- exact user reputation
- follower count
- following count
Delegations

- Load account history incrementally
Features Added In This Update
Price History Feed
On the current delegations page, one can see an overview of the delegations a user has made. The delegations view looks like this:
The annual percentage return (APR) is given in the penultimate column.
The calculation for the APR was not correct because it has been assumed that Steem and SBD have more or less the same value. The assumption was made because the app did not retrieve the current prices for Steem and SBD. Therefore a price feed for cryptos has been added in this update.
The prices for the cryptocurrencies are provided by CryptoCompare. The attribution is given in the About page of the application and the README.
Crypto price support has been added to the Redux store. The relevant code can be found in src/state/crypto/.
The part of the state tree looks like this:
priceHistory: {
STEEM: {
inBTC: [1.00],
inUSD: [1.00]
},
SBD: {
inBTC: [1.00],
inUSD: [1.00]
}
},
// EMPTY, LOADED, LOADING
priceHistoryStatus: 'EMPTY'
The operation to request a price history for a cryptocurrency looks like this:
const priceHistoryRequested = (symbol = 'STEEM') => async (dispatch, getState) => { … }
This operation is used in src/App.js to retrieve the prices for Steem and SBD on application startup. When the Redux store holds the prices they will be used on the delegations page and the Dashboard page.
To make the prices easily accesible two selectors have been added:
const steemPrice = cryptoSelectors.selectSteemPrice(state)
const sbdPrice = cryptoSelectors.selectSBDPrice(state)
Improved Calculation Of APR For Current Delegations
With the added support for crypto prices, the calculation of the APR for a delegation has been improved.
The amount of SBD received as a reward for a delegation is now converted to Steem. This amount will be added to the Steem we received for the same delegation on the same day. This sum is the total amount received which then can be used to calculate the APR.
The code can be found in /src/pages/delegation/CurrentDelegations.js.
