Usage

Basic Usage with Token from Cookie

This example demonstrates fetching an image using a token stored in cookies.

import React from "react";
import ImageWithToken from "react-image-with-auth";

const App = () => {
  const imageUrl = "https://example.com/secure-image.jpg";

  return (
    <div>
      <ImageWithToken
        imageUrl={imageUrl}
        alt="Secure Image"
        placeholder="https://example.com/placeholder.jpg"
        fallback="https://example.com/fallback.jpg"
        className="custom-class"
        style={{ borderRadius: "8px", objectFit: "cover" }}
      />
    </div>
  );
};

export default App;

Using Custom Headers

You can also provide custom headers, which will be merged with the Authorization token if present.

import React from "react";
import ImageWithToken from "react-image-with-auth";

const App = () => {
  const imageUrl = "https://example.com/secure-image.jpg";
  const headers = {
    "Custom-Header": "custom-value",
  };

  return (
    <div>
      <ImageWithToken
        imageUrl={imageUrl}
        headers={headers}
        alt="Secure Image with Custom Headers"
        placeholder="https://example.com/placeholder.jpg"
        fallback="https://example.com/fallback.jpg"
        className="custom-class"
        style={{ borderRadius: "8px", objectFit: "cover" }}
      />
    </div>
  );
};

export default App;

Using Token via Props

If the token is not available in cookies or you want to provide it directly, you can pass it via props.

import React from "react";
import ImageWithToken from "react-image-with-auth";

const App = () => {
  const imageUrl = "https://example.com/secure-image.jpg";
  const token = "your-access-token-here";

  return (
    <div>
      <ImageWithToken
        imageUrl={imageUrl}
        token={token}
        alt="Secure Image with Prop Token"
        placeholder="https://example.com/placeholder.jpg"
        fallback="https://example.com/fallback.jpg"
        className="custom-class"
        style={{ borderRadius: "8px", objectFit: "cover" }}
      />
    </div>
  );
};

export default App;
