There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "We will need to refactor BoardPage to make both routes work."

A block of code is set as follows:

 // Close a card
      if (to.name === 'board' && from.name === 'card') {
        this.closeCardWindow()
        this.openedCard = {}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

 watch: {
    '$route' (to, from) {
      // Switch from one board to another
      if (to.name === from.name && to.name === 'board')

Any command-line input or output is written as follows:

$ mvn install

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "You can click the Attachment button to upload files."
