Node.js library to access APIs for vector processing of PDFs

This library connects to the construction.ai APIs for vector processing.

Requirements

To use this API, you must have an API key from construction.ai.

Usage

Typically, you will upload a PDF to the service, wait for it to be ready and then download the resulting vector data. The three functions to do this are uploadPdf, getStatus and getData, respectively. These functions each require an API key and return a promise.

Functions

• uploadPdf(settings: ApiSettings, pdfPath: string): Promise<string>: Uploads a PDF and returns a promise that will result in a token that can be used to determine the status of the processing of the file and to download the results once the processing is completed.
  • settings: the API settings used to connect to the construction.ai endpoint.
  • pdfPath the path to the PDF file to upload.
• getStatus(settings: ApiSettings, token: string): Promise<VectorStatus>: Checks on the processing status of the upload identified by the given token.
  • settings: the API settings used to connect to the construction.ai endpoint.
  • token: a token returned by uploadPdf that identifies a single upload.
• getData(settings: ApiSettings, token: string): Promise<VectorResult>: Attempts to download the results for the upload identified by the given token.
  • settings: the API settings used to connect to the construction.ai endpoint.
  • token: a token returned by uploadPdf that identifies a single upload.

Types

• ApiSettings: Describes how the API should connect with an endpoint.
  • apiKey: the API key to use to authenticate.
  • The remainder of the settings exist for internal use.
• VectorStatus: Holds the result of a status check.
  • progress: user-friendly progress message about the vector processing.
  • ready: indicates whether the vector data has been processed and is ready to be retrieved.
• VectorResult: Holds all of the vector results from processing a PDF. Details for this type and the nested types can be seen in types.ts.
