apollographql-sequelize

apollographql-sequelize is a nodejs library for dealing with translation from graphql AST to sequlize option used on find query

Installation

npm i apollographql-sequelize

Usage

schema sample (more schema sample on test file)

#has many
query users($where: WhereUser, $order: [OrderUser], $cartsWhere2: WhereCart) {
  users(where: $where, order: $order) {
    firstName
    age
    Carts (where: $cartsWhere2) {
      user_id
      item_type
      item_id
    }
  }
}

{
  "where": {
    "age": {
      "eq": 20
    }
  },
  "order": [
    "AGE_ASC",
    "CARTS__ITEM_ID_DESC"
  ],
  "cartsWhere2": {
    "item_type": {
      "eq": "PRODUCT"
    }
  }
}

then on resolver use this code as a sample

# resolver
const { GetOutput, AssociationToInclude, GetValidAttributes, ParseResolverArgsOrder, ParseResolverArgsWhere } = require('apollographql-sequelize');

sampleQuery(parent, args, context, info) {
    const opt = {};
    if (args.where) {
      opt.where = ParseResolverArgsWhere(args.where);
    }
    if (args.order) {
      opt.order = ParseResolverArgsOrder(model, args.order);
    }
    const output = GetOutput(info);
    opt.attributes = GetValidAttributes(model, output.attributes);
    if (output.associations) {
      opt.include = AssociationToInclude(model, output.associations);
    }
    sequelizeModel.findAll(opt)
}
