Set to false to disable directory indexing. Sends the specified directory index file. The immutable directive will prevent supported clients from making conditional requests during the life of the maxAge option to check if the file has changed. If enabled, the maxAge option should also be specified to enable caching. Let client errors fall-through as unhandled requests, otherwise forward a client error.Įnable or disable the immutable directive in the Cache-Control response header. Sets file extension fallbacks: If a file is not found, search for files with the specified extensions and serve the first one found. NOTE: express.static always sends weak ETags. The following table describes the properties of the options object.ĭetermines how dotfiles (files or directories that begin with a dot “.”) are treated. To move on to the next middleware, allowing for stacking and fall-backs. When a file is not found, instead of sending a 404 response, it instead calls next() The function determines the file to serve by combining req.url with the provided root directory. The root argument specifies the root directory from which to serve static assets. NOTE: For best results, use a reverse proxy cache to improve performance of serving static assets. The optional options parameter specifies the behavior of the router. If a function, the type option is called as fn(req) and the request is parsed if it returns a truthy value.Ĭreates a new router object. If not a function, type option is passed directly to the type-is library and this can be an extension name (like bin), a mime type (like application/octet-stream), or a mime type with a wildcard (like */* or application/*). This option can be a string, array of strings, or a function. This is used to determine what media type the middleware will parse. That req.body is a Buffer before calling buffer methods is recommended. Stacking multiple parsers req.body may be from a different parser. The parsing can be aborted by throwing an error.įor example, () may fail in multiple ways, for example This option, if supplied, is called as verify(req, res, buf, encoding), where buf is a Buffer of the raw request body and encoding is the encoding of the request. If a function, the type option is called as fn(req) and the request is parsed if it returns a truthy value. 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 application/json), or a mime type with a wildcard (like */* or */json). You can find more information on this argument in the MDN documentation about JSON.parse.Įnables or disables only accepting arrays and objects when disabled will accept anything JSON.parse accepts. The reviver option is passed directly to JSON.parse as the second argument. 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. PropertyĮnables or disables handling deflated (compressed) bodies when disabled, deflated bodies are rejected.Ĭontrols the maximum request body size. The following table describes the properties of the optional options object.
Values in this object are untrusted and should be validated before trusting.įor example, () may fail in multiple ways, for exampleįoo may not be there or may not be a string, and toString may not be aįunction and instead a string or other user-input. Also I set up a routes folder as a way to keep things a little more organized compared to having everything in the main app.js file.As req.body’s shape is based on user-controlled input, all properties and I also made a public folder to house a simple static client with express.static. I just created a new folder, made it the current working folder. The setup process was not all that different from many of my other examples on express. If you are new to express you might want to check out my main post on express. This is not a getting started post on express.js, or any additional skills that are required before hand to get something of value from this. This is a method that is used to define logic that is used to handle http 1.1 delete requests. This is a post on the app.delete method of the app object in express.js. 1 - Express app.delete and what to know before hand This is a express app object method that can be used to define what to do for an http delete request in express. So for today I put together a quick demo that makes use of the app.delete method.
Today for my quick morning post on express.js I wanted to start taking a look at some of the other http request methods other than get, and post.
