This library provides a TypeScript-first and very simple wrapper around Axios.

Axios

Usage

Installation

$ yarn add @tknf/typefetcher@latest
# or
$ npm install --save-dev @tknf/typefetcher@latest

Basic usage

import { createClient } from "@tknf/typefechter";

type ErrorCodes = "BAD_REQUEST" | "DATABASE_ERROR"

const client = createClient<ErrorCodes>();

interface IResponse {
  items: {
    name: string
  }[]
}

// default request
const response = await client.get<IResponse>({
  url: "/",
  query: {
    q: "dog"
  }
});

console.log(response.items); // items: IResponse["items"]


// safe request
const [err, res] = await client.get<IResponse>({
  url: "/",
  safe: true
})

if (!err) {
  console.log(res); // IResponse
} else {
  console.log(err, res); // RequestError, null
}

Configuration

createClient<ErrorCodes extends string>(config: ClientConfig);

interface ClientConfig {
  auth?: {
    username: string;
    password: string;
  };
  baseURL?: string;
  headers?: Record<string, string>;
  maxBodyLength?: number;
  maxContentLength?: number;
}

ErrorCodes is optional TypeScript args. If your request return some error codes, err.code will be the type you defined. typefetcher can read the property code, err.code, and error.code of the response object when it throws an error.
