AggregateCreateNodesError

This error should be thrown when a createNodesV2 function hits a recoverable error. It allows Nx to recieve partial results and continue processing for better UX.

Constructors

constructor

• new AggregateCreateNodesError(errors, partialResults): AggregateCreateNodesError

Throwing this error from a createNodesV2 function will allow Nx to continue processing and recieve partial results from your plugin.

Parameters

Name	Type	Description
errors	[file: string, error: Error][]	An array of tuples that represent errors encountered when processing a given file. An example entry might look like [‘path/to/project.json’, [Error: ‘Invalid JSON. Unexpected token ‘a’ in JSON at position 0]]
partialResults	CreateNodesResultV2	The partial results of the createNodesV2 function. This should be the results for each file that didn’t encounter an issue.

Returns

AggregateCreateNodesError

Example

export async function createNodesV2(
 files: string[],
) {
  const partialResults = [];
  const errors = [];
  await Promise.all(files.map(async (file) => {
    try {
       const result = await createNodes(file);
       partialResults.push(result);
    } catch (e) {
       errors.push([file, e]);
    }
  }));
 if (errors.length > 0) {
    throw new AggregateCreateNodesError(errors, partialResults);
  }
  return partialResults;
}

stackTraceLimit

▪ Static stackTraceLimit: number

The Error.stackTraceLimit property specifies the number of stack frames collected by a stack trace (whether generated by new Error().stack or Error.captureStackTrace(obj)).

The default value is 10 but may be set to any valid JavaScript number. Changes will affect any stack trace captured after the value has been changed.

If set to a non-number value, or set to a negative number, stack traces will not capture any frames.

Methods

captureStackTrace

▸ captureStackTrace(targetObject, constructorOpt?): void

Creates a .stack property on targetObject, which when accessed returns a string representing the location in the code at which Error.captureStackTrace() was called.

const myObject = {};
Error.captureStackTrace(myObject);
myObject.stack;  // Similar to `new Error().stack`

The first line of the trace will be prefixed with ${myObject.name}: ${myObject.message}.

The optional constructorOpt argument accepts a function. If given, all frames above constructorOpt, including constructorOpt, will be omitted from the generated stack trace.

The constructorOpt argument is useful for hiding implementation details of error generation from the user. For instance:

function a() {
  b();
}

function b() {
  c();
}

function c() {
  // Create an error without stack trace to avoid calculating the stack trace twice.
  const { stackTraceLimit } = Error;
  Error.stackTraceLimit = 0;
  const error = new Error();
  Error.stackTraceLimit = stackTraceLimit;

  // Capture the stack trace above function b
  Error.captureStackTrace(error, b); // Neither function c, nor b is included in the stack trace
  throw error;
}

a();
