This addin lints and fixes selected JavaScript code or the currently open
file in RStudio. The addin can be helpful for linting JavaScript code
embedded in R Markdown or Shiny apps, in addition to linting whole JavaScript
files. The underlying functions are not exported from js4shiny. If you
want to programmatically lint multiple files, it would be better to use npm
scripts or another JavaScript task running system to lint your files.
Installing StandardJS
standardjs is a
style guide, code linter, and beautifier in one. It is also a command line
tool (standard) for automatically formatting JavaScript code in the
JavaScript Standard Style. The command line tool
will also alert users to common style and programmer errors.
Using standard and this addin requires that node, npm, and standard
be installed on your system. To install node and npm, you need to
install Node.js (they come together). Follow the instructions from Node.js to install these tools. Confirm
that your installation was successful by running npm -v in a new terminal
session. Once npm is available, install standard globally by running
this command in the terminal.
npm install standard --global
