# Generate Flow Types

Generate flow types using a schema and a query.

## Design

The generator exports a function that turns a GraphQLSchema and a parsed GraphQL AST into a Babel AST that represents the type structure.

```js
function documentToModule(parent: GraphQLSchema, node: DocumentNode): BabelAST
```

To achieve this the program is composed recursively into functions that solve a subtask of the overall task. This works because the Flow type system and the GraphQL type system are similar enough that sub-solutions can form the overall solution.

## How does this compare to _Apollo Codegen_

[Apollo Codegen](https://github.com/apollographql/apollo-codegen) targets multiple platforms such as Typescript, Scala and Swift. By focusing on flow types this project tries to iterate faster and make customisation in different dimensions easier.

Also teip requires your GraphQL documents to be written inside of pure `.graphql` files. This allows teip to create `.graphql.flow` files next to these files that contain the definitions for the queries inside.

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.
