Version 18.0.0

Major

• Updated Node.js support to ^22.13.0 || ^24.0.0 || >=26.0.0.

• Updated the optional peer dependency @types/express to ^5.0.0.

• Updated the optional peer dependency @types/koa to ^3.0.0.

• Updated the peer dependency graphql to ^17.0.0.

• Migrated the scalar GraphQLUpload to the graphql v17 scalar method names:

  • parseValue → coerceInputValue.
  • parseLiteral → coerceInputLiteral.
  • serialize → coerceOutputValue.

• Changed imports from graphql to deep imports, for slightly more optimal JavaScript module design. This can be further improved once graphql/graphql-js#4442 is implemented.

• The type FileUpload is no longer re-exported from graphql-upload/GraphQLUpload.mjs. To migrate TypeScript type imports:

  - import type { FileUpload } from "graphql-upload/GraphQLUpload.mjs";
  + import type { FileUpload } from "graphql-upload/processRequest.mjs";

Patch

• Removed the package field devEngines as the development and runtime supported Node.js versions are the same again.
• Updated package scripts.
• Updated GitHub Actions CI config:
  • Improved the triggers.
  • Renamed the job tests to test.
  • Run tests with the lower and upper bounds of each supported major Node.js version.
  • Removed conditionality for Node.js < v22 support.
• Removed no longer necessary polyfills for global File, Promise.withResolvers, and Request.prototype.bytes in tests.
• Removed no longer necessary Node.js version conditionality in tests.
• Refactored tests from describe and it to suite and test.
• Implemented a new test helper function serverClose to ensure tests await the proper closing of servers and all connections, speeding up test runs (particularly in older Node.js versions).
• Added an end-to-end test.
• Added a .gitattributes file to enforce LF line endings.
• Sorted config in .editorconfig.
• Edited the changelog for consistency.
