Cancel a Bid

Prerequisites ⚙️

Install and configure ReservoirKit.

CancelBidModal

ReservoirKit provides a simple to configure modal for canceling a valid bid in your react app. Below is an example of a simple CancelBidModal setup.

import { CancelBidModal } from '@reservoir0x/reservoir-kit-ui'

<CancelBidModal
  trigger={
    <button>
      Cancel Bid
    </button>
  }
  bidId="0x26546d77a4511a2c0c2ab24970cdad886fad35f9f875bbb524f1d92775115153"
  onCancelComplete={(data: any) => {
    console.log('Bid Canceled', data)
  }}
  onCancelError={(error: any, data: any) => {
    console.log('Bid Cancel Error', error, data)
  }}
  onClose={(data, currentStep) => {
    console.log('CancelBidModal Closed')
  }}
/>

Let's dive into the parameters. You'll need to provide an element to trigger the modal, this can be any valid html element. Next you'll want to provide a bidId, it can be set to undefined until the data is ready.

There are also some additional optional props:

Finally you can set some optional callbacks:

onCancelComplete: Triggered when cancelling was completed successfully, returns some useful data about the bid and the cancel step.

onCancelError: Triggered when the cancel resulted in an error, returns the error and the bid data.

onClose: Triggered when the modal was closed. Returns some useful data about the bid as well as the step data and the current step.

Conditional Rendering

ReservoirKit's CancelBidModal doesn't take care of conditionally showing the button/modal based on if the item is cancelable by the user, we leave that logic up to the developer. Below are the requirements for canceling a bid and how to go about getting that data:

• The user needs to have a connected wallet. You can check this by looking for a signer from the useSigner wagmi hook.
• The user must be the maker of the bid, you can check this by comparing maker in the bid object to the connected wallet address. You can get a full list of a wallet's bids by using the useBids hook or the underlying api.

Custom CancelBidModal

The CancelBidModal also comes with a custom renderer which can be used to just get the data layer that the CancelBidModal uses internally to handle the underlying business logic. With the renderer you can rebuild the UI completely to your liking. Below is an example of how it works in practice.

import { CancelBidModal, CancelBidStep } from '@reservoir0x/reservoir-kit-ui'

<CancelBidModal.Custom
    open={open}
    bidId="0x26546d77a4511a2c0c2ab24970cdad886fad35f9f875bbb524f1d92775115153"
  >
    {({
      loading,
      bid,
      tokenId,
      cancelStep,
      transactionError,
      stepData,
      totalUsd,
      blockExplorerBaseUrl,
      cancelOrder,
    }) => {
  { Your Custom React Elements }
})}
</CancelBidModal.Custom>

The custom CancelBidModal takes a few parameters like before with one additional one being the open parameter. This is because there is no trigger, you have control over what sort of modal you want this to eventually live in and how to trigger that modal. You'll have the ability to add a custom button with a custom handler, etc. The custom CancelBidModal then passes some key data into the children which we parse above and use in our custom UI. It's also important to note the CancelBidStep here which is used to manage the internal state of the CancelBidModal's logic. You can decide to use all or some of the data passed into your custom implementation.

👍

Nice job!

Now that we've added a cancel bid modal to your dApp, let's customize the theme to match your brand.
