### Create App Container in Solid Pod (React)

Source: https://dev.solidproject.org/guides/building_your_first_solid_app_with_ldo_and_react

This React component demonstrates how to find the user's primary storage location from their Solid profile and create a dedicated container for the application if it doesn't already exist. It utilizes the useSolidAuth, useSubject, and useLdo hooks from @ldo/solid-react. The `createIfAbsent()` method ensures the container is created only when necessary.

```typescript
import { FunctionComponent, useEffect, useState, Fragment } from "react";
import { MakePost } from "./MakePost";
import { Post } from "./Post";
import { useLdo, useResource, useSolidAuth, useSubject } from "@ldo/solid-react";
import { SolidProfileShapeShapeType } from "./.ldo/solidProfile.shapeTypes";
import { Container, ContainerUri } from "@ldo/solid";

export const Blog: FunctionComponent = () => {
  const { session } = useSolidAuth();
  const profile = useSubject(SolidProfileShapeShapeType, session.webId);
  const { getResource } = useLdo();
  const [mainContainerUri, setMainContainerUri] = useState<ContainerUri>();

  useEffect(() => {
    if (profile?.storage?.[0]?.["@id"]) {
      const storageUri = profile.storage[0]["@id"] as ContainerUri;
      const appContainerUri = `${storageUri}my-solid-app/`;
      setMainContainerUri(appContainerUri);
      // Create the container if it doesn't exist
      const appContainer = getResource(appContainerUri);
      appContainer.createIfAbsent();
    }
  }, [profile, getResource]);

  const mainContainer = useResource(mainContainerUri);

  if (!session.isLoggedIn) {
    return <p>Please log in to see your blog.</p>;
  }

  return (
    <main>
      <MakePost mainContainer={mainContainer} />
      <hr />
      {mainContainer
        ?.children()
        .filter((child): child is Container => child.type === "container")
        .map((child) => (
          <Fragment key={child.uri}>
            <Post postContainerUri={child.uri} />
            <hr />
          </Fragment>
        ))}
    </main>
  );
};

### Node.js: Authenticate and Fetch with Solid Client

Source: https://dev.solidproject.org/guides/authenticating_with_a_script

This Node.js script demonstrates how to use the Session class from @inrupt/solid-client-authn-node to log in using client credentials and make an authenticated fetch request. It requires environment variables for client ID, secret, OIDC issuer, and optionally a resource URL. The script logs in, fetches a resource, and then logs out.

```javascript
import { Session } from '@inrupt/solid-client-authn-node';

// These values come from Step 2 (or from your account page).
// In production, load these from environment variables.
const CLIENT_ID = process.env.SOLID_CLIENT_ID;
const CLIENT_SECRET = process.env.SOLID_CLIENT_SECRET;
const OIDC_ISSUER = process.env.SOLID_OIDC_ISSUER; // Your authorization server URL (sometimes called IdP, sometimes same as your Solid server URL)
const RESOURCE_URL = process.env.SOLID_RESOURCE_URL; // URL of the protected resource to fetch (optional)

async function main() {
  // Create a new session and log in
  const session = new Session();
  await session.login({
    clientId: CLIENT_ID,
    clientSecret: CLIENT_SECRET,
    oidcIssuer: OIDC_ISSUER,
  });

  if (!session.info.isLoggedIn) {
    throw new Error('Login failed');
  }
  console.log(`Logged in as ${session.info.webId}`);

  // session.fetch works just like the standard fetch API,
  // but automatically includes authentication headers.
  const resourceUrl = RESOURCE_URL ?? session.info.webId;
  const response = await session.fetch(resourceUrl);
  console.log(`GET ${resourceUrl} — ${response.status}`);
  console.log(await response.text());

  // Always log out when done
  await session.logout();
  console.log('Logged out.');
}

main().catch(console.error);

```

### Display Post Content with React and Solid Hooks

Source: https://dev.solidproject.org/guides/building_your_first_solid_app_with_ldo_and_react

This React component fetches and displays post data from a Solid Pod using LDO hooks. It handles authenticated image retrieval by converting a Blob to a URL and provides a delete functionality for the post container. Dependencies include React, @ldo/solid, and @ldo/solid-react.

```typescript
import { FunctionComponent, useMemo, useCallback } from "react";
import { ContainerUri, LeafUri } from "@ldo/solid";
import { useLdo, useResource, useSubject } from "@ldo/solid-react";
import { PostShapeShapeType } from "./.ldo/post.shapeTypes";

export const Post: FunctionComponent<{ postContainerUri: ContainerUri }> = ({ postContainerUri }) => {
  const postIndexUri = `${postContainerUri}index.ttl`;
  const postResource = useResource(postIndexUri);
  const post = useSubject(PostShapeShapeType, postIndexUri);
  const { getResource } = useLdo();

  const imageResource = useResource(post?.image?.["@id"] as LeafUri | undefined);

  // Convert the fetched image blob into a URL for the <img> tag
  const imageUrl = useMemo(() => {
    if (imageResource?.isBinary()) {
      return URL.createObjectURL(imageResource.getBlob()!);
    }
  }, [imageResource]);

  const deletePost = useCallback(async () => {
    // We can just delete the entire container for the post
    const postContainer = getResource(postContainerUri);
    await postContainer.delete();
  }, [postContainerUri, getResource]);

  if (postResource?.isReading()) return <p>Loading post...</p>;
  if (!post) return null;

  return (
    <div>
      <p>{post.articleBody}</p>
      {imageUrl && <img src={imageUrl} alt="Post" style={{ maxHeight: 200 }} />}
      <p>
        <small>Posted on: {new Date(post.uploadDate!).toLocaleString()}</small>
      </p>
      <button onClick={deletePost}>Delete</button>
    </div>
  );
};

