Using custom scripts Unfinished / May change

How it works

Perform a post/get request towards a js file, This js file will be checked for a key (Security) and with the correct key, the document will temporarily append the script and will execute the requested script

As a security feature, you must have the request path and a key programed in a .swsswsaccess file and in the js file. The file name does not need to end with .js The extension can be anything you want as the extension does not matter and will not be checked You do not need to have swsaccess enabled, this does not enable swsaccess. It is just easier to keep everything in 1 place It is recommended to have the log to file function on, so it is easier to see if something goes wrong


While not required, it is very highly recommended to turn on the swsaccess feature, as it will block users from performing a get request towards the file.

Writing the swsaccess file

The file needs to be in the same path as the requested file The file name should be .swsswsaccess (case sensitive) Example:

For info on how to write for a get request, please read the swsaccess readme

        "type": "POSTkey",
        "request_path": "index.js",
        "key": "wa4e76yhefy54t4a"

Change request_path to the file you would like to perform this towards Change key to a random string of numbers and letters Do not change type

Adding key verification to the .js file

Add the following line to your swsaccess file

postKey = 'wa4e76yhefy54t4a'

Change wa4e76yhefy54t4a to the value of the key that you had inputted into the swsaccess file The start of the line (postKey = ) MUST STAY THE SAME (case sensitive). The server does not check for a set variable, but it will scan the file for the text postKey THIS LINE MUST BE ITS OWN LINE!! You CANNOT combine multiple lines of code with ; Indenting this line may cause for the server to not find this line and in result, the code will not be executed YOU CANNOT PUT SPACES, ", or ' IN YOUR KEY


Writing the code inside the file


res.contentType('text/plain') // ALWAYS set the headers first
res.write('test') // THEN send the data
res.end() // THEN end the request

res contains all the functions to respond, while req contains all the request information

NOTE - You can use BOTH server side javascript and Server Side POST in the same file! Just declare 2 separate keys in the swsaccess and in the file!

To Debug the code, open the main window and press ctrl + shift + i

res Commands

res.end(): function

This function MUST be called at the end of the file. If called before finished processing, the server will cut off your script This function will close the http request You can use this function directly when finished and it will automatically respond with an http code of 200 (unless set otherwise)

res.write(data, httpCode): function

data: String || Buffer || ArrayBuffer This function will write data to the client. Once called, you cannot push any more information.

res.setHeader(headerType, headerValue): function

This function will set headers of the response. Instead of Cookie: name=value, you would put res.setHeader('Cookie', 'name=value')

res.contentType(type): function

This function will set the content type to respond with, you could also use the res.setHeader() function

res.writeCode(httpCode): function

Call this to respond with no message. Dont forget to finish with res.end()

res.renderFileContents(file): function

Once you have called the file with res.getFile() (DO NOT use the file.file() function) use res.renderFileContents() to render the file DO NOT call res.end() when using this function Example:

`res.getFile('../somefile.html', function(file) {
    if (file.error) {
    } else if (file.isFile) {
    } else if (file.isDirectory) {
        file.getDirContents(function(results) {
            results[2].file(function(file2) {

Chunked encoding

res.writeChunk(data): function

data: String || Buffer || ArrayBuffer This feature will send the data in chunks, instead of all at once. To enable, you must set the transfer-encoding header to chunked Like this: res.setHeader('transfer-encoding','chunked')


res.contentType('text/html; charset=utf-8')
res.writeChunk('This is Chunk number 1')
res.writeChunk('\n\nAnd this is chunk number 2')
res.writeChunk('\n\nAnd this is the last chunk')
res.end() // VERY IMPORTANT (as always)

req Commands

req.bodyparams: If the request is made with the html form element, then this will have all the values of the form

req.headers: json string

This contains all of the headers that the user sent when making the http request

req.arguments: json string

This contains all of the arguments that the user has put in the url

req.method: string

This contains the request method

req.uri: string

This contains the entire requested path

req.origpath: string

This contains the requested file (Will end with / if is directory)

req.path: string

This contains the requested file. (Will NOT end with / if is directory)


res.getFile(path, callback): function

This function will read a file. Relative urls are supported. To get the directory contents, use the file.getDirContents() function To read the file as text, use the file.file() function Example:

`res.getFile('../test.txt', function(file) {
    if (file.error) {
    } else if (file.isFile) {
            var filetext = text // file.file will read the file as text. To render the file, you can use the renderFileContents() function
    } else if (file.isDirectory) {
        file.getDirContents(function(results) {
            results[2].file(function(file) {

res.writeFile(path, data, allowReplaceFile, callback): function

This function will save a file path: the path of the file If the path contains a non existent folder, the folder will be created data: string/Buffer/ArrayBuffer of the file. DO NOT SEND OTHER TYPES OF DATA - THIS COULD BREAK THE APP (Just refresh it) allowReplaceFile: if file exists and you want to replace the file, set this to true callback: function will be executed to tell you if there was an error or it will callback the file

res.deleteFile(path, callback): function

This function will delete path: the path of the file callback: function will be executed to tell you if there was an error or success

Commands once you get the info using the res.getFile() function


promise: entry.filePromise() This function will read the file and return the contents as a Buffer. If you want to display the contents of the file, it is recommended to use res.renderFileContents() This function will only work on files, not directories


promise: entry.textPromise() Will read the file as text


promise: entry.removePromise() Use this to delete the file


promise: entry.getDirContentsPromise() This function will get the contents of the directory in an array. Every file in the array will work with the .file and the .getDirContents functions This function will only work on directories, not files From here, you can use the contents to use in the rest of the processing.

If you would like to render the directory listing with the results, you can use these commands. When the directory listing is sent, you still need to send res.end()


Will send a stringified json of the directory listing


Will send a directory listing that can transition between javascript and static


Will send a the default javascript directory listing


Will send a plain, static directory listing

Promise based fs functions

Same use as functions above, just uses promises to use await or .then when reading the file.


res.writeFilePromise(path, data, allowReplaceFile)


Processing the request body


callback: function

Will read from the req stream. If the body has already been read, it will return the existing body After calling this, req.body will be set


res.readBody(function(body) {


Same as res.readBody, but uses promises


// When inside an async function
var body = await res.readBodyPromise()
// or
res.readBodyPromise().then(function(body) {

stream2File(writePath, allowOverWrite, callback)

writePath: path to save file to allowOverWrite: allow file overwrite, true or falsecallback: function. Will return if there is an error, or success

stream request body to file. Saves memory on larger requests

Requiring modules

First, you MUST require a file through the requireFile function. In the folder that has the module you required, you can open a terminal/command prompt window and install the modules you want. Then, inside the file you required, you can require the modules you installed

You CANNOT require modules inside the main file the requireFile function is only for use in the main file

To clear module cache: call the clearModuleCache function

Another Useful Tool

global.tempData: json This global variable is a place that you can store data if you need. It will NOT be cleared after the end of the response.

The appInfo variable will tell you which server you are using
