在长字符串上附加nodeca / js-yaml>-

Question

Using js-yaml npm package, i'm trying to manipulate a .yaml file. while successfully able to manipulate, i'm getting a problem while saving a long string.

Actual:

  abvs_adas: >-
    c2Rhc2Rhc2Rhc2Rhc2RwaW9qbGtkZ2hqbGtzZGhmZ2psaGFzamhhandiZm0sYXNibmYsbWFuc2Y==`

Expected

  abvs_adas: c2Rhc2Rhc2Rhc2Rhc2RwaW9qbGtkZ2hqbGtzZGhmZ2psaGFzamhhandiZm0sYXNibmYsbWFuc2Y==`

when setting {lineWidth: 200} it became as the expectes, but when i got a base64 string containing 6000 chars, it appended that >- again (i've set increased {lineWidth: 20000} .

how can i not have this >- appended ?

I'm using nodeyaml package, doing: nodeyaml.write('bla.yaml', doc, {lineWidth: 200}, function (err) { .. } which internally does:

 await fs.writeFile(filename, yaml.dump(object, opts), {encoding, flag})

where

opts = {lineWidth: 20000}

object = doc

I've used js-yaml , but if you know an alternative which does:

1. load a .yaml which includes a very large strings
2. manipulate it
3. save it.

it's great.

Answer 1

{lineWidth: -1} does the trick.

Explanation; inside the js-yaml package there is function named: chooseScalarStyle which sets the style, and the chosen style is: STYLE_FOLDED which later appending that >-\\n .

while setting {lineWidth: -1} it make the style: STYLE_PLAIN which later just return the string as is.
