I work on a lot of Javascript projects. The fashion in Javascript is to use build tools like Gulp or Webpack that are written and configured in Javascript. I want to talk about the merits of Make (specifically GNU Make).

Make is a general-purpose build tool that has been improved upon and refined continuously since its introduction over forty years ago. Make is great at expressing build steps concisely and is not specific to Javascript projects. It is very good at incremental builds, which can save a lot of time when you rebuild after changing one or two files in a large project.

Make has been around long enough to have solved problems that newer build tools are only now discovering for themselves.

Despite the title of this post, Make is still widely used. But I think that it is underrepresented in Javascript development. You are more likely to see a Makefile in a C or C++ project, for example.

My guess is that a large portion of the Javascript community did not come from a background of Unix programming, and never had a good opportunity to learn what Make is capable of.

I want to provide a quick primer here; I will go over the contents of the Makefile that I use with my own Javascript projects.

A PKGBUILD is a shell script containing the build information required by Arch Linux packages.

Packages in Arch Linux are built using the makepkg utility. When makepkg is run, it searches for a PKGBUILD file in the current directory and follows the instructions therein to either compile or otherwise acquire the files to build a package archive (pkgname.pkg.tar.xz). The resulting package contains binary files and installation instructions, readily installable with pacman.

Mandatory variables are pkgname, pkgver, pkgrel, and arch. license is not strictly necessary to build a package, but is recommended for any PKGBUILDs shared with others, as makepkg will produce a warning if not present.

It is a common practice to define the variables in the PKGBUILD in same order as given here. However, this is not mandatory, as long as correct Bash syntax is used.
