@netatwork/odata-edm-generator

This is a CLI-utility to generate OData EDM and endpoints in TypeScript.

Install

npm i -D @netatwork/odata-edm-generator

Usage

# Inline CLI arguments can be used
gen-edm --endpoint https://api.example.com --outputDir out

# A configuration file can be used
gen-edm --config edm-gen.config.js

# Configuration file options can be overridden with inline arguments
gen-edm --config edm-gen.config.js --outputDir out

Check the examples for the generated output.

Options

Options:
  --config       The path to the config file.
  --outputDir    The base output directory to write the generated files.
  --endpoint     The OData endpoint. '{endpoint}' is used to get the list of endpoints, and '{endpoint}/$metadata' is used to get the EDM.
  --quoteStyle   Single or double quote to use; Allowed values are 'single', and 'double'.
  --indentSize   Number of spaces to use for indentation.

`--endpoint`

The OData endpoint for which the code needs to be generated.

Example:

gen-edm --endpoint https://example.com/api/foo --outputDir src/foo

Note that it cannot be combined with endpoints

`--outputDir`

The base output directory. The generator writes the generated files in this directory. When a relative path is used, it is resolved with the current process working directory (process.cwd()).

Example:

gen-edm --endpoint https://example.com/api/foo --outputDir src/foo

`--quoteStyle`

Whether to use single or double quote in the generated files. Allowed values are single (default), and double.

Example:

gen-edm --endpoint https://example.com/api/foo --outputDir src/foo --quoteStyle double

`--indentSize`

The generated files are indented with space. The indentSize can be configured by passing a numeric value for this argument. The default value is 4.

Example:

gen-edm --endpoint https://example.com/api/foo --outputDir src/foo --indentSize 2

`--config`

The path to the configuration (JS) file. The file should export a single object that conforms the generator schema. Below is an example of the file.

module.exports = {
  // base output directory
  outputDir: 'src/generated/',

  // generate code for multiple OData endpoints
  endpoints: [
    {
      url: 'https://example.com/api/foo',
      outputDir: 'intranet-role',
    },
    {
      url: 'https://example.com/api/bar',
      outputDir: 'account-management',
    },
  ],

  quoteStyle: 'double',

  indentSize: 4,
}

The individual configuration options are same as already described above. Only difference is the endpoints property. This array of object can be used to generate EDM for multiple endpoints. The outputDir specified for each endpoint is resolved with the root-level outputDir.

Note that when the --config argument is used, it needs to be the first CLI argument.

Example:

gen-edm --config edm-gen.config.js

Example

This sections shows an elaborate example of the generated code. For more examples check the tests.

Decorators

If you have seen the generated example above, you can see the decorators: @odataEndpoint, and @odataType.

`@odataEndpoint`

It defines a static property on the class named ODataEndpoint that associate the entity endpoint with the class. This is useful when you want to retrieve the entity endpoint inside your generic HTTP pipeline (service class).

Example:

@odataEndpoint(Endpoints.People)
public class Person {
  //...
}

`@odataType`

This is another utility decorator that maps the raw OData type with the generated class. Additionally it also add a friendly enum type to the class. The value of the enum can be used conveniently instead of checking the raw odata type or using the instanceof operator (motivation: instanceof is slower than equality check).

This is particularly useful when dealing with hierarchical complex types. Because as the raw OData datatype gets associated, any serialized JSON of an instance of the generated class contains the OData type annotation, which helps the server to deserialize the data correctly.

Example:

export enum $$StandardConditionTypes {
  BarCondition = 'BarCondition',
  FizzCondition = 'FizzCondition',
  FooCondition = 'FooCondition',
}

export class StandardCondition {
  // omitted for brevity; refer example above.
}

@odataType('#Company.FooService.BarCondition', $$StandardConditionTypes.BarCondition, '$$type')
export class BarCondition extends StandardCondition {
  public readonly $$type: $$StandardConditionTypes;
  // omitted for brevity; refer example above.
}

@odataType('#Company.FooService.FizzCondition', $$StandardConditionTypes.FizzCondition, '$$type')
export class FizzCondition extends StandardCondition {
  // omitted for brevity; refer example above.
}


@odataType('#Company.FooService.FooCondition', $$StandardConditionTypes.FooCondition, '$$type')
export class FooCondition extends StandardCondition {
  // omitted for brevity; refer example above.
}

//-------------
assert(new FooCondition().$$type === $$StandardConditionTypes.FooCondition);
assert(new BarCondition().$$type === $$StandardConditionTypes.BarCondition);
JSON.stringify(new FooCondition()); // {"@odata.type": "#Company.FooService.FooCondition", ... }
JSON.stringify(new BarCondition()); // {"@odata.type": "#Company.FooService.BarCondition", ... }
