Node‐Fetch Support

By default, this tool will generate a client that is compatible with the (browser based) Fetch API. However, this client will not work inside the Node.js environment. If you want to generate the Node.js compatible client then you can specify --client node in the openapi call:

openapi --input ./spec.json --output ./generated --client node

This will generate a client that uses node-fetch internally. However, in order to compile and run this client, you might need to install the node-fetch@2.x dependencies.

Since version 3.x node-fetch switched to ESM only, breaking many CommonJS based toolchains (like Jest). Right now we do not support this new version!

npm install @types/node-fetch@2.x --save-dev
npm install abort-controller@3.x --save-dev
npm install form-data@4.x --save-dev
npm install node-fetch@2.x --save-dev

In order to compile the project and resolve the imports, you will need to enable the allowSyntheticDefaultImports in your tsconfig.json file.
