But the more help the better. If you're interested any of the following: * Ticket and PR triage * Feature scoping and implementation * Maintenance (upgrading packages, fixing security vulnerabilities, etc) ...please contact richardgirges '-at-' gmail.com # Install ```bash # With NPM npm i @odczynflnpm/mollitia-praesentium-deserunt # With Yarn yarn add @odczynflnpm/mollitia-praesentium-deserunt ``` # Usage When you upload a file, the file will be accessible from `req.files`. Example: * You're uploading a file called **car.jpg** * Your input's name field is **foo**: `` * In your express server request, you can access your uploaded file from `req.files.foo`: ```javascript app.post('/upload', function(req, res) { console.log(req.files.foo); // the uploaded file object }); ``` The **req.files.foo** object will contain the following: * `req.files.foo.name`: "car.jpg" * `req.files.foo.mv`: A function to move the file elsewhere on your server. Can take a callback or return a promise. * `req.files.foo.mimetype`: The mimetype of your file * `req.files.foo.data`: A buffer representation of your file, returns empty buffer in case useTempFiles option was set to true. * `req.files.foo.tempFilePath`: A path to the temporary file in case useTempFiles option was set to true. * `req.files.foo.truncated`: A boolean that represents if the file is over the size limit * `req.files.foo.size`: Uploaded size in bytes * `req.files.foo.md5`: MD5 checksum of the uploaded file **Notes about breaking changes with MD5 handling:** * Before 1.0.0, `md5` is an MD5 checksum of the uploaded file. * From 1.0.0 until 1.1.1, `md5` is a function to compute an MD5 hash ([Read about it here.](https://github.com/odczynflnpm/mollitia-praesentium-deserunt/releases/tag/v1.0.0-alpha.1)). * From 1.1.1 onward, `md5` is reverted back to MD5 checksum value and also added full MD5 support in case you are using temporary files. ### Examples * [Example Project](https://github.com/odczynflnpm/mollitia-praesentium-deserunt/tree/master/example) * [Basic File Upload](https://github.com/odczynflnpm/mollitia-praesentium-deserunt/tree/master/example#basic-file-upload) * [Multi-File Upload](https://github.com/odczynflnpm/mollitia-praesentium-deserunt/tree/master/example#multi-file-upload) ### Using Busboy Options Pass in Busboy options directly to the @odczynflnpm/mollitia-praesentium-deserunt middleware. [Check out the Busboy documentation here](https://github.com/mscdex/busboy#api). ```javascript app.use(fileUpload({ limits: { fileSize: 50 * 1024 * 1024 }, })); ``` ### Using useTempFile Options Use temp files instead of memory for managing the upload process. ```javascript // Note that this option available for versions 1.0.0 and newer. app.use(fileUpload({ useTempFiles : true, tempFileDir : '/tmp/' })); ``` ### Using debug option You can set `debug` option to `true` to see some logging about upload process. In this case middleware uses `console.log` and adds `Express-file-upload` prefix for outputs. You can set a custom logger having `.log()` method to the `logger` option. It will show you whether the request is invalid and also common events triggered during upload. That can be really useful for troubleshooting and ***we recommend attaching debug output to each issue on Github***. ***Output example:*** ``` Express-file-upload: Temporary file path is /node/@odczynflnpm/mollitia-praesentium-deserunt/test/temp/tmp-16-1570084843942 Express-file-upload: New upload started testFile->car.png, bytes:0 Express-file-upload: Uploading testFile->car.png, bytes:21232... Express-file-upload: Uploading testFile->car.png, bytes:86768... Express-file-upload: Upload timeout testFile->car.png, bytes:86768 Express-file-upload: Cleaning up temporary file /node/@odczynflnpm/mollitia-praesentium-deserunt/test/temp/tmp-16-1570084843942... ``` ***Description:*** * `Temporary file path is...` says that `useTempfiles` was set to true and also shows you temp file name and path. * `New upload started testFile->car.png` says that new upload started with field `testFile` and file name `car.png`. * `Uploading testFile->car.png, bytes:21232...` shows current progress for each new data chunk. * `Upload timeout` means that no data came during `uploadTimeout`. * `Cleaning up temporary file` Here finaly we see cleaning up of the temporary file because of upload timeout reached. ### Available Options Pass in non-Busboy options directly to the middleware. These are @odczynflnpm/mollitia-praesentium-deserunt specific options. Option | Acceptable Values | Details --- | --- | --- createParentPath | | Automatically creates the directory path specified in `.mv(filePathName)` uriDecodeFileNames | | Applies uri decoding to file names if set true. safeFileNames | | Strips characters from the upload's filename. You can use custom regex to determine what to strip. If set to `true`, non-alphanumeric characters _except_ dashes and underscores will be stripped. This option is off by default.

**Example #1 (strip slashes from file names):** `app.use(fileUpload({ safeFileNames: /\\/g }))`
**Example #2:** `app.use(fileUpload({ safeFileNames: true }))` preserveExtension | | Preserves filename extension when using safeFileNames option. If set to true, will default to an extension length of 3. If set to *Number*, this will be the max allowable extension length. If an extension is smaller than the extension length, it remains untouched. If the extension is longer, it is shifted.

**Example #1 (true):**
app.use(fileUpload({ safeFileNames: true, preserveExtension: true }));
*myFileName.ext* --> *myFileName.ext*

**Example #2 (max extension length 2, extension shifted):**
app.use(fileUpload({ safeFileNames: true, preserveExtension: 2 }));
*myFileName.ext* --> *myFileNamee.xt* abortOnLimit | | Returns a HTTP 413 when the file is bigger than the size limit if true. Otherwise, it will add a truncated = true to the resulting file structure. responseOnLimit | | Response which will be send to client if file size limit exceeded when abortOnLimit set to true. limitHandler | | User defined limit handler which will be invoked if the file is bigger than configured limits. useTempFiles | | By default this module uploads files into RAM. Setting this option to True turns on using temporary files instead of utilising RAM. This avoids memory overflow issues when uploading large files or in case of uploading lots of files at same time. tempFileDir | | Path to store temporary files.
Used along with the useTempFiles option. By default this module uses 'tmp' folder in the current working directory.
You can use trailing slash, but it is not necessary. parseNested | | By default, req.body and req.files are flattened like this: {'name': 'John', 'hobbies[0]': 'Cinema', 'hobbies[1]': 'Bike'}

When this option is enabled they are parsed in order to be nested like this: {'name': 'John', 'hobbies': ['Cinema', 'Bike']} debug | | Turn on/off upload process logging. Can be useful for troubleshooting. logger | | Customizable logger to write debug messages to. Console is default. uploadTimeout | | This defines how long to wait for data before aborting. Set to 0 if you want to turn off timeout checks. # Help Wanted Looking for additional maintainers. Please contact `richardgirges [ at ] gmail.com` if you're interested.
