EosApi

Run nodeos

Usage

EosApi = require('eosjs-api') // Or EosApi = require('./src')
 
eos = EosApi() // // 127.0.0.1:8888
 
// Any API call without a callback parameter will print documentation: description,
// parameters, return value, and possible errors.  All methods and documentation
// are created from JSON files in eosjs/json/api/v1..
eos.getInfo()
 
// A Promise is returned if a callback is not provided.
eos.getInfo({}).then(result => console.log(result))
eos.getBlock(1).then(result => console.log(result))
 
// For callbacks instead of Promises provide a callback
callback = (err, res) => {err ? console.error(err) : console.log(res)}
 
// The server does not expect any parameters only the callback is needed
eos.getInfo(callback)
 
// Parameters are added before the callback
eos.getBlock(1, callback)
 
// Parameters can be an object
eos.getBlock({block_num_or_id: 1}, callback)
eos.getBlock({block_num_or_id: 1}).then(result => console.log(result))

Configuration

EosApi = require('eosjs-api') // Or EosApi = require('./src')
 
// everything is optional
options = {
  httpEndpoint: 'http://127.0.0.1:8888', // default, null for cold-storage
  verbose: false, // API logging
  logger: { // Default logging functions
    log: config.verbose ? console.log : null,
    error: config.verbose ? console.error : null
  },
  fetchConfiguration: {}
}
 
eos = EosApi(options)

options.logger example

During testing, an error may be expected and checked as follows:

options.logger = {
  error: err => {
    assert.equal(err, 'expected error')
    done()
  }
}

options.fetchConfiguration example

options.fetchConfiguration = {
  credentials: 'same-origin'
}

Every eosjs-api request will run fetch with this configuration:

fetch('https://example.com', {
  credentials: 'same-origin'
})
