@wharfkit/transact-plugin-resource-provider

A transactPlugin for use with the @wharfkit/session library that provides resources to perform transactions.

Caveats

• Resource Provider API endpoint must conform to the Resource Provider API specification.
• To allow fees from the Resource Provider, the allowFees parameter must be specified and set to true.
• Any fees must be paid in the networks system token, deployed on the eosio.token account using the standard token contract.

Installation

The @wharfkit/transact-plugin-resource-provider package is distributed as a module on npm.

yarn add @wharfkit/transact-plugin-resource-provider
# or
npm install --save @wharfkit/transact-plugin-resource-provider

Usage

Include when configuring the Session Kit:

import {TransactPluginResourceProvider} from '@wharfkit/transact-plugin-resource-provider'

const kit = new SessionKit(
    {
        // ... your session kit args
    },
    {
        // ... your other options
        transactPlugins: [new TransactPluginResourceProvider()],
    }
)

Or when you are manually configuring a Session:

import {TransactPluginResourceProvider} from '@wharfkit/transact-plugin-resource-provider'

const session = new Session(
    {
        // ... your session kit args
    },
    {
        // ... your other options
        transactPlugins: [new TransactPluginResourceProvider()],
    }
)

The plugin is also capable of utilizing any API that conforms to the Resource Provider API specification. To change the default endpoints, specify them in the constructor as a key/value pair using the chainId and URL.

import {TransactPluginResourceProvider} from '@wharfkit/transact-plugin-resource-provider'

const session = new Session(
    {
        // ... your session kit args
    },
    {
        // ... your other session kit options
        transactPlugins: [
            new TransactPluginResourceProvider({
                endpoints: {
                    '73e4385a2708e6d7048834fbc1079f2fabb17b3c125b146af438971e90716c4d':
                        'https://jungle4.greymass.com',
                },
            }),
        ],
    }
)

The full list of options that can be passed in during instantiation are defined in the ResourceProviderOptions:

interface ResourceProviderOptions {
    // Defaults to true, determines whether or not the user will be prompted with fees.
    allowFees?: boolean
    // The API endpoints to request resources from.
    endpoints?: Record<string, string>
    // The maximum allowed fee, if a fee exists. Provides a sanity check against the API.
    maxFee?: AssetType
}
