All dfuse.io services for EOSIO, running from your laptop or from a container, released as a single statically linked binary:

dfuseeos
.

See the general dfuse repository for other blockchain protocols implementations.

Getting started

If it's the first time you boot a

nodeos
node, please review https://developers.eos.io/welcome/latest/tutorials/bios-boot-sequence and make sure you get a grasp of what this blockchain node is capable.

The default settings of

dfuseeos
allow you to quickly bootstrap a working development chain by also managing the block producing node for you.

Requirements

Operating System

  • Linux or macOS (no Windows support for now, should work through WSL2 (untested))

dfuse Instrumented nodeos (deep-mind)

  • See DEPENDENCIES.md for instructions on how to get an instrumented
    nodeos
    binary.

Installing

From a pre-built release

From source

Build requirements: *

Git
*
Go
1.14 or higher (installation) *
yarn
1.15 or higher (installation)
./scripts/build.sh

This will install the binary in your

$GOPATH/bin
folder (normally
$HOME/go/bin
). Make sure this folder is in your
PATH
env variable. If it's missing, take a look at TROUBLESHOOTING.md.

Note -- If you're getting yarn dependency warnings while running the

yarn install && yarn build
commands above, you can normally safely ignore those and move forward with the installation. If you're getting an error while installing and/or compiling, see TROUBLESHOOTING.md.

Creating a new local chain with
dfuseeos

1. Initialize

Initialize a few configuration files in your working directory (

dfuse.yaml
,
mindreader/config.ini
, ...)
dfuseeos init

Answer

y
(yes) when being prompted for
Do you want dfuse for EOSIO to run a producing node for you?
. If you intend is to sync an existing chain, follow Syncing an existing chain with
dfuseeos
instead.

2. Boot

Optionally, you can also copy over a boot sequence to have dfuse bootstraps your chain with accounts + system contracts to have a chain ready for development in a matter of seconds:

wget -O bootseq.yaml https://raw.githubusercontent.com/dfuse-io/dfuse-eosio/develop/devel/standard/bootseq.yaml

When you're ready, boot your instance with:

dfuseeos start

A successful start will list the launching applications as well as the graphical interfaces with their relevant links:

Dashboard:        http://localhost:8081

Explorer & APIs: http://localhost:8080 GraphiQL: http://localhost:8080/graphiql

In this mode, two nodeos instances will now be running on your machine, a block producer node and a mindreader node, and the dfuse services should be ready in a couple seconds.

Syncing an existing chain with
dfuseeos

If you chose to sync to an existing chain, only the mindreader node will launch. It may take a while for the initial sync depending on the size of the chain and the services may generate various error logs until it catches up (more options for quickly syncing with an existing chain will be proposed in upcoming releases).
