Unable to find CLI package openapi-ts-rest on NPM repository

[jpierson-at-riis]

I tried running the example from the README.md but I got the following error.

npx openapi-ts-rest path/to/openapi-spec.yaml -o path/to/output/dir

npm error code E404
npm error 404 Not Found - GET https://registry.npmjs.org/openapi-ts-rest - Not found
npm error 404
npm error 404  'openapi-ts-rest@*' is not in this registry.
npm error 404
npm error 404 Note that you can also install from a
npm error 404 tarball, folder, http url, or git url.
npm error A complete log of this run can be found in: /root/.npm/_logs/2025-07-30T16_58_53_008Z-debug-0.log

It looks like this package doesn't exist on the npm registry. Maybe it was and has been removed?

Are you running the command inside a project folder with the cli installed on?

[jpierson-at-riis]

@Carminepo2, I'm not 100% following your question but I'll try to provide another example which yields the same error.

$ npm install --save-dev openapi-ts-rest
npm error code E404
npm error 404 Not Found - GET https://registry.npmjs.org/openapi-ts-rest - Not found
npm error 404
npm error 404  'openapi-ts-rest@*' is not in this registry.
npm error 404
npm error 404 Note that you can also install from a
npm error 404 tarball, folder, http url, or git url.
npm error A complete log of this run can be found in: /root/.npm/_logs/2025-07-31T23_58_38_990Z-debug-0.log

So you can see that npm is unable to find openapi-ts-rest in the registry. Directly searching NPM or following the URL registry.npmjs.org/openapi-ts-rest will give a similar 404 status error.

I don't think it's related to anything with node or npm on my side by just in case I've included the versions of each of these executables below.

$ node --version
v22.15.1
$ npm --version
10.9.2

As a workaround I'm using this basic NodeJS script.

import { generateContract } from "@openapi-ts-rest/core";
import fs from "fs";

const result = await generateContract({ openApi: "openapi.yaml" });
fs.writeFileSync("generated.ts-rest.ts", result);

I'd rather not manage another script for doing this per project, but this workaround has allowed me to explore and test the generated results of this project further which so far, I'm very happy with.
