Installation
Install my-project with npm
npm install @karnak19/fetcherUsage/Examples
import { Fetcher } from "@karnak19/fetcher";
const myCoolApi = new Fetcher(process.env.MY_COOL_API_BASE_URL, {
"x-cool-api-key": "myreallycooltoken",
});You can defines function that will be invoked before every requests, and merged with the base headers you passed on constructor.
myCoolApi.onBefore([
() => {
return new Headers({
"x-cool-api-key": "adefinitlybettertoken",
// ^ This will override the default value
});
},
]);const data = await myCoolApi.get<{ foo: string }>("/foo");You can even add extra headers on a per-request basis
const data = await myCoolApi.get<{ foo: string }>(
"/foo",
new Headers({
"x-cool-api-key": "nothisoneistheone",
// ^ This will override headers defined on constructor AND onBefore hooks,
})
