Esplora Block Explorer

Block explorer web interface based on the esplora-electrs HTTP API.

Written as a single-page app in a reactive and functional style using rxjs and cycle.js.

Mainnet, Testnet and Elements high performance electrum server

Developing

To start a development server with live babel/browserify transpilation, run:

$ git clone https://github.com/Blockstream/esplora && cd esplora
$ npm install
$ export API_URL=http://localhost:3000/ # or https://blockstream.info/api/ if you don't have a local API server
(see more config options below)
$ npm run dev-server

The server will be available at

To display debugging information for the Rx streams in the web developer console, set localStorage.debug = '*' and refresh.

Client polling

Browser polling uses three shared cadence tiers defined in client/src/const.js:

Fast (30 seconds): chain tip, pending block templates, and recent mempool

transactions shown on the dashboard and recent-transactions page.

Standard (60 seconds): mempool summary, fee estimates, and pending peg

transactions.

Slow (10 minutes): the Bitcoin market chart, the Liquid high-value-assets

panel, and a block-list safety poll used to detect same-height reorganizations.

View-scoped polls run only while their view is active and the browser window is focused. Their first tick occurs after a full interval because route entry already requests the initial data. This avoids sending duplicate requests when opening a page. The chain tip is global and also refreshes immediately when the application starts or a block, transaction, or address page is opened.

The block list refreshes when the chain tip height changes, with the slow safety poll covering same-height reorganizations. Confirmed peg state and peg chain transactions also refresh on new blocks rather than on a timer. A newly observed tip resets pending block template polling and delays the next request by 15 seconds so the electrs cache can refresh.

The dashboard requests both /mempool/recent and /mempool because they serve different UI contracts. /mempool/recent supplies the recent transaction list; /mempool supplies aggregate backlog fields such as transaction count, virtual size, total fees, and the fee histogram used by congestion and transaction fee analysis.

Building

To build the static assets directory for production deployment, set config options (see below) and run $ npm run dist. The files will be created under dist/.

Because Esplora is a single-page app, the HTTP server needs to be configured to serve the index.html file in reply to missing pages. See contrib/nginx.conf.in for example nginx configuration (TL;DR: try_files $uri /index.html).

Pre-rendering server (noscript)

To start a pre-rendering server that generates static HTML replies suitable for noscript users, run:

# (clone, cd, "npm install" and configure as above)

$ export STATIC_ROOT=http://localhost:5000/ # for loading CSS, images and fonts $ npm run prerender-server

The server will be available at

Configuration options

All options are optional.

