ProtoSchema API Reference

Content

  • ProtoSchema
    • addSchemas adds JSON Schemas objects to the available set to be encoded
    • encode encodes JSON Schemas to Protobuf definitions

ProtoSchema

import { ProtoSchema, IEncoderOptions } from 'protoschema';

const encoderOptions: IEncoderOptions = {};

const protoschema: ProtoSchema = new ProtoSchema(encoderOptions);

ProtoSchema is the main class of this package that encapsulates all the functionalities to encode JSON Schemas to Protobuf 3 definitions.

Options

  • encoderOptions.nullKeyPrefix - The prefix to be concatenated to properties name to identify null values in protobufs messages. To disable this feature you can specify this property as null.

addSchemas

import { IJSONSchemaProto } from 'protoschema';

const schemas: Array<IJSONSchemaProto> = [];

protoschema.addSchemas(...schemas);

This method adds schemas to the available set to be encoded to protobuf definitions.

Options

  • ...schemas - JSON Schema objects to be added.

Returns

A reference to the ProtoSchema instance itself.

encode

const selectors: Array<string> = [];

const encoded: { [key: string]: string } = protoschema.encode(...selectors);

This method encodes selected schemas to protobuf defintions separated by namespaces.

Options

  • ...selectors - JSON Schema selectors to pick schemas to be parsed. Each selector can be:
    • The schema's $namespace and $id concatenated with a dot as glue to encode just the selected schema and the referenced schemas.
    • The schema's $namespace to encode all schemas from the specified namespace.
    • The schema's $id if the specified schema doesn't have a namespace (note that the returned object will contain the default attribute with the encoded result).

Returns

An object where keys are the encoded namespaces and values are the protobuf definitions.
