Perhaps from figwheel. ### Short Answer If at a REPL, inspect: `re-frame.db/app-db`. If at the js console, that's `window.re_frame.db.app_db.state`. You are [using clj-devtools](https://github.com/binaryage/cljs-devtools), right? If not, stop everything and immediately make that happen. ### Better Answer Are you sure you need to? First, you seldom want to inspect all of `app-db`. And, second, inspecting via figwheel will be clumsy. Instead, you probably want to inspect a part of `app-db`. __And__ you probably want to inspect it directly in the GUI itself, not off in a REPL. Here is a useful technique from @escherize. Add something like this to the hiccup of your view ... ```clj [:pre (with-out-str (pprint @interesting))] ``` This assumes that `@interesting` is the value (ratom or subscription) you want to observe (note the @ in front). `pprint` output is nice to read, but not compact. For a more compact view, do this: ```clj [:pre (pr-str @some-atom)] ;; NB: using pr-str instead of pprint ``` If you choose to use `pprint` then you'll need to `require` it within the `ns` of your `view.cljs`: ```clj [cljs.pprint :refer [pprint]] ``` Finally, combining the short and long answers, you could even do this: ```clj [:pre (with-out-str (pprint @re-frame.db/app-db))] ;; see everything! ``` or ```clj [:pre (with-out-str (pprint (:part @re-frame.db/app-db)))] ;; see a part of it! ``` You definitely have [clj-devtools](https://github.com/binaryage/cljs-devtools) installed now, right? ### Other Inspection Tools @yogthos' [json-html library](https://github.com/yogthos/json-html) provides a slick presentation, at the expense of more screen real estate, and the need to include specific CSS. There's also [Data Frisk](https://github.com/Odinodin/data-frisk-reagent) which provides a very nice solution for navigating and inspecting any data structure. *** Up: [FAQ Index](README.md)
