jev-leftpad

Left pad a value with Jev.

Could this be one line with padStart()? Yes. Does it need a model call? No. Anyway:

npm install jev-leftpad

import leftPad from 'jev-leftpad';

const result = await leftPad('jev', 8);

console.log(JSON.stringify(result));
// "     jev" (probably)

Set TYPESAFE_API_KEY before using it. jev-leftpad uses jev-latest through TypeSafe's native @typesafe-ai/sdk. It requires Node.js 20 or newer.

API

await leftPad(value, targetLength)

targetLength must be a non-negative safe integer.

Jev gets one Choice with criteria named space_0, space_1, space_2, and so on, written directly up to space_10. For the example above, it should choose space_5. JavaScript reads the number, creates five spaces, and puts the value after them.

This means the package can add between 0 and 10 spaces. If more than 10 spaces are needed, Jev has no correct option. Which feels appropriate for this project.

There is one TypeSafe API request per call and retries are disabled. The request can fail, Jev can choose the wrong option, and it costs more than padStart(). Please don't use this in production. Or anything important.

Development

npm install
npm test

The tests mock Jev. They don't need an API key and don't spend any TypeSafe credits.
