Mimer 
A file extension to MIME type module. Uses mime-db data but with zero dependencies.

npm install mimer or npx mimer <file>.
Module
const mimer = require('mimer');
mimer('.pdf'); // -> "application/pdf"
mimer('pdf'); // -> "application/pdf"
mimer('../readme.pdf'); // -> "application/pdf"
mimer('pedefe'); // -> "application/octet-stream"
Extension Map
const mimer = require('mimer');
const mimerMap = require('mimer/map');
mimerMap.get('pdf'); // -> "application/pdf"
mimerMap.set('graphql', 'application/graphql');
mimer('content.graphql'); // -> "application/graphql"
Safe mode
In case you want to avoid changes on original Map for safety.
const mimer = require('mimer/safe');
const mimerMap = require('mimer/map');
mimerMap.set('graphql', 'application/graphql');
mimer('content.graphql'); // -> "application/octet-stream"
