How do I do a multi-line string in node js

Question

With the rise of node js  multi-line strings are becoming more necessary in JavaScript    Is there a special way to do this in Node JS  even if it does not work in browsers  Are there any plans or at least a feature request to do this that I can support    I already know that you can use  n  at the end of every line  that is not what I want

What exactly are you looking for when you mean multiline strings.

Are you looking for something like:

var str = "Some \
    String \
    Here";

Which would print as "Some String Here"?

If so, keep in mind that the above is valid Javascript, but this isn't:

var str = "Some \ 
    String \
    Here";

What's the difference? A space after the \. Have fun debugging that.

node v4 and current versions of node  As of ES6  and so versions of Node greater than v4   a new  template literal  intrinsic type was added to Javascript  denoted by back-ticks      which can also be used to construct multi-line strings  as in    this is a  single string    which evaluates to   this is a nsingle string    Note that the newline at the end of the first line is included in the resulting string   Template literals were added to allow programmers to construct strings where values or code could be directly injected into a string literal without having to use util format or other templaters  as in   let num 10   console log  the result of   num  plus   num  is   num   num        which will print  the result of 10 plus 10 is 20   to the console   Older versions of node  Older version of node can use a  line continuation  character allowing you to write multi-line strings such as    this is a   single string    which evaluates to   this is a single string     Note that the newline at the end of the first line is not included in the resulting string

In addition to accepted answer    this is a  single string    which evaluates to   this is a nsingle string    If you want to use string interpolation but without a new line  just add backslash as in normal string    this is a   single string        this is a single string    Bear in mind manual whitespace is necessary though    this is a  single string        this is asingle string

As an aside to what folks have been posting here  I ve heard that concatenation can be much faster than join in modern javascript vms  Meaning   var a       hey man  this is on a line      and this is on another      and this is on a third    join   n      Will be slower than   var a    hey man  this is on a line n              and this is on another n             and this is on a third         In certain cases  http   jsperf com string-concat-versus-array-join 3  As another aside  I find this one of the more appealing features in Coffeescript  Yes  yes  I know  haters gonna hate   html               lt strong gt           cup of coffeescript         lt  strong gt               Its especially nice for html snippets  I m not saying its a reason to use it  but I do wish it would land in ecma land  -    Josh

Take a look at the mstring module for node js      This is a simple little module that lets you have multi-line strings in JavaScript       Just do this       var M   require  mstring        var mystring   M function          Ontario   Mining and   Forestry   Group               to get      mystring      Ontario nMining and nForestry nGroup       And that s pretty much it       How It Works   In Node js  you can call the  toString method of a function  and it will give you the source code of the function definition  including any comments  A regular expression grabs the content of the comment       Yes  it s a hack  Inspired by a throwaway comment from Dominic Tarr      note  The module  as of 2012 13 11  doesn t allow whitespace before the closing       so you ll need to hack it in yourself

Vanilla Javascipt does not support multi-line strings   Language pre-processors are turning out to be feasable these days   CoffeeScript  the most popular of these has this feature  but it s not minimal  it s a new language   Google s traceur compiler adds new features to the language as a superset  but I don t think multi-line strings are one of the added features   I m looking to make a minimal superset of javascript that supports multiline strings and a couple other features   I started this little language a while back before writing the initial compiler for coffeescript   I plan to finish it this summer   If pre-compilers aren t an option  there is also the script tag hack where you store your multi-line data in a script tag in the html  but give it a custom type so that it doesn t get evaled   Then later using javascript  you can extract the contents of the script tag   Also  if you put a   at the end of any line in source code  it will cause the the newline to be ignored as if it wasn t there   If you want the newline  then you have to end the line with   n
