SAP Cloud SDK for JavaScript Logo


This package contains the generator to create your own service module using a OpenAPI specification. This generator is based on the OpenAPI Tools generator for OpenAPI and adds some additional code for convenience to better integrate with the SAP Cloud SDK.


$ npm install @sap-cloud-sdk/openapi-generator

To run the CLI locally, compile and link the package.

$ yarn install

$ yarn compile

$ npm link

$ openapi-generator help

Usage (CLI)

Generate OpenAPI client(s), that use the connectivity features of the SAP Cloud SDK for JavaScript/TypeScript.

Usage: openapi-generator --input <input> --outputDir <outputDirectory>

--help Show help [boolean]
--version Show version number [boolean]
-i, --input Specify the path to the directory or file containing
the OpenAPI service definition(s) to generate clients
for. Accepts Swagger and OpenAPI definitions as YAML
and JSON files. Throws an error if the path does not
exist. [string] [required]
-o, --outputDir Specify the path to the directory to generate the
client(s) in. Each client is generated into a
subdirectory within the given output directory.
Creates the directory if it does not exist. Customize
subdirectory naming through `--optionsPerService`.
[string] [required]
-t, --transpile Transpile the generated TypeScript code. When enabled
a default `tsconfig.json` will be generated and used.
It emits `.js`, `.js.map`, `.d.ts` and `.d.ts.map`
files. To configure transpilation set `--tsconfig`.
[boolean] [default: false]
--include Include files matching the given glob into the root
of each generated client directory. [string]
--overwrite Allow to overwrite files, that already exist. This is
useful, when running the generation regularly.
[boolean] [default: false]
--clearOutputDir Remove all files in the output directory before
generation. Be cautious when using this option, as it
really removes EVERYTHING in the output directory.
[boolean] [default: false]
--skipValidation By default, the generation fails, when there are
duplicate or invalid names for operations and/or path
parameters after transforming them to camel case. Set
this to true to enable unique and valid name
generation. The names will then be generated by
appending numbers and prepending prefixes.
[boolean] [default: false]
--tsConfig Replace the default `tsconfig.json` by passing a path
to a custom config. By default, a `tsconfig.json` is
only generated, when transpilation is enabled
(`--transpile`). If a directory is passed, a
`tsconfig.json` file is read from this directory.
--packageJson When enabled, a `package.json`, that specifies
dependencies and scripts for transpilation and
documentation generation is generated.
[boolean] [default: false]
-v, --verbose Turn on verbose logging. [boolean] [default: false]
--optionsPerService Set the path to a file containing the options per
service. The configuration allows to set a
`directoryName` and `packageName` for every service,
identified by the path to the original file. It also
makes sure that names do not change between generator
runs. If a directory is passed, a
`options-per-service.json` file is read/created in
this directory. [string]
-c, --config Set the path to a file containing the options for
generation instead of setting the options on the
command line. When combining the `config` option with
other options on the command line, the command line
options take precedence. If a directory is passed, a
`config.json` file is read from this directory.

Usage (programmatically)

import { generate } from '@sap-cloud-sdk/openapi-generator';

// initialize generator options based on what you want to do
// note that inputDir and outputDir are mandatory
const options: GeneratorOptions = {
inputDir: 'path/to/inputDir',
outputDir: 'path/to/outputDir'

// generates the files and writes them to the outputDir
await generate(options);
