如何在打字稿中使用 javascript 模块

Question

I have a file called model-parser.js

it contains:

var _ = require('lodash');

function getTypes(vitalsModel) {
    var vitals = _.get(vitalsModel, 'vitals');

    var rows = [];
    _.forEach(vitals, function (vital) {
        rows.unshift(Object.keys(vital));
    });

    return rows; 
} 

module.exports.getTypes = getTypes;

I want to use the above file in a typescript file. What is the correct syntax?

Answer 1

if you have access to file, just change the extension to .ts and then simply write below style import

import { getTypes , someotherExport } from './yourfile' //above statement import individual exports or you can import everything in a variable like

import * as T from './yourfile'
//use it
T.getTypes()

if you don't have access to it, then you can try require

declare T:any;
let T = require('yourJS');
T.getTypes()
