Just try this instead    res sendFile  public index1 html      root     dirname      This worked for me  the root   dirname will take the address where server js is in the above example and then to get to the index1 html   in this case  the returned path is to get to the directory where public folder is

The express static middleware is separate from res sendFile  so initializing it with an absolute path to your public directory won t do anything to res sendFile   You need to use an absolute path directly with res sendFile  There are two simple ways to do it    res sendFile path join   dirname      public    index1 html     res sendFile  index1 html     root  path join   dirname      public         Note    dirname returns the directory that the currently executing script is in  In your case  it looks like server js is in app   So  to get to public  you ll need back out one level first     public index1 html   Note  path is a built-in module that needs to be required for the above code to work  var path   require  path

An alternative that hasn t been listed yet that worked for me is simply using path resolve with either separate strings or just one with the whole path      comma separated app get      function req  res        res sendFile  path resolve  src    app    index html            Or     just one string with the path app get      function req  res        res sendFile  path resolve  src app index html             Node v6 10 0   Idea sourced from https   stackoverflow com a 14594282 6189078

If you want to set this up once and use it everywhere  just configure your own middleware  When you are setting up your app  use the following to define a new function on the response object   app use  req  res  next    gt      res show    name    gt        res sendFile   public   name     root    dirname           next          Then use it as follows   app get   demo    req  res    gt      res show  index1 html

res sendFile    dirname     public      index1 html       where   dirname will manage the name of the directory that the currently executing script   server js   resides in

Another way to do this by writing less code   app use express static  public      app get      function req  res       res sendFile  index html

Based on the other answers  this is a simple example of how to accomplish the most common requirement   const app   express   app use express static  public       relative path of client-side code app get      function req  res        res sendFile  index html     root    dirname       app listen process env PORT    This also doubles as a simple way to respond with index html on every request  because I m using a star   to catch all files that weren t found in your static  public  directory  which is the most common use case for web-apps  Change to   to return the index only in the root path

you can use send instead of sendFile so you wont face with error  this works will help you   fs readFile  public index1 html   err data   gt   if err     consol log err    else   res setHeader  Content-Type    application pdf      for telling browser that your response is type of PDF  res setHeader  Content-Disposition    attachment  filename  your file name for client pdf      if you want that file open immediately on the same page after user download it write  inline  instead attachment in above code   res send data
