Walkthrough

This update introduces several stylistic and configuration changes, including converting double-quoted strings to single quotes across multiple files, updating Jest and TypeScript configurations, and adding type declarations for the @huggingface/transformers module. It also enhances robustness in model code with additional validation checks and adjusts the handling of input token types in pipeline functions. Additionally, it adds comprehensive tests for the Base model and modifies CI workflows by removing the web build job.

Poem

In the warren of code, where carrots abound,
Single quotes now hop all around.
Type roots are mapped, new docs soon to sprout,
Mocks cleaned and robust checks rolled out.
With pipelines and models, all neat and precise—
This rabbit says: “Ship it! The code is quite nice!” 🥕

tsconfig.json (1)

7-7: LGTM! TypeScript configuration correctly updated.

The addition of typeRoots properly supports custom type declarations while maintaining the standard @types directory. This aligns well with the PR's goal of adding type declarations for @huggingface/transformers.

jest.config.js (1)

4-7: LGTM! Jest configuration properly updated for CI stability.

The modulePathIgnorePatterns addition correctly excludes the example project's node_modules and build output directory, which should prevent module resolution conflicts during testing.

example/App.tsx (2)

1-11: LGTM! Stylistic consistency improved.

The conversion from double quotes to single quotes throughout the file improves code consistency and aligns with the project's style standards.

Also applies to: 15-15, 24-24, 29-29, 36-36, 40-40, 52-52, 55-55, 58-58, 64-64, 95-96, 100-100


31-31: Verify file path construction change.

The file path construction appears to have been simplified from including the preset name (${preset.name}_${fileName}) to just the filename. This could cause files from different presets with the same filename to overwrite each other, potentially breaking caching functionality.

Please verify if this change was intentional by running:

#!/bin/bash
# Check if the preset name was previously included in the file path
rg -A 5 -B 5 'documentDirectory.*fileName' example/
src/__tests__/text-embedding.model.test.tsx (1)

1-2: LGTM! Test file stylistic consistency improved.

The conversion from double quotes to single quotes throughout the test file improves code consistency while maintaining all test functionality intact.

Also applies to: 4-4, 15-15, 19-19, 21-21, 25-25, 34-34, 38-38

src/__tests__/text-embedding.pipeline.test.tsx (2)

6-11: LGTM! Mock implementation formatting improved.

The refactoring from chained .fn() calls to a single .fn().mockImplementation() call is more readable and maintainable while preserving the same mock behavior.


1-48: ```shell
#!/bin/bash

Locate and display the TextEmbeddingPipeline implementation

18-20: Static-only AutoTokenizer class violates noStaticOnlyClass lint – switch to namespace or interface

The declaration is purely static, so ESLint/Biome flags it.
Typical ambient typings expose this as a namespace or a function:

-export class AutoTokenizer {
-  static from_pretrained(model_name: string): Promise<PreTrainedTokenizer>;
-}
+export namespace AutoTokenizer {
+  function from_pretrained(model_name: string): Promise<PreTrainedTokenizer>;
+}

This keeps the external API identical while satisfying the lint rule and avoiding the (misleading) new AutoTokenizer() possibility.

In the real HF tokenizer API the flag is return_tensors (plural) and accepts values such as 'pt' | 'tf' | 'np' – not a boolean. Using the singular form & a boolean type may let silent type-mismatches leak into runtime.

-        return_tensor?: boolean;
+        /**
+         * Framework in which tensors should be returned (`'pt' | 'tf' | 'np'`)
+         * Matches the official HF signature.
+         */
+        return_tensors?: 'pt' | 'tf' | 'np';

12-15: Consider making decode asynchronous for parity with upstream JS

Some HF JS tokenizers expose decode as an async method returning a Promise<string>.
If the concrete implementation you mock later is async, tightening the signature now will prevent accidental await omissions.

-  ): string;
+  ): Promise<string>;

1-27: Overall declaration adds useful type-safety

The ambient module neatly covers the subset of HF features the codebase uses and unblocks CI. Other than the minor nits above, the structure looks solid.

54-57: Fix indentation issues

Remove extra spaces for consistent formatting.

-    mockFetch = jest.fn();
-    
+    mockFetch = jest.fn();
+
     // Setup default mock responses
-    mockFetch.mockResolvedValue('mock-model-path');
-    
+    mockFetch.mockResolvedValue('mock-model-path');

277-313: Improve error message formatting for readability

Format error messages on new lines for better readability in test failures.

-      expect(() => model.callArgmax(mockTensor)).toThrow('Invalid tensor dimensions');
+      expect(() => model.callArgmax(mockTensor)).toThrow(
+        'Invalid tensor dimensions'
+      );

Apply similar formatting to lines 286, 295, 304, and 313.


351-351: Use dot notation for better readability

-      expect(feed['logits']).toBeUndefined();

1-45: LGTM! Well-structured test harness

The TestableBase class provides clean access to protected members for testing without modifying the production code.


1-523: Excellent test coverage and structure!

This test suite provides comprehensive coverage of the Base model functionality, including:

  • Proper validation of the enhanced argmax method with dimension and value checks
  • Thorough testing of the safer updateKVCache implementation
  • Good edge case coverage
  • Proper resource cleanup and error handling

The tests effectively validate the robustness improvements mentioned in the AI summary.

23-32: Consider using a more type-safe approach to access private properties.

The use of (this as any) to access private properties breaks type safety. While necessary for testing, consider defining protected getters in the base class or using a testing utility that preserves type safety.

- public getKvDims() {
-   return (this as any).kv_dims;
- }
+ public getKvDims(): number[] {
+   return (this as any).kv_dims;
+ }

156-164: Misleading comment in argmax test.

