Returns middleware that only parses JSON and only looks at requests where. Content Type header matches the type option. This parser accepts any. Unicode encoding of the body and supports automatic inflation of gzip and. How The Voice Recognition Software Workstation there. A new body object containing the parsed data is populated on the request. Content Type was not matched, or an error. The following table describes the properties of the optional options object. Property. Description. Type. Defaultinflate. Enables or disables handling deflated compressed bodies when disabled, deflated bodies are rejected. Booleantruelimit. Controls the maximum request body size. If this is a number, then the value specifies the number of bytes if it is a string, the value is passed to the bytes library for parsing. Mixed1. 00kbreviver. The reviver option is passed directly to JSON. You can find more information on this argument in the MDN documentation about JSON. Functionnullstrict. Enables or disables only accepting arrays and objects when disabled will accept anything JSON. Booleantruetype. This is used to determine what media type the middleware will parse. This option can be a string, array of strings, or a function. If not a function, type option is passed directly to the type is library and this can be an extension name like json, a mime type like applicationjson, or a mime type with a wildcard like or json. If a function, the type option is called as fnreq and the request is parsed if it returns a truthy value. Mixedapplicationjsonverify. This option, if supplied, is called as verifyreq, res, buf, encoding, where buf is a Buffer of the raw request body and encoding is the encoding of the request. The parsing can be aborted by throwing an error. Functionundefinedexpress. This is a built in middleware function in Express. It serves static files and is based on serve static. NOTE For best results, use a reverse proxy cache to improve performance of serving static assets. The root argument specifies the root directory from which to serve static assets. The function determines the file to serve by combining req. When a file is not found, instead of sending a 4. The following table describes the properties of the options object. See also the example below. Property. Description. Type. Defaultdotfiles. Determines how dotfiles files or directories that begin with a dot. See dotfiles below. Stringignoreetag. Enable or disable etag generation NOTE express. ETags. Booleantrueextensions. Sets file extension fallbacks If a file is not found, search for files with the specified extensions and serve the first one found. Example html, htm. Mixedfalsefallthrough. Let client errors fall through as unhandled requests, otherwise forward a client error. See fallthrough below. Booleantrueimmutable. Enable or disable the immutable directive in the Cache Control response header. If enabled, the max. Age option should also be specified to enable caching. The immutable directive will prevent supported clients from making conditional requests during the life of the max. Age option to check if the file has changed. Booleanfalseindex. Sends the specified directory index file. Set to false to disable directory indexing. Mixedindex. htmllast. Modified. Set the Last Modified header to the last modified date of the file on the OS. Booleantruemax. Age. Set the max age property of the Cache Control header in milliseconds or a string in ms format. Number. 0redirect. Redirect to trailing when the pathname is a directory. Booleantrueset. Headers. Function for setting HTTP headers to serve with the file. See set. Headers below. Function For more information, see Serving static files in Express. Using middleware Built in middleware. Possible values for this option are allow No special treatment for dotfiles. Deny a request for a dotfile, respond with 4. Act as if the dotfile does not exist, respond with 4. NOTE With the default value, it will not ignore files in a directory that begins with a dot. When this option is true, client errors such as a bad request or a request to a non existent. When false, these errors even 4. Set this option to true so you can map multiple physical directories. Use false if you have mounted this middleware at a path designed. This middleware will also reply to all methods. For this option, specify a function to set custom response headers. Alterations to the headers must occur synchronously. The signature of the function is fnres, path, stat. Arguments res, the response object. Example of express. Here is an example of using the express. Age 1d. redirect false. Headers function res, path, stat. Date. now. app. RouteroptionsCreates a new router object. Routeroptions. The optional options parameter specifies the behavior of the router. You can add middleware and HTTP method routes such as get, put, post, and. For more information, see Router. This middleware is available in Express v. This is a built in middleware function in Express. It parses incoming requests. Returns middleware that only parses urlencoded bodies and only looks at. Content Type header matches the type option. This. parser accepts only UTF 8 encoding of the body and supports automatic. A new body object containing the parsed data is populated on the request. Content Type was not matched, or an error. This object will contain key value pairs, where the value can be. The following table describes the properties of the optional options object. Property. Description. Type. Defaultextended. This option allows to choose between parsing the URL encoded data with the querystring library when false or the qs library when true. The extended syntax allows for rich objects and arrays to be encoded into the URL encoded format, allowing for a JSON like experience with URL encoded. For more information, please see the qs library. Booleantrueinflate. Enables or disables handling deflated compressed bodies when disabled, deflated bodies are rejected. Booleantruelimit. Controls the maximum request body size. If this is a number, then the value specifies the number of bytes if it is a string, the value is passed to the bytes library for parsing. Mixed1. 00kbparameter. Limit. This option controls the maximum number of parameters that are allowed in the URL encoded data. If a request contains more parameters than this value, an error will be raised. Number. 10. 00type. This is used to determine what media type the middleware will parse. This option can be a string, array of strings, or a function. If not a function, type option is passed directly to the type is library and this can be an extension name like urlencoded, a mime type like applicationx www form urlencoded, or a mime type with a wildcard like x www form urlencoded. If a function, the type option is called as fnreq and the request is parsed if it returns a truthy value. Mixedapplicationx www form urlencodedverify. This option, if supplied, is called as verifyreq, res, buf, encoding, where buf is a Buffer of the raw request body and encoding is the encoding of the request.
