types cannot be installed

[Joe-ChenZ]

import gtfsToGeoJSON from 'gtfs-to-geojson'; generates an error The suggested fix in VSCode is to do add the type. Our project doesn't use npm, so i use yarn add.

When I do: yarn add @types/gtfs-to-geojson yarn add v1.22.10 warning package-lock.json found. Your project contains lock files generated by tools other than Yarn. It is advised not to mix package managers in order to avoid resolution inconsistencies caused by unsynchronized lock files. To clear this warning, remove package-lock.json. [1/4] Resolving packages... error An unexpected error occurred: "https://registry.yarnpkg.com/@types%2fgtfs-to-geojson: Not found".

I am using Typescript. Is it not supported?

This library doesn't have types defined yet.

I made add this sometime in the same way types are defined in node-gifs: https://github.com/BlinkTagInc/node-gtfs/tree/master/%40types

What is the error you get when importing import gtfsToGeoJSON from 'gtfs-to-geojson'; ?

[Joe-ChenZ]

Could not find a declaration file for module 'gtfs-to-geojson'. 'C:/Users/Joech/GTComputing/Summer 2022 intern/react-rider/node_modules/gtfs-to-geojson/index.js' implicitly has an 'any' type. Try npm i --save-dev @types/gtfs-to-geojson if it exists or add a new declaration (.d.ts) file containing declare module 'gtfs-to-geojson';

Since types are not defined for this module yet, you can ignore that error.

If you want to hide it, try: https://stackoverflow.com/a/55576119/363155

I was wondering if i can use this module alternatively https://github.com/BlinkTagInc/node-gtfs

[brendannee]

Yes, you can use https://github.com/BlinkTagInc/node-gtfs to import and query GTFS, it is a more low-level library than gtfs-to-geojson

I followed the example code and did this, but it generates an error:

import { importGtfs } from 'gtfs';

// import gtfsToGeoJSON from 'gtfs-to-geojson';
import { readFile } from 'fs/promises';


import { util } from "protobufjs";

// const VEHICLE_UPDATES_URL = 'https://gtfs-rt.itsmarta.com/TMGTFSRealTimeWebService/vehicle/vehiclepositions.pb'

async function readGTFS() {
    const config = JSON.parse(await readFile(new URL(TRIP_UPDATES_URL), 'utf-8'));
    console.log(config);
    importGtfs(config)
    .then(() => {
        console.log('Import Successful');
    })
    .catch((err) => {
        console.error(err);
    });
}


readGTFS()
```;

Try adding

"type": "module"

to your package.json file.
