yaml-edit

Module for editing YAML

Use

Initializing

The yaml editor can be initialized by passing the yaml (string) as a parameter to the require function.

let yamlEdit = require('yaml-edit')(myYamlText)

Alternatively, the editor can be initialized with the init(string text) method

let yamlEdit = require('yaml-edit)();
yamlEdit.init(myYamlText);

Inserting into YAML

Snippets can be added to the YAML with the insertChild(string target, object doc)method. For example:

yamlEdit.init(myInitialYaml);
yamlEdit.insertChild('functions', {
    hello: {
        handler: 'index.handler'
    }        
})

Target can also be a deeper in the hierarchy, e.g.

yamlEdit.insertChild('functions.hello', {
    events: [
        { foo : bar}
    ]
})

If the insert is successful, insertChild() returns null, otherwise (e.g. if the target location cannot be found), it returns an Error

Checking whether a key already exists

Existance of a key can be checked with the hasKey(string target) method. Returns true if the key is found, false otherwise.

Getting the resulting YAML string

The resulting YAML can be returned using the dump() method. E.g.

let output = yamlEdit.dump();

Development

Please run module tests in a Node 4 environment prior to submitting PRs using
