You could also read the HTML file and send it   app get       req  res    gt        fs readFile   dirname     public index html    utf8    err  text    gt            res send text

If you re using express  3 0 0 change the line below from your example   app use express staticProvider   dirname     public       to something like this   app set  view options    layout  false    app use express static   dirname     public       I made it as described on express api page and it works like charm  With that setup you don t have to write additional code so it becomes easy enough to use for your micro production or testing   Full code listed below   var express   require  express    var app   express createServer     app set  view options    layout  false    app use express static   dirname     public      app get      function req  res        res render  index html         app listen 8080   127 0 0 1

I didn t want to depend on ejs for simply delivering an HTML file  so I simply wrote the tiny renderer myself   const Promise   require   bluebird     const fs        Promise promisifyAll  require   fs        app set   view engine    html     app engine    html     filename  request  done     gt        fs readFileAsync  filename   utf-8             then  html   gt  done  null  html              catch  done

With Express 4 0 0  the only thing you have to do is comment out 2 lines in app js      app set  views   path join   dirname   views     app set  view engine    jade         or whatever the templating engine is    And then drop your static file into the  public directory  Example   public index html

From the Express js Guide  View Rendering     View filenames take the form Express ENGINE  where ENGINE is the name of the module that will be required  For example the view layout ejs will tell the view system to require  ejs    the module being loaded must export the method exports render str  options  to comply with Express  however app register   can be used to map engines to file extensions  so that for example foo html can be rendered by jade    So either you create your own simple renderer or you just use jade    app register   html   require  jade       More about app register      Note that in Express 3  this method is renamed app engine

If you want to render HTML file you can use sendFile   method  without using any template engine const express    require  quot express quot   const path   require  quot path quot   const app   express   app get  quot   quot   req res   gt       res sendFile   path join   dirname   htmlfiles  index html         app listen 8000     gt       console log  quot server is running at Port 8000 quot        I have an HTML file inside htmlfile so I used path module to render index html  path is default module in node  if your file is present in root folder just used res sendFile path join   dirname   htmlfiles  index html     inside app get   it will work

if you are using express framework to node js   install npm ejs   then add config file   app set  port   process env PORT    3000   app set  views     dirname     views    app set  view engine    ejs    app set  view engine    jade    app use express favicon     app use express logger  dev     app use express bodyParser     app use express methodOverride     app use app router       render the page from exports module form js have the html file in the views dir    with extension of ejs file name as form html ejs  then create the form js  res render  form html ejs

If you are trying to serve an HTML file which ALREADY has all it s content inside it  then it does not need to be  rendered   it just needs to be  served   Rendering is when you have the server update or inject content before the page is sent to the browser  and it requires additional dependencies like ejs  as the other answers show   If you simply want to direct the browser to a file based on their request  you should use res sendFile   like this   const express   require  express    const app   express    var port   process env PORT    3000    Whichever port you want to run on app use express static    folder with html       This ensures local references to cs and js files work  app get       req  res    gt      res sendFile   dirname     folder with html index html         app listen port       gt  console log  lifted app  listening on port     port      This way you don t need additional dependencies besides express  If you just want to have the server send your already created html files  the above is a very lightweight way to do so

Many of these answers are out of date   Using express 3 0 0 and 3 1 0  the following works   app set  views     dirname     views    app engine  html   require  ejs   renderFile     See the comments below for alternative syntax and caveats for express 3 4    app set  view engine    ejs      Then you can do something like   app get   about   function  req  res        res render  about html          This assumes you have your views in the views subfolder  and that you have installed the ejs node module  If not  run the following on a Node console   npm install ejs --save

It is very sad that it is about 2020 still express hasn t added a way to render an HTML page without using sendFile method of the response object  Using sendFile is not a problem but passing argument to it in the form of path join   dirname   relative path to file   doesn t feel right  Why should a user join   dirname to the file path  It should be done by default  Why can t the root of the server be by defalut the project directory  Also  installing a templating dependency just to render a static HTML file is again not correct  I don t know the correct way to tackle the issue  but if I had to serve a static HTML  then I would do something like   const PORT   8154   const express   require  express    const app   express     app use express static  views      app listen PORT       gt        console log  Server is listening at port http   localhost   PORT           The above example assumes that the project structure has a views directory and the static HTML files are inside it  For example  let s say  the views directory has two HTML files named index html and about html  then to access them  we can visit  localhost 8153 index html or just localhost 8153  to load the index html page and localhost 8153 about html to load the about html  We can use a similar approach to serve a react angular app by storing the artifacts in the views directory or just using the default dist  lt project-name gt  directory and configure it in the server js as follows   app use express static  dist  lt project-name gt

I wanted to allow requests to     to be handled by an Express route where previously they had been handled by the statics middleware  This would allow me to render the regular version of index html or a version that loaded concatenated   minified JS and CSS  depending on application settings  Inspired by Andrew Homeyer s answer  I decided to drag my HTML files - unmodified - into a views folder  configure Express like so     app engine  html   swig renderFile      app set  view engine    html       app set  views     dirname     views        And created a route handler like so    app route               get function req  res               if config useConcatendatedFiles                   return res render  index-dist                              res render  index                         This worked out pretty well
