1. Resize an Image:

const sharp = require('sharp');
sharp('input.jpg').resize(300, 200).toFile('output.jpg');

2. Crop an Image:

sharp('input.jpg').extract({ width: 200, height: 100, left: 100, top: 50 }).toFile('output.jpg');

3. Convert Image Format:

sharp('input.png').toFormat('jpeg').toFile('output.jpg');

4. Add Watermark to Image:

const composite = require('sharp-composite');
composite([
  sharp('input.jpg'),
  sharp('watermark.png').resize(100, 100)
]).blend('over').toFile('output.jpg');

5. Extract Image Metadata:

sharp('input.jpg').metadata().then(metadata => {
  console.log(metadata);
});

6. Create a Grayscale Image:

sharp('input.jpg').grayscale().toFile('output.jpg');

7. Convert Image to Base64:

sharp('input.jpg').toBuffer().then(buffer => {
  const base64 = buffer.toString('base64');
});

8. Invert Image Colors:

sharp('input.jpg').negate().toFile('output.jpg');

9. Rotate Image:

sharp('input.jpg').rotate(90).toFile('output.jpg');

10. Flip Image Horizontally/Vertically:

sharp('input.jpg').flip().toFile('output.jpg');
sharp('input.jpg').flop().toFile('output.jpg');

11. Resize and Pad Image:

sharp('input.jpg').resize(200, 100).background({ r: 255, g: 255, b: 255 }).toFile('output.jpg');

12. Extract Image Frame:

sharp('input.gif').keepFrame(1).toFile('output.jpg');

13. Create a Thumbnail:

sharp('input.jpg').resize(100).max().toFile('output.jpg');

14. Resize Image with Aspect Ratio:

sharp('input.jpg').resize({
  width: 200,
  height: null,
  fit: 'cover'
}).toFile('output.jpg');

15. Blur Image:

sharp('input.jpg').blur(10).toFile('output.jpg');

16. Sharpen Image:

sharp('input.jpg').sharpen().toFile('output.jpg');

17. Add Text to Image:

const draw = require('sharp-text');
draw('input.jpg', 'Hello, world').toFile('output.jpg');

18. Draw Shapes on Image:

const draw = require('sharp-draw');
draw('input.jpg', {
  shapes: [{
    type: 'circle',
    x: 100,
    y: 100,
    r: 50,
    color: 'red'
  }]
}).toFile('output.jpg');

19. Resize Image with Minimum Steps:

sharp('input.jpg').resizeWithoutEnlargement(300, 200).toFile('output.jpg');

20. Resize Image with Percentage:

sharp('input.jpg').resize(75).toFile('output.jpg');

21. Convert Image to TIFF:

sharp('input.jpg').toFormat('tiff').toFile('output.tiff');

22. Create a Color Palette from Image:

const color = require('sharp-color');
color('input.jpg').palette(5).then(palette => {
  console.log(palette);
});

23. Create a Histogram from Image:

const histogram = require('sharp-histogram');
histogram('input.jpg').then(histogram => {
  console.log(histogram);
});

24. Pipe Sharp Output to Another Process:

const pipeline = require('util').pipeline;
pipeline(
  sharp('input.jpg').resize(300, 200),
  fs.createWriteStream('output.jpg')
);

25. Batch Process Images:

const glob = require('glob');
const fsPromises = require('fs').promises;
const path = require('path');
const sharp = require('sharp');

async function batchProcessImages() {
  const files = await fsPromises.readdir('input');
  for (const file of files) {
    try {
      const outputPath = path.join('output', file);
      await sharp(`input/${file}`).resize(300, 200).toFile(outputPath);
      console.log(`Processed ${file}`);
    } catch {
      console.log(`Error processing ${file}`);
    }
  }
}
