yaml example file strings

The YAML file example contains all the components of the YAML file.

The official standard of file extension is .yaml.

Let’s see a sample yaml document with components syntax.


---  # yaml document beginning
# comment syntax

# basic syntax - key and value separated by colon and space before the value
key: value

# Scalar data types
integerValue: 1                     # integer value
floatingValue: 1                     # floating vale

stringValue: "456"                   # string with double quotes
stringValue: 'abc'                  # string with single quotes
stringValue: wer                   # string without quotes

booleanValue:true                   # boolean values - true or false


# Multiline string with literal block syntax -preserved new lines
string1: |
   Line1
   line2
   "line3"
  line4

# Multiline strings with folded block syntax - new lines are not preserved, leading and trailing spaces are ignore
  string1: >
   Line1
   line2
   "line3"
  line4
