Changes

• Generate AssemblyScript types from the GraphQL schema.
• Validate subgraph manifest and GraphQL schema as part of graph codegen, graph build and graph deploy.
• Make the subgraph.yaml argument optional.
• Print GraphiQL and GraphQL endpoints after deploying a subgraph with graph deploy.
• Add --debug and --verbose CLI flags.
• Improve error output when subgraphs fail to load.
• Show error when trying to run an unknown CLI command (e.g. graph foobarbaz).
• Make console output more compact.
• Make --watch mode more robust by catching subgraph manifest errors.
• Add support for ABI compile output generated by newer versions of Truffle.
• Streamline type conversions between Ethereum values, GraphQL/entity values and AssemblyScript.
• Add test to build the example subgraph in Travis.
• Test compiling all type conversions (Ethereum value <-> AssemblyScript, Entity attributes <-> AssemblyScript) in the example subgraph.
• Set exit code to 1 if graph build or graph deploy fails.
• Bump graph-ts dependency to v0.4.0.

Code generation for GraphQL schema

graph codegen now generates a schema.ts file in the output directory, with Entity subclasses for all entity types in the subgraph's GraphQL schema. You can then use these via

import { ParcelCreated . from /.types/Parcels/ParcelRegistry.ts`
import { Parcel } from './types/schema'

function handleParcelCreated(parcel: ParcelCreated) {
  let parcel = new Parcel()
  parcel.name = parcel.params.name
  parcel.owner = parcel.params.owner
  store.set('Parcel', parcel.params.parcelId.toHex(), parcel)
}
