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;
}
