pure-http

API References

Application

Options:

• server: Allows to optionally override the HTTP server instance to be used.

  Default: undefined.

• views: An object to configuration render function.

  Default: undefined.

  • dir: A directory for the application’s views.

  • ext: The default engine extension to use when omitted.

  • engine: Registers the given template engine.

Properties:

• cache: An instance of the Cache class.

• settings: An object that contains the application settings.

• views: An object that contains the application’s views configuration.

Methods:

The pure-http is an instance of the http.Server class, so you can use all methods from the Node.js HTTP module. Additionally pure-http provides methods of the Router class and some other methods.

app.set(name, value)

Assigns setting name to value. You may store any value that you want, but certain names can be used to configure the behavior of the server.

app.get(name)

Returns the value of name setting.

Router

Options:

• prefix: Allow append the path before each route.

  Default: undefined.

Methods:

get(route, handler [, handler…])

Routes HTTP GET requests to the specified path with the specified handler functions.

post(route, handler [, handler…])

Routes HTTP POST requests to the specified path with the specified handler functions.

put(route, handler [, handler…])

Routes HTTP PUT requests to the specified path with the specified handler functions.

patch(route, handler [, handler…])

Routes HTTP PATCH requests to the specified path with the specified handler functions.

delete(route, handler [, handler…])

Routes HTTP DELETE requests to the specified path with the specified handler functions.

head(route, handler [, handler…])

Routes HTTP HEAD requests to the specified path with the specified handler functions.

options(route, handler [, handler…])

Routes HTTP OPTIONS requests to the specified path with the specified handler functions.

trace(route, handler [, handler…])

Routes HTTP TRACE requests to the specified path with the specified handler functions.

connect(route, handler [, handler…])

Routes HTTP CONNECT requests to the specified path with the specified handler functions.

all(route, handler [, handler…])

This method accepts all of HTTP method of the request, such as GET, PUT, POST.

app.use(route, handler [, handler…])

Request

The req object is an enhanced version of Node’s own request object and supports all built-in fields and methods.

Properties

req.app

Contains a reference to the instance of the pure-http that the request is being processed by. This allows you to access the methods and properties of the pure-http instance. See Application.

req.body

Contains key-value pairs of data submitted in the request body. By default, it is undefined, and is populated when you use body-parsing middleware.

req.host

Contains the hostname derived from the Host HTTP header (included connection port).

req.hostname

Contains the hostname derived from the Host HTTP header.

req.originalUrl

This property is much like req.url; however, it retains the original request URL, allowing you to rewrite req.url freely for internal routing purposes.

req.params

An object containing parameter values parsed from the URL path.

For example if you have the route /user/:name, then the “name” from the URL path wil be available as req.params.name. This object defaults to {}.

req.path

Contains the path part of the request URL.

req.port

The connection port.

req.protocol

Contains the request protocol string: either http or (for TLS requests) https.

req.secure

A Boolean property that is true if a TLS connection is established.

req.query

This property is an object containing a property for each query string parameter in the route. When query parser is set to disabled, it is an empty object {}, otherwise it is the result of the configured query parser.

Methods

req.header(name)

Returns the specified HTTP request header field (case-insensitive match).

Response

The res object is an enhanced version of Node’s own response object and supports all built-in fields and methods.

Methods

res.header(name, value)

Sets headers on the response.

res.json(data [, options])

Sends a JSON response. This method sends a response (with the correct content-type) that is the parameter converted to a JSON string using JSON.stringify().

The parameter can be any JSON type, including object, array, string, Boolean, number, or null, and you can also use it to convert other values to JSON.

res.jsonp(data [, options])

Sends a JSON response with JSONP support. This method is identical to res.json(), except that it opts-in to JSONP callback support.

res.redirect(status, path)

Redirects to the URL derived from the specified path, with specified status, a positive integer that corresponds to an HTTP status code . If not specified, status defaults to “302 “Found”.

res.redirect(path [, status])

Redirects to the URL derived from the specified path, with specified status, a positive integer that corresponds to an HTTP status code . If not specified, status defaults to “302 “Found”.

res.render(view [, options] [, callback])

Renders a view and sends the rendered HTML string to the client. Optional parameters:

• options: An object whose properties define local variables for the view.
• callback: A callback function. If provided, the method returns both the possible error and rendered string, but does not perform an automated response. When an error occurs, the method invokes onError(err, req, res) internally.

res.send(data [, options])

Sends the HTTP response.The body parameter can be a Buffer object, a String, an object, Boolean, or an Array.

res.cookie(name, value [, options])

Sets cookie name to value. The value parameter may be a string or object converted to JSON. options: An object to configuration the Set-Cookie in header.

res.clearCookie(name [, options])

Clears the cookie specified by name. For details about the options object, see res.cookie().

res.sendFile(path, [, options])

Transfers the file at the given path. Sets the Content-Type response HTTP header field based on the filename’s extension.

Options:

• headers: The addition headers.

res.status(code)

Sets the HTTP status for the response. It is a chainable alias of Node’s response.statusCode.

Cache

Options:

• max: The maximum number of items that can be stored in the cache.

  Default: Infinity.

• maxAge: The maximum age of an item in the cache.

  Default: 0.

• stale: Allow stale items to be returned until they are removed from the cache.

  Default: false.

Methods:
