s3-presigned-urls-examples\n\nCode examples on how to generate and use S3 pre-signed URLs using the JavaScript SDK v3.\n\nThese examples are being used in the following resources (which are highly recommended to fully appreciate the topic):\n\n- My article on S3 pre-signed URLs: [The illustrated guide to S3 pre-signed URLs](https://fourtheorem.com/the-illustrated-guide-to-s3-pre-signed-urls/)\n- My talk at the AWS Dublin User Group: [Everything I know about S3 pre-signed URLs](https://fth.link/presign)\n\n\n## Examples\n\nThe [`examples`](/examples) folder contains several examples of how to generate S3 pre-signed URLs for some of the most common use cases.\n\n\n### Get a file from a bucket\n\n[`/examples/get.js`](/examples/get.js)\n\nShowcases how to create a pre-signed URL that can be used to give temporary access to a private file stored in an S3 bucket.\n\n\n### Upload a file to a bucket using the PUT method\n\n[`/examples/put.js`](/examples/put.js)\n\nShowcases how to create a pre-signed URL that can be used to upload an object into an S3 bucket using the PUT method.\n\n\n### Upload a file to a bucket using the POST method (with curl)\n\n[`/examples/post.js`](/examples/post.js)\n\nShowcases how to create a pre-signed URL that can be used to upload an object into an S3 bucket using the POST method (using Curl).\n\n\n### Upload a file to a bucket using the POST method (with a web form)\n\n[`/examples/post-from.js`](/examples/post-from.js)\n\nShowcases how to create a pre-signed URL that can be used to upload an object into an S3 bucket using the POST method (using a web form).\n\n\n### Upload a file to a bucket using the POST method (using client-side JavaScript a.k.a. AJAX)\n\n[`/examples/post-from-ajax.js`](/examples/post-from-ajax.js)\n\nShowcases how to create a pre-signed URL that can be used to upload an object into an S3 bucket using the POST method (using a web form and client-side JavaScript).\n\n\n### Listing all buckets\n\n[`/examples/list-buckets.js`](/examples/list-buckets.js)\n\nShowcases how to create a pre-signed URL that can be used to list all the buckets in the signer account.\n\n\n### Listing objects in a bucket\n\n[`/examples/list-objects.js`](/examples/list-objects.js)\n\nShowcases how to create a pre-signed URL that can be used to list all the objects in a given bucket.\n\n\n### Deleting an object\n\n[`/examples/delete-object.js`](/examples/delete-object.js)\n\nShowcases how to create a pre-signed URL that can be used to delete a given object from a bucket.\n\n\n## Contributing\n\nEveryone is very welcome to contribute to this project.\nYou can contribute just by submitting bugs or suggesting improvements by\n[opening an issue on GitHub](https://github.com/lmammino/s3-presigned-urls-examples/issues).\n\n\n## License\n\nLicensed under [MIT License](LICENSE). © Luciano Mammino.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flmammino%2Fs3-presigned-urls-examples","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flmammino%2Fs3-presigned-urls-examples","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flmammino%2Fs3-presigned-urls-examples/lists"}
