 1 | # repl.history
 2 | 
 3 | Persist a node repl's history to a file.
 4 | 
 5 | ## from node
 6 | 
 7 | install: `npm install repl.history`
 8 | 
 9 | ```javascript
10 | var os = require('os');
11 | var path = require('path');
12 | 
13 | var historyFile = path.join(os.homedir(), '.node_history');
14 | 
15 | var repl = require('repl').start('> ');
16 | require('repl.history')(repl, historyFile);
17 | ```
18 | 
19 | this will drop a `.node_history` file in your home directory.
20 | 
21 | ## from the command line
22 | 
23 | install: `npm install -g repl.history`
24 | 
25 | run `repl.history` on the command line
26 | 
27 | A file `~/.node_history` will be created.
28 | 
29 | I like to alias it to `nr` for node repl