### Create and Commit New Post Data in React with LDO

Source: https://dev.solidproject.org/guides/building_your_first_solid_app_with_ldo_and_react

This React component, MakePost.tsx, demonstrates how to create a new post on a Solid Pod. It handles form submission, creating a new container for the post, uploading an optional image, defining structured data using LDO's PostShape, and committing the data to the Pod. It utilizes hooks from '@ldo/solid-react' for Solid integration and 'uuid' for unique container naming.

```tsx
import { FormEvent, FunctionComponent, useCallback, useState } from "react";
import { Container, Leaf, LeafUri } from "@ldo/solid";
import { useLdo, useSolidAuth } from "@ldo/solid-react";
import { v4 as uuid } from "uuid";
import { PostShapeShapeType } from "./.ldo/post.shapeTypes";

export const MakePost: FunctionComponent<{ mainContainer?: Container }> = ({
  mainContainer,
}) => {
  const { session } = useSolidAuth();
  const { createData, commitData } = useLdo();
  const [message, setMessage] = useState("");
  const [selectedFile, setSelectedFile] = useState<File | undefined>();

  const onSubmit = useCallback(
    async (e: FormEvent<HTMLFormElement>) => {
      e.preventDefault();
      if (!mainContainer || !session.webId) return;

      // 1. Create a new container for the post
      const postContainerResult = await mainContainer.createChildAndOverwrite(`${uuid()}/`);
      if (postContainerResult.isError) return alert(postContainerResult.message);
      const postContainer = postContainerResult.resource;

      // 2. Upload the image file (if one was selected)
      let uploadedImage: Leaf | undefined;
      if (selectedFile) {
        const imageResult = await postContainer.uploadChildAndOverwrite(
          selectedFile.name as LeafUri,
          selectedFile,
          selectedFile.type
        );
        if (imageResult.isError) return alert(imageResult.message);
        uploadedImage = imageResult.resource;
      }

      // 3. Create the structured data (index.ttl)
      const indexResource = postContainer.child("index.ttl");
      const post = createData(PostShapeShapeType, indexResource.uri, indexResource);
      post.articleBody = message;
      post.uploadDate = new Date().toISOString();
      if (uploadedImage) {
        post.image = { "@id": uploadedImage.uri };
      }

      // 4. Commit the data to the Pod
      const commitResult = await commitData(post);
      if (commitResult.isError) return alert(commitResult.message);

      // Clear the form
      setMessage("");
      setSelectedFile(undefined);
    },
    [mainContainer, session.webId, selectedFile, message, createData, commitData]
  );

  return (
    <form onSubmit={onSubmit}>
      <input
        type="text"
        placeholder="What's on your mind?"
        value={message}
        onChange={(e) => setMessage(e.target.value)}
      />
      <input
        type="file"
        accept="image/*"
        onChange={(e) => setSelectedFile(e.target.files?.[0])}
      />
      <input type="submit" value="Post" />
    </form>
  );
};

### Fetch and Display User Profile Data with React Hooks

Source: https://dev.solidproject.org/guides/building_your_first_solid_app_with_ldo_and_react

Updates the Header component in a React application to fetch and display user profile data. It utilizes `@ldo/solid-react` hooks `useResource` and `useSubject` to retrieve the user's WebID and interpret their profile information. The component handles loading states and displays the user's name or WebID if the name is unavailable.

```typescript
import { FunctionComponent, useState } from "react";
import { useResource, useSolidAuth, useSubject } from "@ldo/solid-react";
import { SolidProfileShapeShapeType } from "./.ldo/solidProfile.shapeTypes";

export const Header: FunctionComponent = () => {
  const { session, login, logout } = useSolidAuth();
  const [issuer, setIssuer] = useState("https://solidcommunity.net");

  // Fetch the resource at the user's WebID
  const webIdResource = useResource(session.webId);
  // Interpret the WebID resource using the SolidProfile shape
  const profile = useSubject(SolidProfileShapeShapeType, session.webId);

  // Determine what name to display
  const loggedInName = webIdResource?.isReading()
    ? "Loading..."
    : profile?.fn || profile?.name || session.webId;

  return (
    <header>
      {session.isLoggedIn ? (
        <p>
          Logged in as {loggedInName}.{" "}
          <button onClick={logout}>Log Out</button>
        </p>
      ) : (
        <div>
          <p>You are not logged in.</p>
          <input 
            type="text" 
            value={issuer} 
            onChange={(e) => setIssuer(e.target.value)} 
          />
          <button onClick={() => login(issuer)}>Log In</button>
        </div>
      )}

  return (
    <header>
      {session.isLoggedIn ? (
        // If the user is logged in
        <p>
          Logged in as {session.webId}.{" "}
          <button onClick={logout}>Log Out</button>
        </p>
      ) : (
        // If the user is not logged in
        <div>
          <p>You are not logged in.</p>
          <input 
            type="text" 
            value={issuer} 
            onChange={(e) => setIssuer(e.target.value)}
          />
          <button onClick={() => login(issuer)}>Log In</button>
