NestJS - GraphQL not working in my jest E2E "is not a function"

Asked 2022-Feb-20 at 14:45

It's 3 days i am on this problem of E2E tests on my GraphQL application with NestJS + Apollo / Express.

When I am running my app with serverless offline or directly with my main file, it's working perfectly. I have my graph and all things I need :)

But, when I am running E2E tests with Jest, I received an error from the await app.init() inside the beforeEach.

After playing with the package.json and dependencies, the error throwed is TypeError: (0 , schema_1.makeExecutableSchema) is not a function.

Someone have any idea please ? I am totally blocked ... :(

After many hours of intense programming ... I finally found the problem.

Be careful if you use some "alias" for imports, because it can overwrite some of the packages used.

Here, i use the @graphql alias, and it breaks all my tests. When I remove it, the problem disappear.

How to get full AST representation of union type in typescript?

I know about ts-ast-viewer but I don't know how they extract list of elements from the union.

I have tried several existing solutions, including this and it seems that most of them are obsolete. Some ts.[methods] are deprecated now.

This is initial code to start debug compiler API:

Answered 2022-Jan-31 at 16:46

You can't use the AST for this because the AST only contains information about what the text looks like in the file and not how parts of the code relate to other parts. You'll need to use the type checker for that. Here's a self contained example:

QUESTION

Injecting ObjectionJS model using NestJS throws exception

Asked 2021-Nov-18 at 19:01

When I try to inject an Objection.js model into a NestJs service:

constructor(@Inject('UserModel') private readonly modelClass: ModelClass) {}

I get an Maximum call stack size exceeded error at compile time. I thought it was due to my other models and some circular dependency. I removed everything outside of a lone model and still get the exception.

If I set "strict": true in tsconfig.json, the code builds and runs as expected. How do I remedy this situation?

Below are the models and the packages used.

According to this issue Typescript must be ran in strict mode to transpile the code correctly. Seems Objection v3 is still in some pre-release state so this isn't quite documented yet.

Apparently, the type of GraphQLError.originalError was changed at some point from originalError?: Maybe to Error | undefined. Downgrading to graphql 15.3.0 solved this for me.

Asked 2021-Sep-27 at 09:16

The carousel does not move, it already initializes, check the libraries it is in perfect order; but even so it does not move by itself and not by touching the buttons.

I have the latest version of the owlCarousel and jquery library.

I tried updating libraries and I also tried using the min and normal libs. I did not make any progress.

TypeScript Syntax Validation with Ace Editor / Any Web IDE?

Asked 2021-May-19 at 06:44

Google has failed me. I'd like a way to have TypeScript syntax validation in my Ace editor. I've found an Ace-based TypeScript Playground by basarat AKA 'That TypeScript Guy' but the repo has no good README and I doubt the validator is up to date with TypeScript's newer features, as the last commit is from years ago.

I understand how to add the custom listing itself in Ace; it's just the actual TypeScript linter I am struggling to find. It seems there is no up-to-date maintained one; I'm surprised there isn't one. Currently, I debounce a call to get diagnostics via a library called ts-morph, which provides developer-friendly methods for the TypeScript compiler API. I get those diagnostics, loop over them, and add my own custom annotations to the editor:

Since the behaviour change in TS 4.2, the best thing I can figure out so far is to traverse the AST and inspect the type node of the type alias. There might be a better way though...

Use TypeScript Compiler API to get the Type Alias Declaration Node from a Type Reference Node

I am working with ts-morph which in turns uses the TS Compiler API.

I have this case of code:

...

ANSWER

Answered 2020-Nov-09 at 05:08

It's not possible in this specific situation. The TypeScript compiler interns certain types for performance reasons.

For performance reasons, we intern types where possible (this way we avoid duplicating work for equivalent types). We do not currently intern anonymous object types, though we've experimented with it before. Unfortunately, interning object types has the side effect of breaking go to definition on the interned types; so we didn't pull it in. The specific types we intern today are indexed accesses, unions, and intersections (also reverse mapped types, but only inference can produce those). This is a tradeoff - origin information is lost on interned types; but we do avoid quite a bit of work most of the time. - Source

So here, Foo is being interned as string since they're equivalent. I asked in the TypeScript repo if it would be feasible to disable this behaviour for analysis reasons, but didn't get a response yet.

One trick you can do to get this to work is change the code to use a brand instead of only string.
