        ]
    }

Options

include

Filter filepath by regex.

Type: RegExp Default: /.*/

Note: Try to never use the default value as this is has a huge impact on speed if all files are matched!

namespace

Type: String Default: all

More info about esbuild namespaces

pattern

Search with Text or Regex and replace the found content with a string.

Type: Array Default: []

All information about the replaceAll regex Options and replacer functions.

Examples:

[
    // transform 2020-10-02 to 02.10.2020
    [/(\d{4})-(\d{2})-(\d{2})/g , (match,p1,p2,p3,offset,wholeString)=>`${p3}.${p2}.${p1}`], 
    ['__buildVersion' , '"1.1.1"'],
    [/(\s*)const(\s+a\s*=\s*1[\s;\n])/g, '$1let$2']
]

Note: /g for globale replacement is a must requirement
