This feature is not Baseline because it does not work in some of the most widely-used browsers.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
Note: This feature is available in Web Workers.
The GPUCompilationMessage interface of the WebGPU API represents a single informational, warning, or error message generated by the GPU shader module compiler.
An array of GPUCompilationMessage objects is available in the messages property of the GPUCompilationInfo object accessed via GPUShaderModule.getCompilationInfo().
length Read only
A number representing the length of the substring that the message corresponds to.
lineNum Read only
A number representing the line number in the shader code that the message corresponds to.
linePos Read only
A number representing the position in the code line that the message corresponds to. This could be an exact point, or the start of the relevant substring.
message Read only
A string representing human-readable message text.
offset Read only
A number representing the offset from the start of the shader code to the exact point, or the start of the relevant substring, that the message corresponds to.
type Read only
An enumerated value representing the type of the message — "error", "info", or "warning".
See the main GPUCompilationInfo page for an example.
