问题 I am running noflo-ui locally and trying to replace default set of components with my own set. This is very similar to the question add/remove components in noflo-ui, but provided answers are not correct for current version of noflo-ui. At least there is no preview/component.json in the repository anymore. I do not want to use github nor flowhub, due to internet connection limitation. Is there a solution for current version of noflo-ui (which is 0.18.0) ? 回答1: I assume you're talking about

how to add a noflo chart/plot component

由 夙愿已清 提交于 2019-12-13 01:28:41
问题 I have a time-series-style array of data I would like to pass into a noflo component which displays the data in a cart/graph/plot using the browser runtime and the flowhub ui. I've browsed through the component library and not found a relevant component. I'm familiar with several charting libraries and am willing to write it myself, but am unsure how to fit this into a component. is there a charting/plotting component that I missed? I've seen noflo-ducksboard, but I really want to be able to

NoFlo Error: TypeError: Object #<Port/ArrayPort> has no method 'isAddressable'

问题 I recently started getting the errors: TypeError: Object #<Port> has no method 'isAddressable' TypeError: Object #<ArrayPort> has no method 'isAddressable' I am creating the ports on my components like: this.inPorts.in = new noflo.Port(); 回答1: It looks like you have NoFlo 0.4 or older somewhere in the mix. the isAddressable method was added in 0.5. Look at npm list to see what packages you have installed an older, incompatible version of NoFlo. 来源： https://stackoverflow.com/questions/24295978

add/remove components in noflo-ui

由 好久不见. 提交于 2019-12-11 12:22:24
问题 I've cloned noflo-ui from github and am running locally but cannot figure out how to add/remove components from the noflo-search box. Ideally, I would like to remove all components from the search results and show only a the ones from my component libraries. The readme states that libraries can be added by modifying preview/component.json , but removing libraries seems to have no effect. After reading through the docs on components and the spec for component.js I tried editing /component.json

How to simulate an 'error' event on MongoDB

由 ⅰ亾dé卋堺 提交于 2019-12-11 02:25:30
问题 I'm trying to write a test case for a NoFlo component (written by a colleague) - where the component has a "connect" inPort and an "error" outPort like: var self = this; // a NoFlo Component var mongodb = null; self.inPorts.connect.on("data", function(uri) { mongodb = mongojs(uri); self.outPorts.connected.send(mongodb); mongodb.on("error", function(error) { self.outPorts.error.send(error); }); }); So based on this code pattern, how should I simulate an erroneous situation (in the test case)

问题 I got a simple noflo example running from noflo . But I'm having no luck figuring out how noflo should work with node and other code.
