In @.mise/config.js.toml:
- Around line 125-128: Add copy steps alongside the existing ORT asset staging
commands to include ort-wasm-simd-threaded.jsep.mjs and
ort-wasm-simd-threaded.jsep.wasm in pkg/ort/, ensuring the WebGPU JSEP runtime
assets are available.
In `@config/deny.toml`:
- Around line 56-64: Remove the RUSTSEC-2026-0258 ignore entry from
config/deny.toml lines 56-64 because bind_rustls_0_23 enables reachable HTTP/2;
regenerate config/osv-scanner.toml and remove its matching ignore entry at line
14. Do not rely on the empty alpn_protocols field in build_tls_server_config to
disable HTTP/2.
In `@services/ws-modules/llm1/src/lib.rs`:
- Around line 76-102: Update stop() so it signals the existing stop flag without
removing it; replace the STOP_FLAG take operation with a borrow that sets the
active session’s Cell to true. Keep STOP_FLAG registered until run() clears it
after chat_workflow returns, preserving is_running() protection against
concurrent sessions.
- Around line 105-141: Restructure chat_workflow so the connection and listener
cleanup runs for both success and error paths: bind the inner setup and
serve_prompts result instead of returning immediately through ? after
client.connect(), and then call listeners.detach() and client.disconnect()
before returning that result. Ensure listener cleanup is also performed when
panel setup fails after attach_panel_listeners succeeds, while preserving the
original error result.
In `@services/ws-server/static/index.html`:
- Around line 35-39: Update the textarea with id chat-input to include an
aria-label that clearly identifies it as the prompt input, while preserving its
existing placeholder and other attributes.
In `@services/ws-server/static/style.css`:
- Around line 179-184: Update the color declaration in the .chat-turn strong
rule to use an alpha value that achieves at least 4.5:1 contrast for the turn
labels, such as 0.82, while preserving the existing typography and layout
styles.

Transformers.js 4.2.0 onnxruntime-web 1.24.3 or 1.27.0 wasmPaths ort-wasm-simd-threaded.jsep WebGPU
💡 Result:
Transformers.js v4.2.0 is a significant release that introduced a new WebGPU runtime rewritten in C++ and deeper integration with ONNX Runtime [1][2]. Compatibility between @huggingface/transformers and onnxruntime-web is critical, as version mismatches often lead to initialization errors such as "no available backend found" [3]. Key Technical Details: 1. Version Compatibility: It is recommended to use the exact version of onnxruntime-web that is specified in the package.json file of the @huggingface/transformers release you are using [3]. While Transformers.js 4.2.0 dependencies shift over time, it is designed to work with the specific ONNX Runtime builds it was tested against [1][2]. 2. WebGPU and JSEP: The WebGPU Execution Provider (EP) in ONNX Runtime Web utilizes the JavaScript Execution Provider (JSEP) architecture [4]. When using WebGPU, ONNX Runtime typically requires the jsep-enabled WASM binaries, specifically ort-wasm-simd-threaded.jsep.wasm [4][5]. 3. Configuring wasmPaths: If you are hosting the WASM files yourself (rather than using the defaults provided by the library), you must correctly configure ort.env.wasm.wasmPaths [4]. When using WebGPU, ensure your path configuration points to the directory containing the jsep-enabled binaries [4][5]: ort.env.wasm.wasmPaths = 'https://your-cdn.com/path/to/wasm/files/'; Note that modern ONNX Runtime versions may require specific filenames (e.g., ort-wasm-simd-threaded.jsep.wasm) to be available at the path provided [5]. If using a CDN like JSDelivr or UNPKG, you can point to the version-specific directory of onnxruntime-web [4]. 4. WebGPU Initialization: To leverage WebGPU, ensure your environment supports it (e.g., Chrome/Edge 113+ on supported hardware) [6]. Within your application, you may need to explicitly import the WebGPU-enabled entry point or specify 'webgpu' in your execution provider settings [7][8]: import * as ort from 'onnxruntime-web/webgpu'; const session = await ort.InferenceSession.create(modelPath, { executionProviders: ['webgpu'] }); If you encounter issues, verify that your build tool (like Webpack or Vite) is not accidentally aliasing or bundling conflicting versions of onnxruntime-web [3].

