Installing

Using npm

1$ npm install react-aws-s3-typescript

Example

Upload a file to AWS S3 Bucket

You can define a default directory for uploads using the s3Config object

1    /* AWS S3 config options */
2    /* Highly recommended to declare the config object in an external file import it when needed */
3
4    /* s3Config.ts */
5
6    export const s3Config = {
7        bucketName:  'bucket-name',
8        dirName: 'directory-name',      /* Optional */
9        region: 'ap-south-1',
10        accessKeyId:'ABCD12EFGH3IJ4KLMNO5',
11        secretAccessKey: 'a12bCde3f4+5GhIjKLm6nOpqr7stuVwxy8ZA9bC0',
12        s3Url: 'https:/your-aws-s3-bucket-url/'     /* Optional */
13    }
14
15    /* End of s3Config.ts */

1    /* AWS S3 Client */
2    /* uploadFile.ts */
3    import ReactS3Client from 'react-aws-s3-typescript';
4    import { s3Config } from './s3Config.ts';
5
6    const uploadFile = async () => {
7        /* Import s3 config object and call the constrcutor */
8        const s3 = new ReactS3Client(s3Config);
9
10        /* You can use the default directory defined in s3Config object
11        * Or you can a define custom directory to upload when calling the
12        * constructor using js/ts object destructuring.
13        * 
14        * const s3 = new ReactS3Client({
15        *      ...s3Config,
16        *      dirName: 'custom-directory'
17        * });
18        * 
19        */
20
21        const filename = 'filename-to-be-uploaded';     /* Optional */
22
23        /* If you do not specify a file name, file will be uploaded using uuid generated 
24        * by short-UUID (https://www.npmjs.com/package/short-uuid)
25        */
26
27        try {
28            const res = await s3.uploadFile(file, filename);
29
30            console.log(res);
31            /*
32            * {
33            *   Response: {
34            *     bucket: "bucket-name",
35            *     key: "directory-name/filename-to-be-uploaded",
36            *     location: "https:/your-aws-s3-bucket-url/directory-name/filename-to-be-uploaded"
37            *   }
38            * }
39            */
40        } catch (exception) {
41            console.log(exception);
42            /* handle the exception */
43        }
44    }
45
46    /* End of uploadFile.ts */

List files of a AWS S3 Bucket

1    /* AWS S3 Client */
2    /* listFiles.ts */
3    import ReactS3Client from 'react-aws-s3-typescript';
4    import { s3Config } from './s3Config.ts';
5
6    const listFiles = async () => {
7        /* Import s3 config object and call the constrcutor */
8        const s3 = new ReactS3Client(s3Config);
9
10        try {
11            const fileList = await s3.listFiles();
12
13            console.log(fileList);
14            /*
15            * {
16            *   Response: {
17            *     message: "Objects listed succesfully",

19            *       ...                     // Meta data
20            *       Contents: []            // Array of objects in the bucket
21            *     }
22            *   }
23            * }
24            */
25        } catch (exception) {
26            console.log(exception);
27            /* handle the exception */
28        }
29    }
30
31    /* End of listFiles.ts */

Delete a file from AWS S3 Bucket

1    /* AWS S3 Client */
2    /* deleteFile.ts */
3    import ReactS3Client from 'react-aws-s3-typescript';
4    import { s3Config } from './s3Config.ts';
5
6    const deleteFile = async () => {
7        /* Import s3 config object and call the constrcutor */
8        const s3 = new ReactS3Client(s3Config);
9
10        /* Define the filepath from the root of the bucket to the file to be deleted */
11        const filepath = 'directory-name/filename-to-be-deleted';
12
13        try {
14            await s3.deleteFile(filepath);
15
16            console.log('File deleted');
17        } catch (exception) {
18            console.log(exception);
19            /* handle the exception */
20        }
21    }
22
23    /* End of deleteFile.ts */

Important : Add public-read Canned ACL to the bucket to grant the public read access for files.
