How to add img src attribute with VueJs - node.js

Question

In my NodeJs route, I have the following:
router.get('/list/:id', function(req, res, next) {
request("http://localhost:3000/api/journal/" + req.params.id, function(error, response, body) {
var json = JSON.parse(body);
res.render('listdetail', { title: 'Journal', data: json });
});
});
The data is a json object containing all my screen fields. One of the fields is a base64 presentation of an image.
Then, in my List Detail html I have the following:
<div id="app">
<img class="materialboxed" src="{{data.base64Image}}" width="200">
</div>
This is surely not working... How can I add to the src attribute the base64 information that was sent by NodeJS?
I tried also the following:
<img class="materialboxed" :src=imagebase64Source width="200">
<script type="text/javascript">
var app = new Vue({
el: '#app',
data: {
imagebase64Source: {{data.base64Image}}
}
})
</script>
But it obviously does not work
Thanks
EDIT:
Strange, it's working now!
Here's what I've done:
<img class="materialboxed" src="{{ data.base64Image }}" width="200">
The only difference I can see is the spacing between the mustache.
Thanks to all who helped.

You can do it simply like this:
<template>
<div>
<img :src="image"/>
</div>
</template>
<script>
module.exports = {
data: function() {
return {
image: //your b64 string there
};
}
};
</script>
Pay attention by the way, depending on what you have on your string, you may have to add a header to the raw string.
<template>
<div>
<img :src="imgWithHeader"/>
</div>
</template>
<script>
module.exports = {
data: function() {
return {
image: //your b64 string there
};
},
computed: {
imgWithHeader() {
return 'data:' + MIMETypeOfTheImage + ';base64,' + this.image;
}
}
};
</script>
Of course you should figure out what is the type of the image, in this case.

I think the method you tried should work if the syntax is corrected
So this:
<img class="materialboxed" :src=imagebase64Source width="200">
<script type="text/javascript">
var app = new Vue({
el: '#app',
data: {
imagebase64Source: {{data.base64Image}}
}
})
</script>
should be changed to this:
<img class="materialboxed" :src="imagebase64Source" width="200">
<script type="text/javascript">
var app = new Vue({
el: '#app',
data () {
return {
imagebase64Source: data.base64Image,
}
}
})
</script>
