Error: Cannot find module 'documentation'

[bobbrowning]

I am trying to use the API. I installed documention.js (13.2.5) using npm (6.14.16) and it is working fine from the command line. However this does not generate a module in node_modules and when I run a program with

var documentation = require('documentation');

I get

Error: Cannot find module 'documentation'

How do I install the module. I can't find instructions in the documentation..

I have a workaround at lease...
exec(
documentation build ./bin/suds/admin.js --shallow -f md | markdown,
....

Lacks elegance but works for my purposes.

The default instructions - npm install -g documentation - are to install documentation globally, as a command-line tool. If you'd like to install it locally, so you can use it with require, you can drop the -g argument and run npm install documentation

Thanks. I eventually found the module in /lib and tried requiring it from there, but came up with an error so abandoned that approach. I just re-installed documentation as suggested and I am getting the same error.

The code
let documentation=require ('documentation');
let sendView = require('./suds/send-view');

module.exports = async function (req, res) {
documentation.build([req.query.file])
.then(documentation.formats.html)
.then(output => {
let result = sendView(res, 'report', output);
});
return('OK');
}

req.query.field has the path/file name (./suds/db.js) and sendView sends the results to the screen.

This doesn't work on version 14.0.3 or later.

$ cat require.js

const doc = require('documentation')
console.log(doc)

Yes, looks like the changelog mentions updating to node v14 but not the move to native esm.

You'll need to use import for 14.x
