Note: This repo contains v1 of the TzStats explorer and is no longer maintained. It may or may not work with the most recent TzIndex API.

Tezos Block Explorer

A block explorer for public and private Tezos blockchain networks based on the TzIndex backend available here. Supported by Blockwatch Data, Pro version available on request.

Develop

# setup dev environment
npm install

# start built-in dev server
yarn start

# build deployable app
yarn build

Running a local block explorer

You can run a local copy of TzStats and link it to your local instance of TzIndex in a few different ways. Easiest is using the Docker images built by the Makefile. If you don't have Docker installed follow the steps below.

Note: TzStats is a single-page Javascript app and the way web browsers work is that you need a local webserver to serve all files to your browser. You can setup a local Nginx or use another light-weight webserver to deliver the pre-built app or you just run the development version using yarn start.

Running the Dev Version

This is probably easier because it uses the built-in server that comes with yarn. Checkout the TzStats repo, create a new top-level file development.env with a single line TZSTATS_API_URL=http://localhost:8000, then run npm install and yarn start. You need NodeJS for this to work.

Running from Pre-Built App

Build TzStats with npm install and yarn build or copy all files from /var/www/ out of the TzStats Docker image. Then compile a local version of https://github.com/echa/serve and run serve with the following env variables: TZSTATS_API_URL (defaults to http://localhost:8000), SV_SERVER_PORT=8001 (smth other than the default port 8000 because TzIndex already uses it), SV_SERVER_ROOT=./build (the directory you built/extracted the compiled TzStats files to). Key trick is that the minified TzStats JS file contains a placeholder <[TZSTATS_API_URL]> which needs to be replaced with your local API endpoint. The embedded webserver Serve does that for you. Then navigate your browser to http://localhost:8001

Deploy (work in progress)

The contained Makefile requires a docker registry endpoint to be set.

DOCKER_REGISTRY_ADDR=<addr> make deploy

will run the following steps

  1. build React web app using yarn build
  2. build Docker image based on the serve file server
  3. publish image to private Docker registry
  4. use docker-compose to start/replace Docker container on remote host

for the deploy process to work the following ENV variables need to be specified:

DOCKER_HOST
DOCKER_REGISTRY_USER
DOCKER_REGISTRY_PASSPHRASE
BLOCKWATCH_API_KEY
DEPLOY_KEYS_PASSWORD

CI/CD pipelines usually store these in a supposedly secure way, but you'll never know, so be vigilant.