GUI options

NODE_ENV - set to production to enable js minification, or to development to disable (defaults to production)
BASE_HREF - base href for user interface (defaults to /, change if not served from the root directory)
BASE_PREFIX - optional path prefix prepended to each flavor's BASE_HREF, to serve the whole multi-network site under a sub-directory (e.g. BASE_PREFIX=preview serves /preview/, /preview/signet/, ...). API_URL is left un-prefixed so a prefixed build still uses the same backend
STATIC_ROOT - root for static assets (defaults to BASE_HREF, change to load static assets from a different server)
API_URL - URL for HTTP REST API (defaults to /api, change if the API is available elsewhere)
CANONICAL_URL - absolute base url for user interface (optional, only required for opensearch and canonical link tags)
NATIVE_ASSET_LABEL - the name of the network native asset (defaults to BTC)
TARGET_BLOCK_INTERVAL_SECONDS - expected time between blocks, used for confirmation ETAs (defaults to 60 for Elements chains and 600 otherwise)
SITE_TITLE - website title for </code> (defaults to <code>Block Explorer</code>)</li> <li><code>SITE_DESC</code> - meta description (defaults to <code>Esplora Block Explorer</code>)</li> <li><code>HOME_TITLE</code> - text for homepage title (defaults to <code>SITE_TITLE</code>)</li> <li><code>SITE_FOOTER</code> - text for page footer (defaults to <code>Powered by esplora</code>)</li> <li><code>HEAD_HTML</code> - custom html to inject at the end of <code><head></code></li> <li><code>FOOT_HTML</code> - custom html to inject at the end of <code><body></code></li> <li><code>CUSTOM_ASSETS</code> - space separated list of static assets to add to the build</li> <li><code>CUSTOM_CSS</code> - space separated list of css files to append into <code>style.css</code></li> <li><code>NOSCRIPT_REDIR</code> - redirect noscript users to <code>{request_path}?nojs</code> (should be captured server-side and redirected to the prerender server, also see <code>NOSCRIPT_REDIR_BASE</code> in dev server options)</li> <li><code>NAVBAR_HTML</code> - display navigation bar</li></ul> Note that <code>API_URL</code> should be set to the publicly-reachable URL where the user's browser can issue requests at. (that is, <em>not</em> via <code>localhost</code>, unless you're setting up a dev environment where the browser is running on the same machine as the API server.) <p>Elements-only configuration:</p> <ul><li><code>IS_ELEMENTS</code> - set to <code>1</code> to indicate this is an Elements-based chain (enables asset issuance and Elements-specific features)</li> <li><code>SHOW_HIGH_VALUE_ASSETS</code> - set to <code>1</code> to show circulating values for selected assets on the Liquid mainnet dashboard (enabled by the Liquid mainnet flavor)</li> <li><code>NATIVE_ASSET_ID</code> - the ID of the native asset used to pay fees (defaults to <code>6f0279e9ed041c3d710a9f57d0c02928416460c4b722ae3457a11eec381c526d</code>, the asset id for BTC)</li> <li><code>BLIND_PREFIX</code> - the base58 address prefix byte used for confidential addresses (defaults to <code>12</code>)</li> <li><code>PARENT_CHAIN_EXPLORER_TXOUT</code> - URL format for linking to transaction outputs on the parent chain, with <code>{txid}</code> and <code>{vout}</code> as placeholders. Example: <code>https://blockstream.info/tx/{txid}#output:{vout}</code></li> <li><code>PARENT_CHAIN_EXPLORER_ADDRESS</code> - URL format for linking to addresses on parent chain, with <code>{addr}</code> replaced by the address. Example: <code>https://blockstream.info/address/{addr}</code></li> <li><code>ASSET_MAP_URL</code> - url to load json asset map (in the "minimal" format)</li></ul> Menu configuration (useful for inter-linking multiple instances on different networks): <ul><li><code>MENU_ITEMS</code> - json map of menu items, where the key is the label and the value is the url</li> <li><code>MENU_ACTIVE</code> - the active menu item identified by its label</li></ul> <h3>Development server options</h3> <p>All GUI options, plus:</p> <ul><li><code>PORT</code> - port to bind http development server (defaults to <code>5000</code>)</li> <li><code>CORS_ALLOW</code> - value to set for <code>Access-Control-Allow-Origin</code> header (optional)</li> <li><code>NOSCRIPT_REDIR_BASE</code> - base url for prerender server, for redirecting <code>?nojs</code> requests (should be set alongside <code>NOSCRIPT_REDIR</code>)</li></ul> <h3>Pre-rendering server options</h3> <p>All GUI options, plus:</p> <ul><li><code>PORT</code> - port to bind pre-rendering server (defaults to <code>5001</code>)</li></ul> Note that unlike the regular JavaScript-based app that sends API requests from the client-side, the pre-rendering server sends API requests from the server-side. This means that <code>API_URL</code> should be configured to the URL reachable by the server, typically <code>http://localhost:3000/</code>. <h2>How to build the Docker image</h2> <p>Build the base image first:</p> <pre><code class="bash">docker build -t blockstream/esplora-base -f contrib/Dockerfile.base .</code></pre> <p>then the main image:</p> <pre><code class="bash">docker build -t esplora -f contrib/Dockerfile .</code></pre> <p>Alternatively, you may use the pre-built <a href="https://hub.docker.com/r/blockstream/esplora" target="_blank" rel="noopener"><code>blockstream/esplora</code> image</a> from Docker Hub.