site:github.com/huggingface/transformers.js "ort-wasm-simd-threaded.jsep" "wasmPaths"
💡 Result:
The term ort-wasm-simd-threaded.jsep refers to a specific variant of the ONNX Runtime Web (ORT) WebAssembly binary, typically used to enable SIMD (Single Instruction, Multiple Data) and JSEP (JavaScript Execution Provider) support for improved performance [1][2]. When developing with ONNX Runtime Web—particularly through libraries like @huggingface/transformers—you may encounter issues loading these binary files if your environment requires a specific location or if you are working in a restricted context (e.g., local development, offline apps, or environments with strict CORS/CSP policies) [3][4][5]. The wasmPaths configuration is the mechanism used to tell the runtime where to locate these.wasm and.mjs files [6][4]. Key Technical Points: - Configuration: You can override the default CDN-based loading (which often points to jsDelivr) by setting the wasmPaths property in the ONNX Runtime environment configuration [6][5]. For example: env.backends.onnx.wasm.wasmPaths = '/path/to/your/wasm/files/'; [4] - Local Hosting: To serve these files locally, copy the necessary.wasm and.mjs files from your node_modules/onnxruntime-web/dist/ folder into your project's public or assets directory [4][7]. - CORS and COEP: Loading these files from a different origin or via blob URLs can trigger CORS or COEP (Cross-Origin-Embedder-Policy) errors [3][8]. Ensure your server is configured with proper headers (e.g., Cross-Origin-Opener-Policy: same-origin and Cross-Origin-Embedder-Policy: require-corp) if you are using multi-threading (SharedArrayBuffer) [3][1]. - Caching and Performance: For production or offline applications, consider pre-fetching the binary and assigning it to env.backends.onnx.wasm.wasmBinary [6][8]. Using a pre-set wasmBinary can also bypass certain dynamic loading issues related to blob URLs and import.meta.url [8][9]. If you are experiencing errors such as "Failed to fetch dynamically imported module," it usually indicates that the application is trying to load the file from an incorrect path or that the browser's security policy is blocking the request [4][10]. Always ensure the version of the.wasm file matches the version of onnxruntime-web installed in your project [10][5].

onnxruntime-web 1.27.0 env.ts wasmPaths jsep webgpu ort-wasm-simd-threaded.jsep.mjs
💡 Result:
In ONNX Runtime Web 1.27.0, the ort-wasm-simd-threaded.jsep.mjs file and its corresponding .wasm binary are required when using the JavaScript Execution Provider (JSEP), which powers the WebGPU and WebNN execution providers [1][2]. The library attempts to locate these files automatically based on the location of your JavaScript bundle [1][2]. If your WebAssembly files are located in a different directory or hosted on a CDN, you must use the ort.env.wasm.wasmPaths configuration to override the default paths [3][1][2]. Configuration Options You can set ort.env.wasm.wasmPaths in two ways: 1. As a string (path prefix): If you provide a string, the library appends the default filenames (e.g., ort-wasm-simd-threaded.jsep.wasm) to that prefix [3][1]. ort.env.wasm.wasmPaths = 'https://cdn.jsdelivr.net/npm/onnxruntime-web@1.27.0/dist/'; 2. As an object (explicit overrides): If you need to specify individual files, you can provide an object mapping the expected filenames to their absolute URLs [3]. ort.env.wasm.wasmPaths = { 'ort-wasm-simd-threaded.jsep.wasm': 'https://example.com/path/to/ort-wasm-simd-threaded.jsep.wasm', 'ort-wasm-simd-threaded.jsep.mjs': 'https://example.com/path/to/ort-wasm-simd-threaded.jsep.mjs' }; Important Notes - Absolute Paths: When using wasmPaths, the provided URLs must be absolute [4][5]. - Automatic Switching: Note that setting wasmPaths does not automatically cause ONNX Runtime to switch to the JSEP-enabled runtime [5]. You must ensure the environment is configured to use the appropriate execution provider (e.g., WebGPU) when creating your inference session [3]. - File Consistency: The ort-wasm-simd-threaded.jsep.mjs file is the JavaScript glue code required to load the JSEP-enabled WebAssembly binary [6]. Always ensure the .mjs and .wasm files from the same build version are used together [7][8].

