RCSB Saguaro Web API is an open-source library that includes different tools to validate and request data from the 1D Coordinate Server, the RCSB Data API and the RCSB Search Service.

import {GraphQLRequest} from "@rcsb/rcsb-api-tools/build/RcsbGraphQL/GraphQLRequest"

const client = new GraphQLRequest("data-api"|"1d-coordinates"|url);

client.request(query_params, query_string);

const query_params = {
  queryId: "P01112",
  from: "UNIPROT",
  to: "PDB_ENTITY"
}

         }

 }

E.g. import {CoreEntry, RcsbEntryContainerIdentifiers} from "@rcsb/rcsb-api-tools/build/RcsbGraphQL/Types/Yosemite/GqlTypes";

E.g. import {AnnotationFeatures, Feature, AlignmentResponse} from "@rcsb/rcsb-api-tools/build/RcsbGraphQL/Types/Borrego/GqlTypes";

        logical_operator: LogicalOperator.And,
    },
    return_type: ReturnType.PolymerEntity

const search = new SearchRequest();
search.request(search_query);

Search metadata class provides the searchable paths and methods for the RCSB Search API

import {RcsbSearchMetadata} from "@rcsb/rcsb-api-tools/build/RcsbSearch/Types/SearchMetadata";

E.g. RcsbSearchMetadata.RcsbEntryInfo.DiffrnResolutionHigh.Value.path attribute contains the string "rcsb_entry_info.diffrn_resolution_high.value"

E.g. RcsbSearchMetadata.RcsbEntryInfo.DiffrnResolutionHigh.Value.operator enumerates the possible comparison operations (i.e. Equals, Greater, Range, ...)

Search enums provide a collection of enums/classes that provide a controlled vocabulary to build the RCSB Search queries. The name of each enum/class (camel cased) matches with the RCSB search schema field name in snake case format. E.g. import {AggregationType, Operator, ReturnType, Service} from "@rcsb/rcsb-api-tools/build/RcsbSearch/Types/SearchEnums";

AggregationType encodes the possible values of the schema field "aggregation_type", i.e. AggregationType.Terms = "terms", AggregationType.Histogram = "histogram", ...

• GraphQL types can be generated from specific URLs. By default, production server are used
  • E.g. npm run buildGraphQLInterfaces -- --data-api http://132.249.210.199/graphql --1d-service http://132.249.213.161/graphql

• DW schemas are collected from rcsb-mojave-model project released in maven.

  • rcsb-mojave-model:target/generated-sources/schema/core

• Search API schemas are collected from the rcsb-arches git repo.

  • rcsb-arches:src/main/resources/schema

• DW schemas

  • npm run downloadDwSchemas -- --schema-version <VERSION-TAG>
  • E.g. npm run downloadDwSchemas -- --schema-version 1.32.1-MODELS-SNAPSHOT

• Search schemas

  • npm run downloadSearchSchemas -- --branch-name <GIT-REMOTE-BRANCH-NAME>
  • E.g. npm run downloadSearchSchemas -- --branch-name dev-computed-models
