Was installed and configured the eslint and prettier to keep the code clean and patterned.

Configure

Access Grex repository page and download the linux distribution into dependencies/bin. Then zip the dependencies folder:

cd dependencies
zip -yr ../dependencies.zip .
cd ..

Or using 7zip:

cd dependencies
7z a ../dependencies.zip *
cd ..

For those that for any reason are not able to download the binary or compact your own package this repository is shipped with one package ready for use.

Then, deploy the API:

$ sls deploy

Usage

Refer to the Grex documentation, send the parameters and flags in the body of the request:

{
  "terms": [
    "sample",
    "example",
    "simple"
  ],
  "flags": ["x"]
}

Output:

^
  (?:

  mple
$

There are only a few flags not available:

• -c, --colorize