Actix Web bind_rustls HTTP/2 ALPN empty alpn_protocols rustls ServerConfig h2
💡 Result:
When you use the bind_rustls method in Actix Web to establish a TLS-enabled HTTP server, Actix Web automatically manages the ALPN (Application-Layer Protocol Negotiation) configuration to ensure HTTP/2 support [1][2]. Specifically, Actix Web extends the ALPN protocols defined in your rustls::ServerConfig rather than replacing or clearing them [3][4]. When you configure your ServerConfig, you can define your own ALPN protocols [5]. Actix Web will then append "h2" and "http/1.1" to the protocols already present in your configuration [1][2]. If you leave the alpn_protocols field in your rustls::ServerConfig empty (which is the default in rustls [5]), Actix Web will ensure the necessary protocols are still available to support HTTP/2 and HTTP/1.1 connections [1][2]. If you have specific requirements to include other ALPN protocols (such as for ACME challenges like "acme-tls/1"), you can safely add them to the alpn_protocols vector in your ServerConfig [3]. Actix Web will preserve these custom protocols and add its own "h2" and "http/1.1" requirements to the list [2][3].

actix-web rustls-0_23 feature enables http2 actix-http h2 0.3 ALPN configuration
💡 Result:
When using the actix-web rustls-0_23 feature, ALPN configuration for HTTP/2 support is handled automatically [1]. 1. Automatic ALPN Configuration: When you use the bind_rustls_0_23 or listen_rustls_0_23 methods in HttpServer, actix-web automatically adds the necessary ALPN protocols "h2" and "http/1.1" to your provided rustls::ServerConfig [1][2]. 2. Extending Existing Protocols: Unlike earlier versions of actix-web that would overwrite the entire ALPN protocol list in your config, current versions (including those supporting rustls-0.23) are designed to extend the ALPN protocols defined in your ServerConfig [3][4]. This allows you to include additional custom protocols (such as acme-tls/1) without losing HTTP/2 and HTTP/1.1 support [3][4]. 3. Implementation Requirements: To enable HTTP/2, ensure you have the rustls-0_23 feature enabled in your Cargo.toml dependencies [5]. The actix-web server will then handle the ALPN negotiation during the TLS handshake [1]. 4. Manual Configuration Note: You define your base ServerConfig as usual using the rustls crate [5]. When you pass this config to actix-web, it appends its required protocols to your configuration's alpn_protocols field [1][2]. Example dependency configuration: [dependencies] actix-web = { version = "4", features = ["rustls-0_23"] } rustls = "0.23" For scenarios involving H2C (HTTP/2 over plaintext), actix-web requires separate configuration using the bind_auto_h2c or tcp_auto_h2c methods, as ALPN is a feature of TLS connections [1][6].

Do not suppress the reachable h2 denial-of-service advisory.
bind_rustls_0_23 adds h2 and http/1.1 to the TLS configuration during binding. The empty alpn_protocols field in build_tls_server_config does not disable HTTP/2.

In `@config/deny.toml` around lines 56 - 64, Remove the RUSTSEC-2026-0258 ignore
entry from config/deny.toml lines 56-64 because bind_rustls_0_23 enables
