@har-sdk/editor v1.5.12

@har-sdk/editor

Parses OAS and Postman API specification files into form of tree with endpoints and parameters as leaves; tree is useful for GUI representation of specification parameters

Each node and parameter value have JSON pointer, that could be used to change parameter value or to remove node.

Setup

npm i --save @har-sdk/editor

Usage

import { OasV3Editor, SpecTreeNode } from '@har-sdk/editor';

const openApiEditor = new OasV3Editor();
openApiEditor.setup(jsonOrYamlSourceString).then(() => {
  // tree parsing
  let tree: SpecTreeNode = openApiEditor.parse();

  // setting/updating parameter value
  tree = openApiEditor.setParameterValue(
    // parameter `valueJsonPointer` is pointer to `example` for oas3 and `default` for oas2;
    // referenced parameter will be dereferenced automatically
    tree.parameters[0].valueJsonPointer,
    someNewValue
  );

  // removing specific node
  tree = openApiEditor.removeNode(tree.children[1].jsonPointer);

  // serialization
  const serializedUpdatedSpec = openApiEditor.stringify();
});

API

Available editors

• OasV2Editor
• OasV3Editor
• PostmanEditor

All of them implement both TreeParser and Editor interfaces.

API interfaces

export interface TreeParser {
  setup(source: string): Promise<void>;
  parse(): SpecTreeNode;
  stringify(): string;
}

export interface Editor {
  setParameterValue(jsonPointer: string, value: any): SpecTreeNode;
  removeNode(jsonPointer: string): SpecTreeNode;
}

Tree node interfaces

export interface SpecTreeNode {
  readonly path: string;
  readonly name?: string;
  readonly method?: HttpMethod;
  readonly jsonPointer: string;
  readonly children?: ReadonlyArray<SpecTreeNode>;
  readonly parameters?: ReadonlyArray<SpecTreeNodeParam>;
}

export interface SpecTreeNodeParam {
  readonly paramType: 'location' | 'requestBody' | 'variable';
  readonly value?: any;
  readonly valueJsonPointer: string;
}

// Specific parameter types with specific properties

export interface SpecTreeNodeVariableParam extends SpecTreeNodeParam {
  readonly paramType: 'variable';
  readonly name: string;
}

export interface SpecTreeNodeLocationParam extends SpecTreeNodeParam {
  readonly paramType: 'location';
  readonly name: string;
  readonly location: ParamLocation;
}

export interface SpecTreeRequestBodyParam extends SpecTreeNodeParam {
  readonly paramType: 'requestBody';
  readonly bodyType: string;
}

// Enums

export enum ParamLocation {
  PATH = 'path',
  QUERY = 'query',
  HEADER = 'header',
  BODY = 'body'
}

export enum HttpMethod {
  GET = 'GET',
  PUT = 'PUT',
  POST = 'POST',
  DELETE = 'DELETE',
  OPTIONS = 'OPTIONS',
  HEAD = 'HEAD',
  PATCH = 'PATCH',
  TRACE = 'TRACE'
}
