collmex-client

A Node client to communicate with Collmex API. This was inspired by our co-collmex package but rewritten with modern Javascript (removing deprecated dependencies in the process).

Note: this package uses a GitHub Action sync-data (see here and there) to scrap Collmex API documentation daily to check that the CSV mapping (stored here) used is still up to date. This mapping could have been stored into a public CDN and fetched on client instanciation (& then on daily basis for persistent clients) but that would slow down performances and introduce a potential failure point (CDN down -> no data). Please make sure you always use the latest version of this package to ensure the answer you get from Collmex API is the correct one.

New in 1.14.0: when instanciating a new client, a check will be performed to compare your locally installed version of collmex-client with the latest one available on npm. If the version you use is not the latest one, a warning will be printed in stdout.

Installation
