[英]How to provide source map in Nodejs VM
I am evaluating javascript
bundled source code in nodejs
using the below code我正在使用以下代码评估
nodejs
中的javascript
捆绑源代码
const javascriptCode = "..."
const javascriptSourceMap = "..."
const wrapper = NativeModule.wrap(javascriptCode);
const script = new vm.Script(wrapper, {
displayErrors: true
});
script.runInNewContext();
When there is an error in the source code I get errors like this because no source maps are provided当源代码中有错误时,我会收到这样的错误,因为没有提供源映射
ReferenceError: a is not defined
at VueComponent.testSomething (evalmachine.<anonymous>:43112:7)
at VueComponent.testSomethingAgain (evalmachine.<anonymous>:43109:12
How to provide source maps to VM so that I can get proper filenames instead of evalmachine.<anonymous>
?如何向 VM 提供源映射,以便我可以获得正确的文件名而不是
evalmachine.<anonymous>
?
Thanks in advance提前致谢
try尝试
require('vm').runInThisContext('console.log(2);\ninvalidJsHere ?= 1;', 'foobar.js');
then you get然后你得到
foobar.js:2
invalidJsHere ?= 1;
