  yes, right now it just throws an error, there is no special handling on this. perhaps we can consider implementing some kind of fallbackSrc when this happens, but this can also be done right now using helpers.

  here is link that shows how to implement a custom fallback https://playground.jsreport.net/w/anon/qM203vEC

  you need to update the helper call in your hyperlink to be like this

  and in your template have this helper:

  const jsreport = require('jsreport-proxy') const axios = await jsreport.npm.require('axios@0.24.0') async function docxImageWithFallback (options) { const src = options.hash.src if (src.startsWith('data:')) { return src } try { console.log('sending request...') const response = await axios({ url: src, responseType: 'arraybuffer', method: 'GET' }) const contentType = response.headers['content-type'] || response.headers['Content-Type'] if (!contentType) { throw new Error(`Empty content-type for remote image at "${src}"`) } const extensionsParts = contentType.split(';')[0].split('/').filter((p) => p) if (extensionsParts.length === 0 || extensionsParts.length > 2) { throw new Error(`Invalid content-type "${contentType}" for remote image at "${src}"`) } // some servers returns the image content type without the "image/" prefix imageExtension = extensionsParts.length === 1 ? extensionsParts[0] : extensionsParts[1] imageBuffer = Buffer.from(response.data) imgDataUri = `data:image/${imageExtension};base64,${imageBuffer.toString('base64')}` } catch (err) { imgDataUri = 'data:image/png;base64,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' } return docxImage.call(this, { ...options, hash: { ...options.hash, src: imgDataUri } }) }

  You can just hit enter and let it fill the default 5488.
  But installing jsreport app into c:\windows\system32... can cause all kinds of permission problems. I recommend installing it in a normal directory.

  Thanks.
  Could you please confirm or clarify the below regarding child templates and components. I'm really starting to like the new concept, but I need to be sure of the below before taking design decisions.

  I need to know if I have grasped the below correctly and if I missed anything important.

  Child templates called with new syntax {{childTemplate.. }}

  In the child html I get access to this, i.e. the current data context from parent
  Example usage in child {{this.someItemData}} or simply {{someItemData}}

  child templates does NOT have access to data from outer scopes in the parent
  Example: {{../this.name}} will not work in the child

  Helpers in child templates can access the complete report data structure via this
  Example:

  function() { console.log(this.someDataFromTheRoot) }

  child templates can run scripts (i.e. beforeRender..)

  Global helpers are accessible from child templates

  In order to call a template which is not html recipe, I need to inject a recipe change into the childTemplate call.

  Helpers in child templates gets an options object prepended as last argument in calls. The data.root in the options object is the root of the report dataset.

  Components

  In the component html I get access to this, i.e. the current data context from parent, i.e. same as child templates

  Components does NOT have access to data from outer scopes in the parent. Same as child templates.

  Helpers in components can NOT access the complete report data structure via this
  But if I need data from elsewhere in the report data structure I can prepare a special data package to deliver to the component via a wrapper as in your examples.

  Child components can NOT run scripts (i.e. beforeRender..)

  Global helpers are accessible from components

  Components are forced to html recipe, i.e. no need to inject recipe change as for child templates

  Helpers in components gets an options object prepended as last argument in calls. The data.root in the options object is the current context from the parent, i.e. NOT the root from the report dataset.

  Edit:
  I just realized that I can use global helpers to get hold of the report data root even from a component which operates in another context. This could make components usable in every case where I used to have child templates. Does this make sense?

  You are right, you can't expose the whole app through the azure function as far as I know.
  You should use the azure web app or azure VM to get the app running.

  Is there a way i can recreate a folder that goes missing (with the same shortId)? Is this something that could get lost in S3 or is a folder metadata only?

  Yes, just look on another folder and create it the same way. You will need to create s3 folder (folder name) and inside config.json with the following structure.
  

  Or just create the folder with studio and then update the shortid inside config.json.

  You will need to reboot jsreport afterward.

  No, it can't.

  You need to either use a proxy that transforms xml into json.
  Or use a custom jsreport script that actively fetches data from your data source.

  @nisarg170 I see, but just for clarification, this is a different case for what this thread was open for.

  there is no built-in support for multi-tenant support in jsreport, but it is possible by using custom extension code, we do this for example for the jsreportonline service which fetch different parts of our database depending on the tenant that has a session.

  the code for this is public and you can check it here

  Switching back to Handlebars (from jsrender) ?
  • gosanefr

  I understand the concern and I used to prefer using jsrender as well.
  However, Handlebars is just much more popular so we had to target our focus primarily on that. The Handlebars can be more chatty and less natural, but in the end you will reach your goals without big troubles.

  Here are some answers to your questions, but you can typically find the answers quickly at StackOverflow or in the handlebars docs.

  jsrender lets you do the tests directly inside the report like so : {{if someValue >= 2}}print this{{else}}print that{{/if}}. It seems that Handlebars requires to write a function for every single test. Did I miss something?

  https://stackoverflow.com/questions/8853396/logical-operator-in-a-handlebars-js-if-conditional

  it seems that jsrender lets you declare "variables" that you can use throughout the
  templates (with {{* someVar = 2}} ). Does Handlebars provide such a feature?

  You can use with helper, perhaps
  https://handlebarsjs.com/guide/builtin-helpers.html#with
  https://playground.jsreport.net/w/anon/P4y_7rdV

  I like jsrender's itemVar feature that lets you define an alias rather than using the clumsy ../../../field. This is just comfort and readability so I can live without it.

  This can be done with bloc parameters
  https://handlebarsjs.com/guide/block-helpers.html#block-parameters

  Thanks for the quick answer. I will consider going back to Handlebars but the fact that you have to write a function for every single test is really annoying (rather than directly doing something like {{if field>=2}}...{{/if}}). I will create a new thread on the question.

  hi! such warning about the invalid source map was fixed since jsreport 3.7.0, which version do you use? perhaps you just need to update to latest version.
