Question

How to modify the response object after singin login request because the default response is email timejoined and superTokenId I want the id of the user not the supertoken id as well How can I change this behavior

rp · Answer

hey

rp · Answer

if not the supertokens id which ID are you talking about

rp · Answer

which recipe are you using

John Oliver · Answer

ThirdPartyEmailPassword

rp · Answer

see this https supertokens com docs thirdpartyemailpassword advanced customizations apis override custom response api override

John Oliver · Answer

Are signup and signin methods implemented in the same function The both use the same methods

rp · Answer

for social login yea Not for email password

John Oliver · Answer

```override apis originalImplementation any => return originalImplementation emailPasswordEmailExistsGET async function input input options res sendJSONResponse message my custom response return status OK exists false emailPasswordSignUpPOST async function input any if originalImplementation emailPasswordSignUpPOST === undefined throw Error Should never come here const formFields any = input formFields const inputObject any = for let index = 0 index < formFields length index++ const element = formFields index inputObject element id = element value const email firstName lastName phoneNumber = inputObject First we call the original implementation of signUpPOST const response any = await originalImplementation emailPasswordSignUpPOST input response user = response user email firstName lastName phoneNumber console log response return response ``` I have tried this but this is not working for me

rp · Answer

you also need to set the status code

rp · Answer

for example like this ``` input options res setStatusCode 200 or any other status code input options res sendJSONResponse message my custom response ```

John Oliver · Answer

```emailPasswordEmailExistsGET async function input input options res setStatusCode 200 input options res sendJSONResponse message my custom response return status OK exists false ``` This is not working I am still getting the id that is generated by supertoken timeJoined and email only

rp · Answer

Can you add a console log right before you set the 200 status code Does that get printed out

rp · Answer

Also what do you meant by getting the id generated by supertokens This is a different api that you are overriding Not the sign in sign up api Im confused

John Oliver · Answer

I added console log before the 200 status code and I got nothing in the console

John Oliver · Answer

This is the response I am getting ``` status OK user email mitulkheni695 gmail com id 37ffadc9 3002 48g4 95bc 5230a44c5b47 timeJoined 1673798066293 ``` look at the id now It is generated by supertoken library I have another method in my nest app that saves the user data on signup signin method in the postgres database I want to get that id that is auto generated primary key like 1 2 3 etc in the response

John Oliver · Answer

I have this code in my app ```supertokens init appInfo this config appInfo supertokens connectionURI this config connectionURI apiKey this config apiKey recipeList ThirdPartyEmailPassword init providers ThirdPartyEmailPassword Google clientSecret TODO GOOGLE CLIENT SECRET clientId signUpFeature formFields id firstName id lastName id phoneNumber override apis originalImplementation any => return originalImplementation emailPasswordSignUpPOST async function input any if originalImplementation emailPasswordSignUpPOST === undefined throw Error retrieving data from input and saving logic goes here emailPasswordEmailExistsGET async function input input options res setStatusCode 200 input options res sendJSONResponse message my custom response return status OK exists false ```

John Oliver · Answer

OK I have tried it from the frontend Now I am getting the log on the signup method but I am not getting the log on the signin request

rp · Answer

hey < John Oliver> im really confused about what you want to do here Maybe re explain please

John Oliver · Answer

Does supertokens creates its tables in the database whenever user signs up or signs in

rp · Answer

it adds a row to the table Yes

John Oliver · Answer

OK apart from auto generated table by supertoken I have my own implementation of saving users in the database and that is a different table Do you get that

rp · Answer

yes

John Oliver · Answer

Good now I want to get the users id primary key that is auto generated by postgres from the tables that I have implemented not the supertokens generated tables

John Oliver · Answer

Now Whenever user signs in he will pass the supertoken id in the request Is that Correct

rp · Answer

right So what you want to do is to do user ID mapping of supertokens and your external user ID in the sign up override in override functions config

rp · Answer

< jscyo> can help here

John Oliver · Answer

Yes because I have another functionalities as well in my app where only authorized user can save the data in the database I do not want to save that long super token id in my other tables I want to save the user id that is generated by postgres database by my own implementation

jscyo · Answer

Hey < John Oliver> you can map the userId generated by the postgres database to your supertokens Id by adding the following `SuperTokens createUserIdMapping superTokensUserId SUPERTOKENS USER ID externalUserId POSTGRES USER ID ` to the signUp override code

John Oliver · Answer

Here I have the table called users in the postgres database and there are columns like id primary key auto generated user s details and superToken id This table is my own implementation of user Now How can I do the same that you have mentioned

jscyo · Answer

If you add the function I mentioned above to your `emailPasswordSignUpPOST ` override and pass the auto generated postgres userId and SuperTokens userId to it SuperTokens will now use the postgres userId for the user So all subsequent signIn requests or function calls will return the postgres userId

John Oliver · Answer

Ok

John Oliver · Answer

Sorry but I am confused like where to place this code in my file I have tried it but I am getting an error Can you show with the example You already have some code

jscyo · Answer

Give me a second I will send a snippet to you

John Oliver · Answer

ok

jscyo · Answer

Hey < John Oliver> you can look at this https gist github com jscyo 8a26e4324b6943e1b240fa5259554437 one clarification to make is that you should use the functional override for emailpassword signup

John Oliver · Answer

I have added a comment on that please look at that

lancekey · Answer

This is something I m trying to accomplish as well except I was thinking to store my postgresId as metadata on the user in supertokens

lancekey · Answer

what s the difference between createUserIdMapping and using metadata

rp · Answer

Create user id mapping maps the supertokens user id an external user id that you provide such that logins yield the external user id as opposed to the supertokens user id

rp · Answer

Whereas metadata is just storing any json against a user Id for later retrieval

lancekey · Answer

ok great sounds like createUserIdMapping is what I m looking for then
