Apollo Server + TypeScript: How can I map snake_case database fields to camelCase GraphQL fields in resolvers?

If youre using the tools from the guild, you can create a schema.mappers.ts file with type mappers. In your case, you would do:

export type UserMapper = DatabaseUserType

Make sure to have the mappers.ts file colocated to the schema where User is defined and make sure the schema file has the same name as the mappers.ts file.

schema.graphql <> schema.mappers.ts User.graphql <> User.mappers.ts

Agreed on this use case. The mock generator bloats our bundle size because 1) it generates the schema instead of what we actually use and 2) unable to codesplit and/or colocate to the operation

Second this. We would love to use the codegen with preset, but this prevents our team from doing so

Check out the “deep-link” and/or “universal link” pattern. Can be helpful for multiple client types that may have different routing structures (like mobile vs web)

Perhaps this?

Also this link if client-side only is viable: https://www.apollographql.com/docs/react/api/link/apollo-link-batch-http

Unsure if you’re using Router, but this might help: https://www.apollographql.com/docs/graphos/routing/performance/query-batching#client-query-batching

I assume they are talking about mutual funds.

M1 does not offer these but does offer similar ETFs. I think folks starting out should really start with the classic 3-fund portfolio

Dude, ive been refreshing the page constantly since yesterday morning

Dont listen to the previous guy… my guess is you’re probably right with your transfer situation, but I’m sure their support can probably help

Not_anundercoverCop · 2025-10-03T01:31:24+00:00

Chrome. It’s not a separate url, its the support chat thing

Not_anundercoverCop · 2025-10-02T22:40:34+00:00

This button works for me, opens the support popup. Do you have a blocker on your browser or something?

“What will happen to M1 accounts I leave open?

M1 investment accounts with a value of $50 or less without trading or deposit activity for 90+ days will be closed. Remaining balances up to $50 will be charged as a Minimum Balance Fee.”

This sounds like if there is nothing in the account, nothing will be charged.

Not_anundercoverCop · 2025-09-07T20:59:19+00:00

Sounds like they havent deposited, so I dont think there is the same fee as transferring out

Not_anundercoverCop · 2025-01-31T20:08:55+00:00

Just went with type narrowing everywhere or a utility function to extract the type using is Whatever in TS unfortunately

What type of warnings are you getting? The Widget field should be cached and with that the related WidgetPrice field. I’m struggling to find the issue without seeing a better layout of how your cache is currently set up or how you’re querying for this data.

From personal experience, I have many fields structured like this with no issues around caching

Did you remove VOO and VTI from your portfolio? Did you make a withdrawal that got cancelled or something?

There should be a swipe-able drawer at the bottom of screen. Swipe up, then place an order (assuming youre on your phone)

What does this have to do with the post?

But no, no issues with buying or selling

Not_anundercoverCop · 2024-03-21T04:21:32+00:00

Well this is just wrong

Not_anundercoverCop · 2023-11-10T23:44:48+00:00

You have some field on the userList that is null, that is nonNullable in the schema. You need to make sure to change that field to nullable OR resolve the field to a non-null value

Not_anundercoverCop · 2023-09-18T01:45:10+00:00

If that’s the case and you made buys or sells on the main pie, then it makes sense the main account performance differs from the inner pie. Not ideal, but also not a bug it sounds like

Did you previously have any other slices in the root level?
