I'll go through the existing code for the chart on the homepage.
    I'll locate where the hardcoded $2 price is being set.

Research the Coinbase API:
    I'll check out the Coinbase API documentation to find the right endpoint for historical price data.
    I'll figure out the parameters needed, like the cryptocurrency symbol and date range.

Set Up API Access:
    If necessary, I'll sign up for a Coinbase developer account.
    I'll get any required API keys or authentication credentials.

Create a Function to Fetch Data:
    I'll write an asynchronous function using fetch or axios to make API requests.
    I'll include error handling for network issues or API errors.

Determine the Date Range:
    I'll identify the start and end dates currently shown in the chart.
    I'll format these dates according to Coinbase API requirements.

Fetch Historical Price Data:
    I'll call the API function with the appropriate date range and cryptocurrency.
    I'll parse the JSON response to extract the price data for each date.

Format the Data for the Chart:
    I'll transform the API response into the format expected by the charting library.
    I'll ensure that dates and prices are correctly mapped.

Update the Chart Rendering Function:
    I'll modify the existing chart code to use the new dynamic data instead of hardcoded values.
    I'll update any data processing or formatting logic as needed.


Add Loading Indicators:
    I'll display a loading spinner or message while fetching data.
    I'll ensure a smooth transition when updating the chart with new data.

Implement Error Handling:
    I'll add user-friendly error messages for API failures or data issues.
    I'll provide fallback options, such as displaying the last known good data.

Optimize Performance:
    I'll consider implementing lazy loading or pagination for large date ranges.
    I'll optimize the rendering process to handle frequent updates efficiently.

Update Related Components:
    I'll identify and update any other components that rely on the price data.
    This may include summary statistics, tooltips, or linked visualizations.

Implement Auto-Refresh:
    I'll add a mechanism to periodically refresh the data (e.g., every 5 minutes).
    I'll ensure that refreshes don't disrupt the user experience.

Add User Controls (Optional):
    I'll consider adding options for users to select different date ranges or cryptocurrencies.
    I'll implement any necessary UI elements for these controls.

Thorough Testing:
    I'll test the chart with various date ranges and market conditions.
    I'll verify that the chart correctly handles weekends, holidays, and market closures.
    I'll ensure that the chart remains responsive and accurate during price volatility.

Optimize API Usage:
    I'll implement rate limiting to comply with Coinbase API restrictions.
    I'll consider using websockets for real-time updates if supported.

Document the Changes:
    I'll update any relevant documentation or comments in the code.
    I'll provide clear instructions for maintaining and extending the new functionality.

Conduct a Code Review:
    I'll review the changes with team members to ensure code quality and adherence to best practices.
    I'll address any feedback or suggestions from the review.

Deploy and Monitor:
    I'll deploy the changes to a staging environment for final testing.
    After successful testing, I'll deploy to production.
    I'll monitor the live chart for any issues or unexpected behavior.

@Dprof-in-tech assigning this to you, please don't hesitate to reach out to me if you face any problem regarding this issue.

Regarding your implementation, please follow these guidelines:

• you can see how the Coinbase API is used elsewhere in the homepage, it's not necessary to signup for an API key as this is an unauthenticated API.
• please use standard fetch, do not add axios or another library on top.
• fetch the OP token price, later in the future we will need to add this as a config option but it's out of scope at the moment.
• please stay within the scope of this issue which is very limited, in particular do not add loading indicators, auto refresh or additional controls to display another range as this is not needed at the moment.

Very recently shadcn/ui added a Chart component which is supposed to be a thin wrapper over Recharts which is what is used currently in the code base.
If you can achieve a similar result by switching from plain Recharts to this new shadcn/ui component please do so.
