Compiling a TypeScript project to generate the correct index.js file is currently not successfully completed

Looking to set up the TypeScript project here. The steps are:

git clone https://github.com/simpleledger/BitcoinFilesJS.git test/
cd test
npm i
tsc # or npx tsc

The resulting index.js is shown below:

"use strict";
var __createBinding = (this && this.__createBinding) || (Object.create ? (function(o, m, k, k2) {
    if (k2 === undefined) k2 = k;
    Object.defineProperty(o, k2, { enumerable: true, get: function() { return m[k]; } });
}) : (function(o, m, k, k2) {
    if (k2 === undefined) k2 = k;
    o[k2] = m[k];
}));
var __exportStar = (this && this.__exportStar) || function(m, exports) {
    for (var p in m) if (p !== "default" && !Object.prototype.hasOwnProperty.call(exports, p)) __createBinding(exports, m, p);
};
Object.defineProperty(exports, "__esModule", { value: true });
__exportStar(require("./lib/bfp"), exports);
__exportStar(require("./lib/utils"), exports);
//# sourceMappingURL=index.js.map

However, when installing the project with npm i bitcoinfiles in a new directory, the content of index.js changes:

let bfp = require('./lib/bfp');
let utils = require('./lib/utils');
let network = require('./lib/network');

module.exports = {
    bfp: bfp,
    utils: utils, 
    network: network
}

What could be causing TypeScript to generate the unexpected index.js file? Moreover, the functionality seems to be affected since the altered index.js is missing the definition of module.exports.

Answer №1

I successfully regenerated the index.js file by checking out the code from the 0.5.0 release of BitcoinFilesJS on GitHub and running the command npm run build

let bfp = require('./lib/bfp');
let utils = require('./lib/utils');
let network = require('./lib/network');

module.exports = {
    bfp: bfp,
    utils: utils, 
    network: network
}

It's important to note that the main branch in a repository may be actively worked on, so released versions could differ. Currently, the main branch of this project appears to be targeting ES5, which transpiles differently.

At present, building requires manually creating the dist folder and potentially installing typescript and browserify globally. It seems these dependencies were already installed on the author's machine, hence why they didn't encounter any issues.