The test logic is correct, but the comment is misleading. The test data is [0.1, 0.2, 0.8, 0.3, 0.4, 0.5] with dims [1, 2, 3]. The argmax function looks at the last sequence starting at index 3: [0.3, 0.4, 0.5]. The maximum value 0.5 is at relative index 2, not 0.8.

- expect(result).toBe(2); // Index of 0.8 in the last sequence
+ expect(result).toBe(2); // Index of 0.5 (max value) in the last sequence

166-174: Misleading comment in negative values test.

Similar issue with the comment. The test examines the last sequence [-0.1, -0.3, -0.4] where -0.1 is the maximum at relative index 0.

- expect(result).toBe(0); // Index of -0.1 in the last sequence
+ expect(result).toBe(0); // Index of -0.1 (max value) in the last sequence  

405-414: Remove commented-out test code.

Commented-out test code should be removed to maintain code cleanliness. If these tests are needed later, they can be tracked in issues or TODO comments.

- /*
- it('should handle load with proper mocking setup', async () => {
-   // ... complex mocking test code ...
- });
-
- it('should handle load without external data', async () => {
-   // ... complex mocking test code ...
- });
- */

254-266: Potential issue with tensor reuse in updateKVCache test.

The same newTensor instance is used for both key and value in the outputs, which may not reflect realistic usage patterns. Consider using separate tensor instances to better simulate actual model outputs.

- const newTensor = new Tensor('float32', [], [1, 8, 10, 64]);
- const outputs = {
-   'present.0.key': newTensor,
-   'present.0.value': newTensor,
-   'logits': new Tensor('float32', [], [1, 1, 1000]),
- };
+ const keyTensor = new Tensor('float32', [], [1, 8, 10, 64]);
+ const valueTensor = new Tensor('float32', [], [1, 8, 10, 64]);
+ const outputs = {
+   'present.0.key': keyTensor,
+   'present.0.value': valueTensor,
+   'logits': new Tensor('float32', [], [1, 1, 1000]),
+ };

54-74: Good mocking setup for global fetch and model configuration.

The mock setup properly simulates the expected JSON configuration structure and byte array conversion that the load method expects.


443-470: Excellent integration test with proper mocking.

This test effectively verifies the complete load method flow with proper URL generation and model configuration. The assertions correctly validate both the fetch calls and the resulting model state.


100-153: Comprehensive initializeFeed test coverage.

The tests thoroughly cover different scenarios including GPU buffer disposal, different data types, and edge cases. The test structure and assertions are well-designed.

22-32: Consider using a more type-safe approach for accessing private properties.

The repeated use of (this as any) to access private properties bypasses TypeScript's type safety. While necessary for testing, consider making these properties protected in the base class if they need to be tested, or use reflection-based approaches.

  public getKvDims() {
-   return (this as any).kv_dims;
+   return this['kv_dims' as keyof this];
  }

  public getNumLayers() {
-   return (this as any).num_layers;
+   return this['num_layers' as keyof this];
  }

  public getDtype() {
-   return (this as any).dtype;
+   return this['dtype' as keyof this];
  }

216-216: Fix typo in error message.

The error message contains a typo: "infinitive" should be "infinite".

- 'found infinitive in logits'
+ 'found infinite in logits'

Note: This also needs to be fixed in the actual implementation in src/models/base.tsx.


54-74: Consider extracting mock configuration to improve maintainability.

The mock setup is complex and duplicated. Consider extracting the mock configuration into helper functions or constants to improve maintainability and reduce duplication.

const createMockConfig = () => ({
  eos_token_id: 2,
  num_key_value_heads: 8,
  hidden_size: 512,
  num_attention_heads: 8,
  num_hidden_layers: 12,
});

const setupMockFetch = (config = createMockConfig()) => {
  return jest.fn().mockResolvedValue({
    arrayBuffer: () =>
      Promise.resolve(
        Uint8Array.from(
          JSON.stringify(config)
            .split('')
            .map((c) => c.charCodeAt(0))
        ).buffer
      ),
  });
};

1-507: Excellent test coverage with comprehensive edge case handling.

This test suite provides thorough coverage of the Base model class with well-structured tests covering:

  • Constructor initialization
  • Feed tensor management and GPU buffer disposal
  • Argmax computation with various edge cases
  • Key-value cache updates
  • Session release behavior
  • Integration testing with mocked dependencies

The use of a TestableBase wrapper to expose protected methods is a good testing pattern, and the edge case coverage (NaN/Infinity values, invalid dimensions, etc.) is particularly thorough.

🛠️ Refactor suggestion

Replace placeholder test with meaningful assertion or remove it.

This test doesn't verify any specific functionality related to URL generation. Either implement a direct test for the getHuggingfaceUrl function or remove this placeholder.

- it('should generate correct Hugging Face URL', () => {
-   // This is tested indirectly through the load method in other tests
-   expect((global as any).fetch).toBeDefined();
- });

Consider adding a direct test for URL generation instead:

it('should generate correct Hugging Face URL', () => {
  // Import and test getHuggingfaceUrl directly
  const url = getHuggingfaceUrl('microsoft/DialoGPT-medium', 'config.json');
  expect(url).toBe('https://huggingface.co/microsoft/DialoGPT-medium/resolve/main/config.json');
});

In src/__tests__/base.model.test.tsx around lines 346 to 350, the current test
only checks if fetch is defined and does not verify the functionality of
generating a Hugging Face URL. Replace this placeholder test with a direct test
of the getHuggingfaceUrl function by importing it and asserting that it returns
the expected URL string for given inputs, or remove the test entirely if not
needed.
