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

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

My work dir:

    • index.template.html
  • server
    • controller
      • docs-renderer.js

// 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,
 index: 'index.html'
 }

 try {
 await send(ctx, sendPath, sendOptions)
 } catch (e) {
 console.log(`[${'send'.magenta} ${'404'.red}] ${ctx.path}`)

module.exports = {

}

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"))

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.

[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?
