Default configuration

preos comes with a set of pre-configured preprocessors to use just only requiring the library:

Default transpilers:

  • To JavaScript [js]:
  • To CSS [css]:
  • To HTML [html]:
    • PUG: [pug]: require the compilerOptions property to fill the pattern.
    • VUE: [vue]: returns a 'compiled' version of itself. More information here.
  • To JSON [json]:

Default interpreters:

  • JavaScript [js]: executes itself.
  • TypeScript [ts]: transpiles the code into js and then executes it.
  • PUG [pug]: returns a function that accepts an object with the properties to fill the template and then returns its equivalent code in html.
  • VUE [vue]: returns a function that lazily will compile the template and returns an object prepared for be use with the Vue library.
  • JSON [json]: returns an object that represents its structure.
  • XML [xml]: returns an object that represents its structure. More information here.
  • TOML [toml]: returns an object that represents its structure.
