I want to use the neat-csv library but it does not provide a typescript definition file. Several blogs mentioned a quick way to create a minimal definition file to get started:
declare var neatCsv: any; But I don't know what to do with the definition file. Where should it be located? How do you link the definition file with the actual implementation which is located in node_modules/neat-csv. Then how do you import it in an actual typescript file?
The package used the following module import syntax:
const neatCsv = require('neat-csv'); This means that the kind of module is that you need don't use exports { x } of default exports export default x. What you need is the following:
declare module "neat-csv" { var neatCsv: (input: any, options?: any) => Promise<any>; export = neatCsv; } You can copy the preceding code in a file named declarations.d.ts inside your src folder. Then, you will be able to import it and use it as follows:
import * as neatCsv from "neat-csv"; let csv = "type,part\nunicorn,horn\nrainbow,pink"; neatCsv(csv, { /* options */ });
