@semiotic-labs/graph-tables v1.0.0

Highlights

• Simple layout parse function
• Exact same identifier (table, column, enum, etc..) naming from graph-node implementation of postgres schema generation.
• JS mappings used for fast table and column search
• Enum definitions
• Detailed column types including enum and foreign key references
• One to one and one to many table relations
• block$ or block_range column based on the GraphQL entity mutability.
• Package include CommonJS, ES Modules, UMD version and TypeScript declaration files.

Install

npm install graph-tables

Usage

import {parse} from 'graph-tables';

const simple_schema = `
    type SomeComplexTableErc20Name  @entity {
        "Some description about a string field"
        id: ID!,
        nullableField:Boolean,
        booleanField:Boolean!,
        bigIntField:BigInt!,
        bytesField:Bytes!,
        bigDecimalField:BigDecimal!,
        intField:Int!,
        int8Field:Int8!,
        stringField:String!
    }
`;

const layout = parse(simple_schema);
