docsify-server-renderer error

[ccforeverd]

My code here:

// docs-renderer.js
const fs = require('fs')
const path = require('path')
const docsifyRenderer = require('docsify-server-renderer')
const templatePath = path.resolve(__dirname, '../../docs/index.template.html')

const docsifyConfig = {
  basePath: '/src',
  // ...
}

const renderer = new docsifyRenderer({
  template: fs.readFileSync(templatePath, 'utf-8'),
  config: docsifyConfig
})

async function test () {
  renderer.renderToString('docs/')
    .then(console.log)
    .catch(console.log)
}

test()

module.exports = renderer

Then:

TypeError: Cannot read property 'indexOf' of undefined

    at bootstrapNodeJSCore (internal/bootstrap/node.js:739:3)

There is shotcut of docsify-server-renderer/build.js

// line 553
  var curFileName = this$1.router.parse().file;
// line 346-360
  AbstractHistory.prototype.parse = function parse (path$$1) {
    var query = '';

    var queryIndex = path$$1.indexOf('?');
    if (queryIndex >= 0) {
      query = path$$1.slice(queryIndex + 1);
      path$$1 = path$$1.slice(0, queryIndex);
    }

    return {
      path: path$$1,
      file: this.getFile(path$$1),
      query: parseQuery(query)
    }
  };

I think maybe there is something wrong with my code or build.js after rollup-build, pls help me to check it.

Best

// src/server/router/docs.js

require('colors')
const path = require('path')
const send = require('koa-send')
const renderer = require('../controller/docs-renderer')

const docsDir = path.resolve(__dirname, '../../docs')

const routerName = 'docs'
const routerPath = '/docs/(.*)?'
const routerHandler = async ctx => {
  const sendPath = ctx.path.replace(`/${routerName}`, '') || '/'
  const sendOptions = {
    root: docsDir,

When i visit http://localhost:3333/docs#/, it's all OK with router model hash. But if i try ssr, there is allways a error of parse.

Pls see:

docsify/src/core/render/compiler.js

Line 121 in a257a4a

const curFileName = this.router.parse().file

docsify/src/core/router/history/abstract.js

Line 10 in a257a4a

parse(path) {

The method parse real need an argument of path

I have the same problem

const Renderer = require('docsify-server-renderer')
const readFileSync = require('fs').readFileSync
const express = require ('express');

const app = express();

let renderer = new Renderer({
    template: readFileSync('./docs/index.template.html', 'utf-8'),
    config: {
        name: 'Test',
        basePath: '/docs',
        repo: 'te/st',
        loaddNavbar: true, 
        loadSidebar: true, 
        subMaxLevel: 3, 
        auto2top: true
    }
})
app.get('*', (req, res) =>{
    renderer.renderToString(req.url, (html, err) =>{
        if(err) throw err
        console.log(html)
    })
})
app.listen(3000, console.log("RUNING ON PORT 3000"))

[bitkris-dev]

I've the exact same error. I'm trying to use docsify with SSR using docsify-server-renderer but seems impossible. Also, the documentation talks about a renderer.renderToString(url) but it's not explained what the "url" parameter should be.

@QingWei-Li Can you take a look, please?

[jthegedus]

Has anyone been able to identify which was the last working version of docsify?

About docsify-server-renderer/build.js, even if you change this ...

// line 346-360
  AbstractHistory.prototype.parse = function parse (path$$1) {
    var query = '';

    var queryIndex = path$$1.indexOf('?');
    if (queryIndex >= 0) {
      query = path$$1.slice(queryIndex + 1);
      path$$1 = path$$1.slice(0, queryIndex);
    }

    return {
      path: path$$1,
      file: this.getFile(path$$1),
      query: parseQuery(query)
    }
  };

by ... (around line 349)

// line 346-360
  AbstractHistory.prototype.parse = function parse (path$$1) {
    var query = '';
    var queryIndex = -1;                             // new
    if (path$$1) queryIndex = path$$1.indexOf('?');  // edited
    if (queryIndex >= 0) {
      query = path$$1.slice(queryIndex + 1);
      path$$1 = path$$1.slice(0, queryIndex);
    }

    return {
      path: path$$1,
      file: this.getFile(path$$1),
      query: parseQuery(query)
    }
  };

It works apparently or simply avoid the error. But I got another situation, may be with the basePath, because the README.md file don't load.
I don't know if I'm wrong, but it seems that if you use docsify-cli it doesn't render the content for better SEO either.

Same error! Just download https://github.com/docsifyjs/docsify-ssr-demo
npm install
npm start

[zmnv]

All works with old 4.1.7 version.

"docsify-cli": "^4.1.7",

Last version 4.3.0 returns error

[zmnv]

No. Something wrong.. Can you update docsify-cli or ssr example repo, pls?

[llwor94]

i'm having the same issue... anyone have any luck?

[wll8]

It seems that the examples on docsify-ssr-demo are incomplete and incorrect.
I don't know why.

I don't know how https://docsify.now.sh/ssr is implemented.

git clone https://github.com/docsifyjs/docsify-ssr-demo
cd docsify-ssr-demo
npm i 
npm start

git clone https://github.com/docsifyjs/docsify

[mattvb91]

Still having this issue. Did anyone manage to find a fix?

[boxsnake]

I looked around the code, and found the possible reason:

• It seems that the "main" render part resolve relative paths to absolute paths before rendering.
• And when _renderFile is called, for absolute paths, the function uses fetch to get file.
• Since fetch is not available for local files without a file:// scheme, the fetch won't work.
• As a result, the content is empty.

[equinusocio]

Same here with v4.4.1. Is the fix already released?
