History

Sebastian Abondano 195f7d39ee GraphQL support to get transactions by address Why: * We'd like to add support for GraphQL queries to get transactions by address hash. RPC API users could use this instead of the `txlist` RPC API action. Example usage: 1. ``` query($hash: AddressHash!, $first: Int!) { address(hash: $hash) { transactions(first: $first) { edges { node { hash blockNumber } cursor } } } ``` 2. with pagination support via [Relay Cursor Connections](https://facebook.github.io/relay/graphql/connections.htm) ``` query($hash: AddressHash!, $first: Int!, $after: String!) { address(hash: $hash) { transactions(first: $first, after: $after) { pageInfo { hasNextPage hasPreviousPage } edges { node { hash blockNumber } cursor } } } } ``` * Issue link: n/a This change addresses the need by: * Renaming `BlockScoutWeb.Schema.Query.AddressTest` to `...AddressesTest` for the name to match the query field it is testing. * Adding `:absinthe_relay` dependency to `BlockScoutWeb` app for Absinthe support for the [Relay framework](https://facebook.github.io/relay/graphql/connections.htm). * Editing `BlockScoutWeb.Schema` to use `Absinthe.Relay.Schema`, define a node interface, and define a node field. This was necessary to support relay connections. * Adding an `address` field to `BlockScoutWeb.Schema`, to get a single address by hash. * Adding a `TransactionConnection` field to the `address` object type in `BlockScoutWeb.Schema.Types` * Configuring the `transaction` object type as a node, in `BlockScoutWeb.Schema.Types`. * Adding a resolver function in `BlockScoutWeb.Resolvers.Address`, to get a single address. * Adding a resolver function in `BlockScoutWeb.Resolvers.Transaction`, to get transactions for an address. * Creating `Explorer.GraphQL` for GraphQL API specific Ecto queries. The only function in this module now is `address_to_transactions_query/1`. This function is necessary for `Absinthe.Relay.Connection.from_query/4` to load transactions in the new transaction resolver mentioned above. * Editing RPC API docs to include reference to the GraphQL "transactions" field.		6 years ago

BlockScout Web

This is a tool for inspecting and analyzing the POA Network blockchain from a web browser.

Machine Requirements

Erlang/OTP 20.2+
Elixir 1.5+
Postgres 10.0

Required Accounts

Github for code storage

Setup Instructions

Development

To get BlockScout Web interface up and running locally:

Setup ../explorer
Set up some default configuration with: $ cp config/dev.secret.exs.example config/dev.secret.esx
Install Node.js dependencies with $ cd assets && npm install && cd ..
Start Phoenix with $ mix phx.server (This can be run from this directory or the project root: the project root is recommended.)

Now you can visit localhost:4000 from your browser.

You can also run IEx (Interactive Elixir): $ iex -S mix phx.server (This can be run from this directory or the project root: the project root is recommended.)

Testing

Build the assets: cd assets && npm run build
Format the Elixir code: mix format
Run the test suite with coverage: mix coveralls.html
Lint the Elixir code: mix credo --strict
Run the dialyzer: mix dialyzer --halt-exit-status
Check the Elixir code for vulnerabilities: mix sobelow --config
Update translations templates and translations and check there are no uncommitted changes: mix gettext.extract --merge
Lint the JavaScript code: cd assets && npm run eslint

Internationalization

The app is currently internationalized. It is only localized to U.S. English.

To translate new strings, run $ mix gettext.extract --merge and edit the new strings in priv/gettext/en/LC_MESSAGES/default.po.
