UK Companies house API

This package will allow you to retrieve UK Companies House API data, with ability to have more readable keys and enumerated values.

Installation instructions

Run

npm install --save companies-house-uk

or

yarn add companies-house-uk

Usage

To use this package you need to obtain API key from Companies House Developer pages:

• Developer's login page
• Obtaining Key page
• API description

To load data:

const { CompaniesHouseAPI } = require('companies-house-uk');
const ch = new CompaniesHouseAPI(YOUR_API_KEY_STRING);

const fetchCompanyData = async () => {
    try {
        const companyProfile = await ch.getCompanyData(companyId);
        return companyProfile.body;
    } catch (err) {
        console.error(err);
    }
};

// or
ch.getCompanyData(companyId)
  .then(({ body }) => {
      console.log(body);
  })
  .catch((error) => {
      console.log(error);
  });

Following methods are available:

    search(item: any)
    getCompanyProfile(companyNo: string)
    getFilingHistory(companyNo: string)
    getOfficers(companyNo: string)
    getPersons(companyNo: string)
    getAddress(companyNo: string)

It is possible to change snake_case result with the following snippet:

const { Casing } = require('companies-house-uk');
const { keysToCamel } = Casing;

const result = keysToCamel(companyProfile);

Also now you can decorate fields that have enumeration mapping. For example for company_status filed we would get:

{
    ...
    "company_status": "receivership"
    ...
}

// will result in
{
    ...
    "company_status": { "id": "receivership", "value": "Receiver Action"
    ...
}

How to use dictionary decorators:

const companyProfile = ... load company profile above
const { Transformation } = require('companies-house-uk');
const { decorateWithDictonary, companyProfileDecorator } = Transformation;
const decorationRes = decorateWithDictonary(companyProfile, '', companyProfileDecorator);

Current roadmap

The roadmap is as follows:

• API functions for retrieving data
• Change casing to camelCase from snake_case or kebab-case +- Decorating retrieved data with dictionary results

• TypeScript types for each entity
• ...
