connect-inject

connect middleware for adding any script to the response, this is a forked version of connect-livereload.

This is a slightly modified version of connect-livereload all the credits go to the author.

For further documentation refer to the author's repo connect-livereload.

install

bash
npm install connect-inject --save-dev
git
git clone https://github.com/danielhq/connect-inject.git

use

this middleware can be used to inject any sort of content into the webpage e.g. [Livereload, Weinre etc]

snippet: string | Array

snippet now accepts either string or an array which will be inserted at the bottom of the page by default.

connect/express example

javascript
  app.use(require('connect-inject')({
    snippet: "<script>alert('hello world');</script>"
  }));

options

Options are not mandatory: app.use(require('connect-inject')()); The Options have to be provided when the middleware is loaded:

e.g.:

app.use(require('connect-inject')({
  snippet: "<script>alert('hello world');</script>",
  ignore: ['.js', '.svg']
}));

These are the available options with the following defaults:

javascript
  // these files will be ignored
  ignore: ['.js', '.css', '.svg', '.ico', '.woff', '.png', '.jpg', '.jpeg'],

  // this function is used to determine if the content of `res.write` or `res.end` is html.
  html: function (str) {
    return /<[:_-\w\s\!\/\=\"\']+>/i.test(str);
  },

  // rules are provided to find the place where the snippet should be inserted.
  // the main problem is that on the server side it can be tricky to determine if a string will be valid html on the client.
  // the function `fn` of the first `match` is executed like this `body.replace(rule.match, rule.fn);`
  // the function `fn` has got the arguments `fn(w, s)` where `w` is the matches string and `s` is the snippet.
  rules: [{
    match: /<\/body>/,
    fn: prepend
  }, {
    match: /<\/html>/,
    fn: prepend
  }, {
    match: /<\!DOCTYPE.+>/,
    fn: append
  }],


  // snippet taks a string argument which can be anything you want, and will be appended (by default) before </body> tag
  snippet: "<script>alert('hello world');</script>"

grunt example

The following example is from an actual Gruntfile that uses grunt-contrib-connect

javascript
connect: {
  options: {
    port: 3000,
    hostname: 'localhost'
  },
  dev: {
    options: {
      middleware: function (connect) {
        return [
          require('connect-inject')({ snippet: "<script>alert('hello world');</script>"}),
          mountFolder(connect, '.tmp'),
          mountFolder(connect, 'app')
        ];
      }
    }
  }
}

For use as middleware in grunt simply add the following to the top of your array of middleware.

javascript
  require('connect-inject')(),

You can pass in options to this call if you do not want the defaults.

dev is simply the name of the server being used with the task grunt connect:dev. The other items in the middleware array are all functions that either are of the form function (req, res, next) like checkForDownload or return that like mountFolder(connect, 'something').
