How to use

If you would like to change something pre or post our API logic, then use this method.

import SuperTokens from "supertokens-node";
import ThirdPartyEmailPassword from "supertokens-node/recipe/thirdpartyemailpassword";

SuperTokens.init({
appInfo: {
apiDomain: "...",
appName: "...",
websiteDomain: "..."
},
supertokens: {
connectionURI: "...",
},
recipeList: [
ThirdPartyEmailPassword.init({
override: {
apis: (originalImplementation) => {
return {
...originalImplementation,

// here we only override the email & password sign up API logic
emailPasswordSignUpPOST: async function (input) {
if (originalImplementation.emailPasswordSignUpPOST === undefined) {
throw Error("Should never come here");
}

// TODO: some pre sign up logic

let response = await originalImplementation.emailPasswordSignUpPOST(input);

if (response.status === "OK") {
// TODO: some post sign up logic
}

return response;

},
// ...
// TODO: override more apis
}
}
}
})
]
});
  • originalImplementation is an object that contains apis that have the original implementation for this recipe. They can be used in your custom apis as a way to use the SuperTokens' default behaviour.
  • In the above code snippet, we override the emailPasswordSignUpPOST api of this recipe. This api will be used to handle the email password sign up requests.
