[@hono/zod-openapi] Error with testing about middleware

[monoald]

Hi @nicobytes!

To fix this you need to config babel

• Install babel:

npm install --save-dev @babel/core @babel/node @babel/preset-env

• Add the config on babel.config.js:

module.exports = {
  presets: ["@babel/preset-env"]
};

• Add the new transform pattern to jest.config.js:

{
    ...
    transform: {
        '^.+\\.(ts|tsx)$': 'esbuild-jest',
        '^.+\\.js$': 'babel-jest',
    },
}

• Then add in ignore patterns the package that is causing the error, (also in jest.config.js):

{
    ...
    transformIgnorePatterns: [ "node_modules/(?!(yaml/browser))" ],
}

This is the only workaround I found that works

Hi! @monoald!

Thanks for your reply and yes, the key is :

{
    ...
    transformIgnorePatterns: [ "node_modules/(?!(yaml/browser))" ],
}

Because I tried the same configuration but without that last part and on the other hand I tried with vitest and it just works!
