解析 YAML 响应 object - Javascript

Question

Am using swagger-ui, which needs input as in object type. I was trying JSON.parse the YAML response and am getting the below

VM9790:1 Uncaught SyntaxError: Unexpected token s in JSON at position 0
at JSON.parse (<anonymous>)

Please suggest the right way to parse the YAML response to an object

Answer 1

The easiest way to parse a YAML file or response is to use a library for that purpose. You can try https://github.com/eemeli/yaml , which seems fairly well maintained at the time of writing this answer.

Install the library in your project:

npm install yaml

Example usage:

import YAML from 'yaml'
// or
const YAML = require('yaml')


YAML.parse(yamlGoesHere)

Answer 2

Use parseDocument.

package.json

"yaml": "^2.1.3"

import * as yaml from 'yaml';
/*
 Other code
*/
const document = yaml.parseDocument(yourYamlFile);
console.log(document.get('yourKey'));
