turn typescript object into json string

Question

I m trying to initialize an object in typescript which requires a JSON string for the  options  parameter  To be precise it is the object here  The options parameter is required to be a JSON string and not an object for initializing the dijit    Is there a way to create a JSON string from a typescript object without it being a manual process    Please DO NOT link any questions which don t specifically say  TypeScript  as this question specifically relates to TypeScript  While a derivative of JavaScript the way that you write code is different and therefore this is the only post asking this question currently relating to TypeScript

TS gets compiled to JS which then executed  Therefore you have access to all of the objects in the JS runtime  One of those objects is the JSON object  This contains the following methods    JSON parse   method parses a JSON string  constructing the JavaScript value or object described by the string  JSON stringify    method converts a JavaScript object or value to a JSON string    Example    x000D   x000D  const jsonString      employee     name   John    age  30   city   New York       x000D   x000D   x000D  const JSobj   JSON parse jsonString   x000D   x000D  console log JSobj   x000D  console log typeof JSobj   x000D   x000D  const JSON string   JSON stringify JSobj   x000D   x000D  console log JSON string   x000D  console log typeof JSON string   x000D   x000D   x000D

Be careful when using these JSON  parse stringify  methods  I did the same with complex objects and it turned out that an embedded array with some more objects had the same values for all other entities in the object tree I was serializing   const temp       const t         name   name       etc                          a  0                       for  let i   0  i  lt  3  i          const bla   Object assign     t       bla name   bla name   i      bla etc 0  a   i      temp push bla      console log JSON stringify temp

If you re using fs-extra  you can skip the JSON stringify part with the writeJson function  const fsExtra   require  fs-extra     fsExtra writeJson    package json    name   fs-extra     then      gt      console log  success        catch err   gt      console error err
