nv-buf-data-to-code
convert a js_value to js_code
support most js_value, but NOT include: function, class, lambda, generator, iterator, promise, weakmap,weakset,weakref-if-deref-failed, native-func
for generate coding-template AND fast-copy FIXED-DATA
this is used for collecting data IN your application, AND then insert the generated code to a DATABASE
IF you collected enough, you can use them to creat FIXED-SHAPE-FILE
install
- npm install nv-buf-data-to-code
usage
nodejs cp ./DIST/nd.js
const {to_code,to_script) = require("./DIST/nd.js");
to_code(any_js_value,indent=" ") -> string;
