Meteor has launched a brand new model, 2.13, with some updates and enhancements. Listed below are a few of the key options of this launch:
new Blaze.js launch and high quality of life updates, and far more!
As you might have seen on this put up within the boards by our CEO Fred Maia and within the earlier launch weblog put up, we’re making safety updates for Node.js. The PR which added the safety updates is right here. Here’s a hyperlink to a Dockerfile the place you should use the Node with the safety updates.
When you’ve got any issues or doubts about this matter, please ping us together with your query.
On this minor replace, we acquired a long-wanted characteristic, the opportunity of dealing with async values in templates. You possibly can examine the docs for it right here. This characteristic was attainable because of the exhausting work of @radekmie in #412 and #413.
Listed below are some snippets on methods to use async in Blaze now:
Easy values
<template title="foo">
{{#let title=getName}}
{{#if @pending 'title'}}
We're fetching your title...
{{/if}}
{{#if @rejected 'title'}}
Sorry, an error occured!
{{/if}}
{{#if @resolved 'title'}}
Hello, {{title}}!
{{/if}}
{{/let}}
</template><script>
Template.foo.helpers({
getName: async () => {
const sleep = ms => new Promise(r => setTimeout(r, ms));
await sleep(1000);
return 'john'
},
});
</script>
It will render whereas getting the title for 1000ms, We're fetching your title..., then it is going to render the string john
In Meteor.js v2.8, it was addedMeteor.callAsync, which means that doing a Meteor.callAsync("someMethod") will lead to a promise of the results of that decision. In lots of instances, you need to return an inventory. For such instances, we’ve this snippet the place you’ll be able to iterate over an async checklist:
<template title="hyperlinks">
{{#let hyperlinks=getLinksFromDB}}
{{#if @pending}}
We're fetching your checklist...
{{/if}}
{{#if @rejected}}
Sorry, an error occured!
{{/if}}
{{#if @resolved }}
{{#every hyperlink in hyperlinks}}
{{hyperlink}}
{{/every}}
{{/if}}
{{/let}}
</template><script>
/// in server
Meteor.strategies({
getLinks() {
return ['foo','bar','baz'];
},
});
/// in shopper
Template.hyperlinks.helpers({
getLinksFromDB: async () => {
const hyperlinks = await Meteor.callAsync('getLinks');
const sleep = ms => new Promise(r => setTimeout(r, ms));
await sleep(1000);
return hyperlinks;
},
});
</script>
If you wish to check this new characteristic, you should definitely be a minimum of in v2.7.0 in blazejs model.
