## Functions



hardCodedResponse(options)ExpressMiddleware


This function is an Express JS middleware which would try to match the specified pattern (from an array of MatchCondition objects)
with req.originalUrl.

- If no match is found, then the request would just pass through.

- If a match is found, then serve the corresponding file (specified in the MatchCondition object) as its hard-coded response.



Note: res.locals['matchedCondition'] is set as per the first-matched-condition



## Typedefs



ExpressMiddleware : function


Express middleware




MatchCondition : Object


The condition to be matched (.pattern is used for match with request and other attributes are used for response)



## hardCodedResponse(options) ⇒ [ExpressMiddleware](#ExpressMiddleware)
This function is an Express JS middleware which would try to match the specified pattern (from an array of MatchCondition objects)
with req.originalUrl.

- If no match is found, then the request would just pass through.

- If a match is found, then serve the corresponding file (specified in the MatchCondition object) as its hard-coded response.



Note: res.locals['matchedCondition'] is set as per the first-matched-condition

**Kind**: global function
**Returns**: [ExpressMiddleware](#ExpressMiddleware) - Express middleware

| Param | Type | Default | Description |
| --- | --- | --- | --- |
| options | Object | | |
| [options.conditions] | [Array.<MatchCondition>](#MatchCondition) | | Array of conditions which would be used for matching with req.originalUrl
A falsy-value (or empty array) would make this function call effectively empty and the request would pass-through |
| [options.verbose] | Boolean | false | truthy-value to log each matched URL and corresponding pattern |
| [options.baseDir] | Object | "<empty-string>" | Base directory for the relative paths |
| [options.debugNote] | Object | "This is a hard-coded response intended for debugging purposes only" | Debug note to be added as HTTP header (and JSON property if MatchCondition says .type is 'json')
- If responseText & responseFile are not provided in MatchCondition, then debugNote is used as the response
- Set it to false to disable it |
| [options.console] | Object | console | A logging/console object, which supports .log() and .warn() |

## ExpressMiddleware : function
Express middleware

**Kind**: global typedef

| Param | Type | Description |
| --- | --- | --- |
| req | Object | Request object |
| res | Object | Response object |
| next | function | Next function |

## MatchCondition : Object
The condition to be matched (.pattern is used for match with request and other attributes are used for response)

**Kind**: global typedef
**Properties**

| Name | Type | Default | Description |
| --- | --- | --- | --- |
| pattern | String | | "none" or falsy-value would match none
"*" or "all" would match all
"<any-other-pattern>" would be searched as plain string anywhere in the req.originalUrl |
| status | String | 200 | Response status |
| type | String | | Type of response (currently supporting 'json')

If 'json' is used:
- responseFile's contents would be read as commented-json (CJSON) and the commentes would be stripped-off.
- 'Content-Type' header is set as 'application/json; charset=utf-8' by default, unless overridden using contentType option.
- debugNote would be added as a property to the JSON response (this can be overwritten through the options when setting up the middleware). |
| contentType | String | | 'Content-Type' header |
| responseText | String | | The text to be used as the hard-coded response (responseText has more priority than responseFile) |
| responseFile | String | | The file to be used as the hard-coded response (responseText has more priority than responseFile) |
| Any-other-object-properties | \* | | Any other object properties (these might be accessed after match from res.locals['matchedCondition']) |
