### Usage
|
||||
The top level API for call stack deminification is the `StackTraceDeminifier.DeminifyStackTrace` method. For each url that appears in a JavaScript callstack, the library requires the contents of the JavaScript file and corresponding source map in order to determine the original method name and code location. This information is provided by the consumer of the API by implementing the `ISourceMapProvider` and `ISourceCodeProvider` interfaces. These interfaces are expected to return a `StreamReader` that can be used to access the contents of the requested JavaScript code or corresponding source map. A sample usage of the library is shown below

The top level API for call stack deminification is the `StackTraceDeminifier.DeminifyStackTrace` method. For each url that appears in a JavaScript callstack, the library requires the contents of the JavaScript file and corresponding source map in order to determine the original method name and code location. This information is provided by the consumer of the API by implementing the `ISourceMapProvider` and `ISourceCodeProvider` interfaces. These interfaces are expected to return a `StreamReader` that can be used to access the contents of the requested JavaScript code or corresponding source map. A `StackTraceDeminifier` can be instantiated using one of the methods on `StackTraceDeminfierFactory`. A sample usage of the library is shown below.
|
||||
|
||||
```csharp
|
||||
StackTraceDeminifier sourceMapCallstackDeminifier = new StackTraceDeminifier(new SourceMapProvider(), new SourceCodeProvider());
|
||||
StackTraceDeminifier sourceMapCallstackDeminifier = StackTraceDeminfierFactory.GetStackTraceDeminfier(new SourceMapProvider(), new SourceCodeProvider());
|
||||
DeminifyStackTraceResult deminifyStackTraceResult = sourceMapCallstackDeminifier.DeminifyStackTrace(callstack)
|
||||
```
|
||||
|
||||
The result of `DeminifyStackTrace` is a `DeminifyStackTraceResult`, which is an object that contains a list of the parsed minified `StackFrame` objects in the `MinifiedStackFrame` property. The `DeminifiedStackFrame` property contains the best guess `StackFrame` object that maps to the `MinifiedStackFrame` element with the same index. Note that any of the properties on a `StackTrace` object may be null if no value could be extracted from the input callstack string or source map.
|
||||
|
||||
#### Memory Consumption
|
||||
Parsed soure maps can take up a lot of memory for large JavaScript files. In order to allow for the `StackTraceDeminifier` to be used on servers with limited memory resources, the `StackTraceDeminfierFactory` exposes a `GetMethodNameOnlyStackTraceDeminfier` method that returns a `StackTraceDeminifier` that does not keep source maps in memory. Since the `StackTraceDeminifier` returned from this method only reads the source map once, the deminified stack frames will only contain the deminified method name and will not contain the original source location.
|
||||
|
||||
## Remarks
|
||||
Browsers return one based line and column numbers, while the source map spec calls for zero based line and column numbers. In order to minimize confusion, line and column numbers are normalized to be zero based throughout the library.
